Study: At-home 3-D printing could save consumers 'thousands'

By Heather Kelly, CNN

Personal 3-D printers may sound like a pricey luxury or a niche product for geeks, but soon they could become a household appliance that saves people thousands of dollars a year.

Researchers at Michigan Technological University conducted a study to find out how much a family might save by printing common objects, such as simple replacement parts or toys, at home instead of buying them in stores or online.

"It was relatively shocking what the return on investment was," said associate professor Joshua Pearce, who led the study. "Realistically, it's in the thousands."

Much of the recent 3-D printer hype has focused on how the technology is going to revolutionize the manufacturing industry or what cool things it can create - human organs, duck feet, see-through hermit crab shells shaped like cities. But it's the small, mundane objects that could have the most immediate impact on wallets. (Especially if you print your own wallet.)

Printing 3-D objects does require a big upfront investment. Current desktop 3-D printers cost between $350 to $2,000. For the study, researchers used a $575 RepRap printer and selected 20 free 3-D designs that were available online.

Their calculations didn't take into account shipping costs or sales tax associated with buying from a retailer. The researchers say they did that to keep the estimates for the study on the conservative end.

"We assumed the average family would only make 20 items a year, which is silly because if you get one of these you'll make 20 items in one weekend," said Pearce.

The MakerBot Replicator 2 is one of the more popular desktop 3-D printers.

After printing all 20 objects, the researchers tallied the cost of plastic and electricity needed to make each and compared it to the low- and high-end versions of the same product from retailers. For example, a shower head costs $2.53 to make on the 3-D printer (3 cents for electricity, $2.50 for plastic). A comparable model costs anywhere from $8 to $437 at a store.

According to the study, the biggest savings were with objects that could be customized, like orthotic insoles for shoes. A custom insole can cost $500 to $800 from a retailer, but someone could create an insole on a 3-D printer for about $2. It does take more skill - and advanced equipment, like a 3-D scanner - to create the custom shape, but once you have the optimal design it's simple to produce multiple copies with no additional effort.

The team printed a variety of doodads for the study, including an iPhone case, garlic press, safety razor, perogi mold and spoon holder. Smaller mass-produced objects saved the least amount of money - a dozen 3-D printed shower rings cost $1.20 to print and $2.99 to purchase from a store. The iPhone 5 case cost 27 cents to print, a huge improvement over the inflated $20 price tags found in Apple Stores and other retailers.

Printing all 20 objects took about 25 hours and cost a grand total of $18 in plastic and electricity. The savings came out to between $294 and $1,926, depending on the quality of the comparable retail products.

Free open-source files are a key part of keeping 3-D printing costs low. There are online databases of designs, like Thingverse, that anyone can download and create with printer at home. If you pay for a 3-D design or invest time in making your own, the cost per object will go up.

Pearce says replacement parts will be a major category for personal 3-D printers. Customization will be another big trend in the future, as people turn to these printers to create things they can't find at a Wal-mart. The types of printable materials will expand as well. Right now you can only print a plastic smartphone case, but in the next year you should be able to print a case with an antenna in it. After that, whole circuit boards for the phone.

And desktop 3-D printers wouldn't just save cash; they could also help save the environment by cutting down on packaging and pollution from transportation.

The technology of 3-D printing has improved in recent years. Higher-end models can be used by anyone with minimal set up and training, and using pre-made files means you don't have to know how to create a 3-D design. Improved software is already making it easier to customize those designs with an easy-to-use interface.

Instead of a 3-D printer in every living room, Pearce can also see local stores setting up 3-D printers. The cost to consumers would be slightly higher, but they wouldn't need to buy a printer - and that paper-towel holder will still be cheaper than a retail model.

    I couldn't agree more. I think what needs to be done is we need the blueprints of all house hold items to be stored somewhere so we can download and print them as we need them. They must be easily found.

    I wonder if this can make a clear, thin, flexible, 4 color template about 6" x 8".

    I also have questions about what kind of fumes might be emitted. Would these be carcinogenic?

    Thanks!

      Many different printers can print with a 8" by 12" footprint. Printing in multiple colors/materials requires a separate filament driver, hot end, and electronics for each one. Since these go for about $50.00 each, it quickly gets expensive.

      As for fumes, that really depends on what material you use. Currently, the two most common plastics used in 3D printing is PLA and ABS. PLA is made from plant starches, mostly cornstarch, and doesn't out-gas anything harmful at its melting temperature. ABS does out-gas trace amounts of Hydrogen Cyanide, but you would need to be in a unventilated room for several days with a constantly running 3D printer before there is enough to do you harm. Other materials, such as Nylon, can be a bit more dangerous, but usually if you print in a well ventilated room you should be fine.

    Heather Kelly – why does CNN want you to write a story like this with so much hype? The story could have been fine without, "comparable model costs anywhere from $8 to $437 at a store." You will not print a $437 shower head. why not do some research and write, "comparable model costs anywhere from $8 to $77 at a store." – that might be believable. Or custom orthotic insoles for " $500 to $800 from a retailer, but someone could create an insole on a 3-D printer for about $2" – hype! not useful information

      3D printers are for prototyping or making unique/hard to find parts. For manufacturing you're better off using one of the tried and true methods of mass production.

    ROTFL. We run an industrial 3D printing service bureau and even at 24/7 operation with bulk discounts on consumables, discounted tech support, operating with economies of scale, manage a minimal profit for the amount of investment. With the slow, low quality machines available to consumers on a budget, it's a net money sink. Unless the machine can print diamonds from carbon dust, it's utterly laughable how they can make money. Average home user will lose inordinate amounts of time and money trying to print a sub-par plastic part that he can get a dozen for 25 cents in a hardware store. If the personal satisfaction is worth it, more power to them. But 3D printing is not a money saver, it's a time and money sink just like any other hobby. Once the novelty wears of, 95% of home printing adopters will be left with broken and dusting impulse bought toys and thousands of dollars lighter in their pockets. The other 5 percent will still be losing money, but they will be happy with their new toy and hobby at least.

      I couldn't agree more. 3-D printing does have a place but most people don't have the required skill to make the drawings much less the ability to visualize their net product as a finished item. Ignore Eric. I have been using 3-D printers such as the Stratasys Water Works FDM 2000 model since 2001 and they have serious limitations as well as great potential. PolyJet and glass reinforced parts are good mechanically but it is time consuming and expensive to operate the machine. Eric is obviously a technologically challenged liberal from his language.

    Before y'all start naysaying, "Researchers at the University of Warwick have just taken a huge step in the right direction with the introduction of a 3D-printable electrically conductive plastic. They’re calling it 'carbomorph.'" [wired . com]

    Now, you can make circuits. As this particular technology advances with higher resolution printers and carbomorphs with a variety of conductive compounds, we're not very far from making our own computers and mobile phones. Rather than Cyan, Magenta, Yellow and Black, we'll have Conductor, Semiconductor, Insulator and Transparent (for fiber optics and optical computers… and Barbie dollhouse windows).

    Here's a better experiment:
    1) Give 100 random people with no prior experience a 3D printer and a pile of common household items.
    2) Ask those people to find, buy, and pay for the common items in stores.
    3) Now ask those same people to use the 3D printer to make the same parts.

    Now I *really* want to see the outcome of this experiment...

    I challenge anyone with a 3D printer to do the following..
    1) Keep receipts for every piece of plastic, object, part or hardware or some small household fix that you bought in the last 3 months. Total the receipts.
    2) Now write down how long it would take you to find or make cad models, print those parts (if possible), polish them to working order, and print them on your 3D printer without defects. Take that time, multiply by your hourly pay rate, then add on the material cost of the ABS plastic.
    Now compare the two costs.......

      Time and progress move forward, 3d printing for the home is in it infancy, just like computer were in the 80's. I can see a time when people rather than buying a product they can make it, the company sells the plans for the part or thing. Nokia has released its files for some of the cases to their phone so people can customize them. Will I run out and buy one, probably not, but I do see a future. Who would have thought 10 years ago cell phones would be as powerful as they are today and people making money selling apps for those phone. Technology changes embrace it or move out of the way.

    Copyright laws introduced by crooked politicians impedes the usefulness of the 3D printers. The United States' copyright laws have been twisted and warped over the years. What was once less than 30 years for a product to lose it's copyright and patent protections has been pushed past 100 years so innovators will never get a chance to innovate and improve the existing product. Designing from scratch takes time and money and even if you came up with the idea all on your own, there is a chance that a patent has already been filed which would bar you from ever using your invention. The copyright laws have been forged not to encourage innovation but to cultivate greed.

    I don't understand the negativity I'm seeing in the comments. I'm all for being practical but not at the expense of imaginative or critical thinking. This technology is in its early stages. It's not going to get worse or less capable from here on out. The opposite will happen, as it always does; it will evolve and become even better.

    Knocking 3D printing because of what it can't do today is just as shortsighted as mocking the computers of 25 years ago for what they couldn't do.

      What I don't understand is what materials are they using to make these objects? I'm thinking of printers like the ones we have now. Obviously they would need to use plastics etc. Do these come in sheets like paper? I need to see one of these in action. Hopefully since I've been a cad drafter/designer for over 30 years I can design my own stuff easily enough it's just the actual process that I have no knowledge of.

    Im surprised no one has mentioned mold making. Probably a nearly lost skill these days except in manufacturing.

    You print the mold in the weaker material and then use the mold to make the part out of what ever strong or softer material you need for your application, like metal casting, carbon fiber, fiber glass, foams, silicone etc.

    Just think, custom jewelry, car parts, eyeglass frames, artificial limbs, Halowen masks... there is no end to this list.

    Until you can print strong multi materials directly, theres always the mold technique and THAT does lend itself to mass production if you are so inclined.

    This is cool and I'm glad its being shared open source.

      LEGO could always cash-in on it by releasing for-pay designs for more intricate pieces (ie: better tree's for City builders, cooler looking guns for spaceships in the Star Wars line, etc...).

      The time it would take to 3D print an entire Lego set (sometimes in the 1,000's of tiny pieces) would be huge since each piece would need to be done individually or maybe in small batches.

      Lego has nothing to worry about. The time it would take to print out enough parts to make a set would make it not worth it. The money savings is going to be offset by the time. Plus, their licenses give them an advantage.

        Even if printing of blocks becomes faster/easier in the future, it doesn't necessarily hurt Lego which could just sell digital versions of the sets, at a much higher profit ratio since they wouldn't need to buy plastic, make it into blocks, pack it into boxes, design and print instructions, get a retailer to buy it, and ship it to them.

      LEGO is an exception. Most plastic toys are quite inexpensive. (Barbies are about $5 a doll.)

      Aside from the iPhone case and a few other exceptions, most of the stuff they cite is stuff that costs under $5 at Target. A plastic pencil box for my kids' school supplies? Why would I go to the trouble of making it myself when China supplies me with an endless array of colored boxes from which to choose at Target? For the things that are hard to find and expensive, I guess I could see it, but Chinese production of cheap plastic goods will give 3D printing a run for its money for the foreseeable future.

        I'd rather print my own plastic products than continuing to give our nation's money and jobs to China. We have become nearly completely dependent on their cheap labor and undervalued curency. It's become nearly impossible to find basic non-food items that are NOT made in China. I would be more than willing to pay more for something if it was made (or printed) the United States, than to give one more dime to the Chinese.

        3-D printing right now is best for industrial purposes; the whole idea will probably come to maturation in the next 15-20 years, but remember, some products are too big to make at home, and some people don't want to use them or won't be good with the 3-D CAD you need to use to make stuff of your own design. Real manufacturing will never go away, but I can see large amounts of re-definition coming- even more than we've already seen.

      It's probably cheaper to buy and melt a lego set and extrude it into a spool to use in your personal 3d printer to print your lego set than buy a spool to print your lego set. Think about it for a minute.

      LEGO....Well, thirteen years ago when we purchased a high-end 3D Printer from Stratasys, we were doing LEGO "Battle-Bots" for underclassmen who had no machining/designing skills and the BEST parts we could turn out as custom "LEGO" parts were not as good mechanically as standard LEGO components (Mindstorms/MECHANICA specifically) and would readily break and not hold tolerance. Students resorted to super-gluing assemblies which disqualified them. 3D printing is best used for product visualization/prototyping as the plastic resins and even METAL are not capable of being engineered as well as standard engineering plastics and metals.

      Well, I have a use for one already: I have an old Grundig living room stereo from 1950. All the knobs and dials are even in German. But one interior mechanical part was made from cheap post-war "pot metal", which became brittle disintegrates to the touch. It's the arm that moves the relays to switch between phono, AM, and shortwave radio, so without that arm most of the features are useless, and needless to say, a replacement part would be impossible to get. But I could print a plastic replacement arm and get it working again, and even if I had to print a new one once a year, the fix would still cost next to nothing.

      Have all of the doubts in the world about the benefits of 3D Printing, but as these devices get better and better cheap[er and cheaper they have a huge impact the economy. So they will not only be printing in plastic but several other types of material at the same time, and the possibility of them printing electronic components is not to far in the distance either.

      I have and still use the technology and production parts will always be better for general consumer use. This article is mostly hype. 3D printing has it's uses/benefits but is slow to use and will always produce a lower quality part than other production means. Some of those cups and things you see in the article look cool but would generally take hours (if not a day or so) to produce. The finer the surface detail and the denser the build, the longer it will take to produce. IT'S PHYSICS, not wishful thinking that will control the market.

Basically, layered resins have a tiny fraction of the strength of injection-molded parts, so in any case where a plastic part has broken on some device, it's extremely likely that the "printed" part won't last any length of time at all.

    The iPhone case example is plain stupid, since you can get a perfectly good, and probably better than printed, case at a dollar store for a buck or two.

    Rapid -prototyping- has a place, but it's not in high-volume manufacturing, nor day-to-day home use.

      I was thinking something along the same lines. While I can believe that 3D printers will evolve to the point that the finished product will be as good as what you can buy at the store, as some of these produce parts that are very strong, I still can't see how it would be cost effective for most people. Let's take a broken PVC pipe.... I can go to Lowes and buy 5 feet of PVC for a buck or two. I'd have to print a heck of a lot of pipe before I saved any money given the cost of a 3D printer and it's own material input which isn't free.

        Yes, printing a one-foot long piece of pipe that would replace a 3 inch PVC version would break/leak (through the pores)quickly and would take about 10-12 hours to "build". This is the voice of experience.

      Just wrong - Yes you could get a dollar store iphone case but it will be crap and it will still cost MORE than the 3d printed variety. The ones people think are cool are customized – personalized and that is what 3D printing has in spades.

      Yes, cheap and weak. I suppose the ability to print a friggin gun isn't strong enough for you? I bet back in the 80s you thought the PC was just a stupid toy that would never amount to anything. You're short sighted my friend. There is a massive amount of applications this technology can be used for. A printer large enough could construct buildings, one small enough could make semiconductors, one powerful enough could print with metals, endless possibilities.

    As much as I think 3D printers are cool, they aren't going to be in every home. First of all, not everyone wants things made of plastic. And who knows what quality of plastic that will be in the first place? Second, if you are talking about decor, many people don't know what they are looking for until they see it on the shelf.

    So it's a neat technology, but so was the advent of quality "pro-sumer" video cameras that were supposed to make everyone a film director, too, and that didn't happen. Just because you can get the tools, it doesn't make you a good or creative craftsman.

    This is called rapid proto-typing and has been around for 20 years. Unless you are into making cheap plastic models it's not much of an asset. They do have a 3d liquid metal "printer" proto-type that shows some merit. Give the tech another 20 years. 50 for a food replicator.

      Sure rapid prototyping has been around a long time – but the innovation killing patents are finally dead so rather than spending 30 grand for a 3D printer now you can build one yourself for a few hundred and then make a lot of the plastic products in your house.....which is a lot.

    Did anyone notice the article was about open-source reprap 3D printers - the kind that print their own parts and fix themselves - yet all the photos were of Makerbot printers that are now closed source Stratasys systems? Yeah sure if you print a few dozen products you can pay for any desktop printer - but to get a really high return on your 3D printer you have to have it for a long time - and that won't work for a closed system because you can't fix and upgrade it the way you can with an open source one. I think there are dozens of open source 3d printer companies - that have as good or better products than Makerbot - but they don't get the press coverage even when the stories are about them? Why is that CNN?

    Today, for the average person, its nothing more then an expensive toy. For the average person you can print out toys, desktop items, thats about it. You can play arround with it, but no serious application. Sure you can print a shower head or somethign simlar but the material strength is not there. For the home 3d printers.

    However, this technology's promise can not be overestimated. It has the potential to change everything. But where not there yet.

    3d printed organ replacement. Is happening right now. For simple organs. Bladders, esophegai, etc have been printed and implanted for years now. A functional mouse heart was printed several years ago. Its only a matter of time before complex organs like a kidney is printed. Image the the idea of wait lists for organ replacement being a thing of the past. 5-10 years and it might be a reality.

    And if you can print functional organs, you can certainly print a steak for instance. Thats being done now as well, tho its far too expensive at this point.

    3d printed rocket parts, happening right now. Extremely complex rocket engine injectors have been printed and test fired. Thats impressive, because of the stress those parts have to endure.

    Once you can print rigid plastic, elastic plastic, metal, semiconducting, etc, all in one pass without finishing steps. Now you have something that can change the world. Were at least 10 years off for that. And then longer for the price to come down to being in every home.

    The advances over the last couple lears in additive manufacturing have been pretty amazing tho. Were just not there yet for the average person.

        Look around your home how many things are made of a single piece of plastic? 3D printers cant even make a single piece of plastic with four different colors (toys have many different colors) let alone items that are made of multiple types of plastic plus rubber, plus glass, plus multiple types of metal ... 3D printers are no where near that. Try printing a TV remote control and get back to me in 30 years when it is done.

    This article is almost good enough for The Onion. As a Makerbot owner, I had to cringe and laugh a little while reading it.

    The printer could make cheap replacement parts. But, the user would either have to have the original 3D CAD file or a decent copy. Why would any product manufacturer share their 3D drawings? And if an accurate model was obtainable, the user could recreate the physical model but not the original product's characteristics. Ie. a plastic "safety razor" would appear similiar to the original but wouldn't be sharp enough to cut. A plastic custom shoe sole would appear similar to the original, but probably wouldn't be as comfortable.

    3D printers have a future, though. They have evolved, becoming more "affordable" with more capacities. But, I seriously don't think they will alter the future of consumer products. 3D printers are well-suited for creating prototypes, scale models and perhaps toys.

    Please Note; the article shows the Makerbot Replicator 2. It currently retails for a cool $2,200. Slightly above the range the article mentions. I own this exact model. And it's not really "easy to use" or "plug n' play". I've spent dozens of hours fine tuning this machine. It's a neat machine, but it's still a "toy" for me.

      This is actually all true, with some caveats. Certain problems will be pesky enough that some people will make their own models to share with all if for no other reason just to free others (will everyone? No, but many will and the public archive will grow). Completely agree with the not 'plug and play', mine is a touchy pain (for > $2k no less) but they get better each generation and when you can custom craft circuit boards you will see awesome stuff get produced (EE's & circuit hobbyists alike will be able to afford to make small production runs of their flights of fancy...some of them will assuredly take off). The fact that you own one means like me you have some decent hopes for what this tech will become and are exploring what it is currently capable of. Luck to you man!

    I run a 3D printer at work.

    Even though I have access to the machine for personal use, I rarely find myself doing it. Last week I made a connector piece that broke on my shoe rack. Guess what? The plastic was no where near as strong as the original part, and it's already broken. Never mind the fact that it took my $6k Solidworks licensed program to draw the part in 3D. Next project is the pin I broke on my waffle iron. Hopefully I don't start a fire...

    Oh, and the resin is $50/lb as opposed to $1/lb for the industrial ABS in the parts I design. And, the resin is light-sensitive (that's how it hardens in the first place). Leave it in the sun for a couple days and thinner parts will warp.

    I love the technology, but fact is that it has a long way to go.

      Yep, recycleable. There is a device in the works that allows for home recycling. It grinds up failed or obsolete printed models and uses the plastic chips to make new plastic 'feed' wire for use in your 3D printer.

    Even with a professional SLA system costing in the hundreds of thousands, the parts still need post-finishing to look smooth and fit together. These inexpensive systems could not possibly produce parts that accurately and cleanly built, let alone any part that will subjected to a load or be exposed to temperature variables throughout its lifetime.

    This is really neat technology, but it has a long way to go. Give it time. I for one certainly have no use for a 3-D printer myself considering the limited things one can make with plastic, added with that fact that I don't go through enough shower heads or small plastic parts to justify a 500 dollar price tag for the printer. But I am sure this tech will ultimately grow into something useful in the future.

        Actually, the use of "irregardless" is not necessarily incorrect and it is definitely not a made-up word. There is some argument between linguists regarding if "irregardless" is a proper word, some believe it is correct but outdated, some believe that it has always been incorrect, and I suspect there are many, like myself, that understand what people mean when they say, write, or type "irregardless". The naysayers are probably in the majority but a reasoned argument can be made for the words use. So, to be less anal retentive, the use of the word is fine, most everyone but the very thick headed will understand what you mean but you should realize many will declare that "irregardless" is not a proper word and/or outdated.

    Umm. I don't know who thinks a printed part be it SLA, FDM, or SLS can replace real plastic injection molded parts but they really need to do thy're research. Printed parts from the machines mentioned here are flimsy and melt at 150-200 degrees Farenheit. They are made with photo-reactive resins, not polymers.
    They have nowhere near the mechanical properties or melting temps of real, tooled plastic parts. As a Mechanical designer who models, prints, and engineers parts professionally; I can't see any real or dependable use for these at home. Stick to real OEM or aftermarket parts that have been designed and developed by people with real experience. You won't regret it.

      The liquid composition is a blend of oligomers, monomers, photoinitiators and additives. There is a notable degree of skin sensitivity to these ingredients by a percentage of the general population, especially with some of the monomers. it's a great system for developing prototypes instead of having to make expensive molds and then casting them. As for parts that are intended for "real life" use, I agree, I would not touch the parts made from 3D printing. And, I would assume that the lawyers would be screaming "LIABILITY" all day long if someone actually tried to sell these to the consumer. Why not build mini nuclear reactors that you can house in your backyard and be off of the electrical grid? This technology in the hands of the average consumer would be very dangerous.

Picture the same setup using two part fast hardening material stored separetly in liquid form, like say the current crop of chemical bonding agents like "JB engine weld", which is named such becase it forms a bond in metal strong enough to repair certain types of cracks in car engine blocks ... but is just a non metal chemical blend.

    This article is very misleading or maybe the author is misinformed.

    You cannot compare a $2.53 printed shower head to an $8 discount store special much less a $437 high end version. You cannot print perfectly round nozzle holes because of the terracing inherent in the process. The printed material is also not as strong as production plastics, much less metals. The printed shower head would likely leak at the connection and would spray water in all different directions and have a life span of a week or so.

    The other examples are similarly bad. A printed phone case would offer zero drop protection for your several hundred dollar phone.

    You could print something like a Lego or other simple toy type products, but the durability will not be the same. And who is responsible now when a printed Duplo breaks in half and a 3yr old chokes on it?

    Don't get me wrong, I work in the prototyping industry and this technology provides an outstanding opportunity for designers to quickly evaluate their designs and compress the product design cycle, but they are a long long way from having a useful place in a household.

      I printed that exact shower head 3 months ago and have been using it ever since. No it doesn't spray 100% perfect but can I still shower with it? You bet. I also have a phone case that I printed that I have been using for almost a year. It replaces the thin cases you find just perfectly but won't work the same as an otterbox (but, it isn't billed to replace an otterbox). Think about the people who buy an $8 discount shower head. Odds are they are all about saving as much money as possible and not nit picky on the surface finish and spray quality. The top end might be a stretch, but perhaps the idea is to make people think about how much they spend on things that can be replaced for much cheaper. I wouldn't replace my brushed aluminum cabinet handles with a 3D printed plastic one, but making a custom wall plate for 25 cents for the plug I just put for behind my TV...why not?

    At least initially, the place where these printers are really going to shine is in R&D for little, independent inventors. Currently if you want to create a "new widget" you have to design it and then, most likely, have somebody make one. If you discover an error, or an improvement, you have to have them make another one, or perhaps re-machine the original. That cost's money. Maybe you have the tools necessary to make it yourself, but that's still a lengthy process (most likely).

    A 3D printer will make prototyping a dream. Design it, convert the drawings to instructions, and push the button. If you missed something, or discover an enhancement, take a few minutes to modify the drawing and do it again. What might take a week or more now can be done while you go to lunch...and at minimal cost. I have no doubt that people will buy them for home use too, and as the on-line library of stuff grows, more and more will do so. Plus, you can make your own Lego blocks...creating a piece that the company will never supply. What more could you want?

    Got to start somewhere. If it's affordable, it's going to have cheap applications in the first operative stages of its programming. It's cool, and it will certainly advance in following through with Moore's Law; but until it becomes more advanced, it will probably be most appropriate for parents who have a few kids. Think about all the plastic toys that are made and that children use! Supersoakers, Action Figures, Barbies, Wiffleballs/bats, etc. Kids have millions of plastic toys over the course of their childhood. So, in that respect, I can see a 3D Printer saving thousands in the long haul.

    Obviously we're not talking about metals and glasses just yet. It may already be possible, but the expense is just too large at this point. Give those kinds of applications another decade, perhaps - maybe less.

    But, overall, these are very cool. Certainly a piece of tech to get excited over.

    I'm not sure I buy this argument for a few reasons. So lets say your $2.53 shower head could replace your $437 shower head because of 3D printing? If that is the case, why couldn't the shower head manufacturer use the same technology, probably make the shower head for $1.00 in volume and sell it for $3.00, making a tidy profit. So now your savings are maybe $0.50 if you are lucky, not including your added time.

    Then there are structural issues, safety issues, and much more. If that $2.53 shower head pops off and causes injury to you, then what? Do we want products out there that nobody has really tested? That we don't know is safe? And how are you going to build things that aren't plastic?

    This all is not to say 3D printing won't change things, certainly, but will I be printing a new TV or stove? I don't think so.

    It's just a matter of time before someone breaks some item at home, scans the broken item with a laser scanner, prints it on his 3D printer, and replaces the item without any consideration for the structural integrity of the item. One of these days, someone's going to post some sort of 3D design on the interweb (like a gun or cannon), and someone else is going to kill themselves after printing the item out at home because they used the item in an inappropriate matter. Just because you CAN 3D print something, it doesn't mean you SHOULD print it. As said above, these things are great for making prototypes or toys, they're not good for making things that may see critical strains, stresses, or the like. Different printers use different plastics with different physical properties which only makes things more complex.

      I have to kind of agree. It is going to take one person printing an item and having it break in such a way as to cause damage to themselves or something else and then that person suing the maker of the printer before the industry re-examines the "homemade quality" versus "commercial" issue.

If you later decide to sell it, well then you need to put a serial number or some designation on it to comply with the law, and if you do that more than once or twice then expect a whole lot of scrutiny.

      Well I guess we can just ban 3D printers to allay your fears just like we banned playdoh because someone might want to build a suspension bridge using it ... or wait we didn't ban playdoh ... hey here's an idea if you want to 3D print a part that is used for a load bearing or mission critical application why don't we create a reputable certification process for 3D models ... engineers can join it like a guild and put their stamp on certain models suitability to certain tasks ... hmmm... to logical we should just ban anything that might lead to thinking I guess.

    As an Engineer, I've been working with "3D Printing" for over 25 years. It is a remarkable process that will have an impact in the home in the future, but, the material science needs to come a long way.

    One industrial process that is rarely mentioned is Selective Laser Sintering. This is a 3D process that melts together metal powder and builds up parts layer by layer, like in other processes.

    I have produced some medical devices out of stainless steel using SLS with geometries that cannot be machined or cast with conventional processes. The FDA even allows SLS produced parts to be directly implanted into patients.

    But the real impact will not be in making toys at home, it will be using 3D printing to build the forms for organs, such as the liver and heart, on which stem cells can attach and grow.

    Not hardly. Take a closer look at who paid for that study. It's all about marketing and guiding consumers into believing that they need one of these in every room of their house, with savings beyond the imagination.

      Right, and no 3D printer that is within reach of even fairly affluent people can print in the mixed materials required to print an item of more complexity than an iPhone case. Even the $$$$ ultra high end 3D printers aren't able to do that yet.

    These 3D printers still can't compete with large scale manufacturing. They are tediously slow and the cost to print something is quite significantly higher than other molding methods. Sure, they are good for one-off prototypes, but that's pretty much it...

      However, if your option is to use a 3D printer to create a replacement part that is not available for purchase – meaning you need to replace the *entire product* rather than replacing a simple part – you could achieve *significant* savings and keep crap out of the landfills.

      Or to replace something you need. These aren't intended for mass manufacturing.

      As long as the 3D printer is faster than the USPS, that's all I care about. I can have a replacement part in 18 hours, rather than 5 days.

      Please at least read the article before you comment. No one cares if your injection molder can spit out 10,000 kitchen gadgets an hour - I can print my own kitchen gadget at home while I am watching tv for 90% less than I can buy yours for in the store. Sorry No Sale!

    Couple a 3D printer with a 3D scanner and you might have something cool. Imagine taking the broken piece, putting it in the scanner and having a model that's already in the right dimensions. Then you just fix the model in your 3D editor and print the fixed piece. Voila!

      Imagine the consequences of not taking into consideration the physical properties of the broken item and replacing them with your structurally unsound 3D printed item. It's just a matter of time before someone gets hurt trying to do something like you've suggested. It's a bad idea just waiting to happen.

        So you're saying we shouldn't innovate because someone will do something stupid with our innovation? Should we get rid of cars too? People do stupid things with those every day.

        Yeah, because I didn't undertake a multi million dollar study involving a world renown think tank when I created new army men toys for my kid ... geez. Just because you don't exercise common sense in your life doesn't mean that everyone else in the world is just as irresponsible. Those who say it can't be done shouldn't never get in the way of those who are actually doing it! (-Einstein, i think)

    Tried it. Too expensive and leased printers do not have high enough resolution yet. Everything has micro lines even at .100mm resolution. Paid over $40.00 to get 2 and 1/2 inch model at high res and still looked bad. Wait a couple more years before buying; let the technology catch up. Right now they are in the "daisy wheel" phase.

      100 micron resolution is pretty good and now standard for most of the printers we are talking about - if that is not good enough you can do a simple chemical treatment - so for abs prints you can paint them with nail polish removier and you have your smooth surface.

      If you want high resolution don't use FDM printing, find a company with an SLA printer. So accurate you can't tell if it was made with a plastic injection mold or not. And the company I use prints clear, the Plastic is as clear as glass. If you want a quality print job, its going to cost a few hundred. You got a model that looked bad, because you only spent $40. the model wasn't cheap, you were.

    Maybe in 25 years, these 3D printers will be able to effectively print something worthwhile. Now, the only practical uses are in engineering prototyping applications. In time, factories won't need employees since, for example, completed car parts can be "printed" and assembled by robotic tools which in turn can be" printed", So the need for human labor will disappear. Even the 3D printers will be self replicating....so where will humans fit in. Or earn the cash to purchase any of this stuff?

      Just like machine tools, Rapid-Prototypers are already being used to produce more parts for new machines. See "Make" magazine.

    I use a 3D printer almost every day and love it. It was saved thousands of dollars in tooling costs for many projects from the 1 – 10 piece build to testing new parts and modifying parts before paying for a production mold. Love it, buy one. they pay for themselves very fast.
