Study Finds 3D Printers Pay For Themselves In Under a Year

Lucas123 writes "Researchers using a RepRap open source 3D printer found that the average household could save as much as $2,000 annually and recoup the cost of the printer in under a year by printing out common household items. The Michigan Technical University (MTU) research group printed just 20 items and used 'conservative' numbers to find that the average homeowner could print common products, such as shower rings or smartphone cases, for far less money than purchasing them online at discount Websites, such as Google Shopper. 'It cost us about $18 to print all [20] items... the lowest retail cost we could find for the same items online was $312 and the highest was $1,943,' said Joshua Pearce, an associate professor in the Materials Science and Engineering Department at MTU. 'The unavoidable conclusion from this study is that the RepRap [3D printers] is an economically attractive investment for the average U.S. household already.'"

Apropos lowest retail cost

[c0lo]

I wonder... have they tried our Chinese friends?

Re:Apropos lowest retail cost

[c0lo]

... I think the 3D printer would take a long time to break even.

Unless... mmmm... unless our friends start selling 3D printers at lower prices. Probably in a year or two.

[Dunbal]

Without considering that a set of shower rings can last 5 years or more... I think this study is obviously bogus. I honestly can't think about any bunch of stand-alone plastic items I spend $2000 on every year.

Yep. At which point forget reprap, makerbot, and all other similar designs. They'll figure out how to manufacture these things the same way that inkjet printers are manufactured:
1) A handful of injection-molded parts that can be manufactured at 10 cents a part, and at a rate of tens of thousands per-day
2) Super-dedicated electronics with just a couple of significant ICs -- the logic chip (probably some MCU initially, and eventually an ASIC) and the motor-driving chip
3) Optimized motors which they buy in groups of 100,000 from another manufacturer in the same province
4) compact, light-weight designs so that they can pack countless units into a single shipping container

All this aristocratic "Look at me! I spent $2000 on a Makerbot!" bullshit will disappear. Oh, and just like printers -- the most expensive part will be the "ink".

Re:Apropos lowest retail cost

[derGoldstein]

This is an article that's deigned for SEO. Anyone with any inkling of how these things work and the quality of the products would call BS instantly. An iPhone case? You can get a beautiful, highly-detailed case for your phone for $2 on ebay, but you're going to opt for a rough, "pixelated", bad-fit 3D-printed one? This study would only apply if you looked for the stupidest possible way to buy things -- the equivalent of buying a soda in a movie theater.

Exactly. The actual paper is behind a paywall that I have access to. So below I'll include a list of their 20 items. I can't imagine buying any of these annually. The bulk of the $2000 claim comes from two items which significantly skew the statistics.

The first is a medical orthotic, the retail price of which they set at $800, and which the majority of people in the world without fallen arches/foot problems will never need.

The second is a shower head which they price at $437.22. Again, you don't buy a shower head every year, the $400+ ones will have a 10-year warranty and are going to be of significantly better quality than what comes out of a 3-D printer.

Additionally, in a clear attempt to boost costs, 6 out of the 20 items are overpriced Apple accessories: iPhone 5 dock, iPhone 4 dock, iPhone 5 case, iPad stand, Nano watchband, and an iPhone tripod.

The full list of 20 items:
iPhone 5 dock
iPhone 4 dock
iPhone 5 case
Jewelry organizer
Garlic press
Caliper
Wall plate
12 x Shower curtain rings
Shower head
Key hanger (3 hooks)
iPad stand
Orthotic
Safety razor
Pickup
Train track toy
Nano watchband
iPhone tripod
Paper towel holder
Pierogi mold
Spoon holder

And you think they are the people who are going to buy a 3d printer, search and find the templates they need and print it themselves?

Re:Apropos lowest retail cost

[coofercat]

I don't disagree entirely, but I'd like to add that it's not quite as simple as you make out. As an Ultimaker owner, I've found that very small details make a huge difference to print quality. I've also found that as the machine's design evolves, so does the 'ease' of getting quality out of it.You can get some really astounding quality out of an Ultimaker, but it takes hours and hours to print, and simply printing again doesn't always yield the same quality as it did the first time. I seriously doubt people will want to wait hours for their $2 curtain rings, and they certainly won't want to tinker with the machine and software for an hour before printing, or indeed put up with failed prints.

Lastly, the quality of the model has as much to do with the outcome as the printer itself. I've tried some truly horrible models that I've downloaded, and I've also used some really good ones. Garbage in, garbage out.

Ultimately though, you will be right. It'll just take a few years until the cheap printers really can do what the more expensive ones can do. In the 2 years I've owned an Ultimaker, I'd say the cost of the quality I bought 2 years ago is down by about 30%. Paying the same as I did 2 years ago probably gets you better quality/reliability/repeatability than back then too though. And even though the Ultimaker has been copied by the Chinese, and there already are various Chinese printers available, I'm not aware of any that are credible enough to eat any of Ultimaker's lunch just yet.

Suffice to say though, you'd need to be some sort of shower-curtain weirdo to need to print enough curtain rings and whatnot to make it worth owning a printer. Popping down to your local Tescos and having them print it for you sounds a lot more likely (and is something they've talked about on their blog).

As for safety razors, what about the blades? Last time I checked, you couldn't 3D print those.

They set the retail price for the safety razor at $78!!! I'm pretty sure that for $78 in the store you'll get razors included, but the rep-rap certainly won't print any.

but I seriously doubt a working iPhone dock could be made. Last time I checked, you had to get all of those connectors to be able to plug into your iPhone..

The iphone 5 dock is priced at $30, and the iPhone 4 dock $40. I don't know what they are printing that they think is comparable to those, but it certainly won't be functional.

And let's not forget the time involved. These low-end printers aren't supposed to be left unattended while operating, so at a an estimate of 4 hours per object created, assuming each design is perfectly designed and no clean up time, there is 80 hours. If you estimate your time is worth $10/hour, that is another $800 of cost. Or put differently, those shower curtain hooks may cost $0.50 of ABS plastic, but $40 of time. Then there is the time involved to sit down and design all of the stuff you want to print.

Of course, most people don't have that skill, so what they design, will look like crap if it even is printable or they will have to purchase designs. We went through all of this when inkjet and laserjet printers became cheap enough for consumers to own. All of a sudden, all of the print shops and graphic design houses were going to go out of business. It never happened because 1) consumer devices don't have the quality that professionals demand and 2) most people don't have the skill set to even make the consumer devices perform.

But, hey, people can fabricate a study much easier than they can fabricate good looking consumer goods with a 3D printer, and a lot cheaper, too.

Re:Apropos lowest retail cost

[njnnja]

What if I just click on 'Print it', then go on with the rest of your life until it's printed?

You come back to it 3 hours later to find that the object has separated from the raft leaving you with $20 worth of extruded plastic spaghetti. But if you babysit it the success rate goes way up.

It might have something to do with the nearby body heat, or maybe a hidden camera that verifies a person is there, or just pissed off little elves that don't want to be lonely. But yes, you have to babysit it :(

Re:Apropos lowest retail cost

[tsadi]

I'm wondering. Say I look at online photos of some really expensive shower curtain rings, make my own 3D rendering based on those photos, then print some for myself (and maybe for some friends who come over). Am I guilty of pirating? Will lawmakers see that as "stealing"?

Or how about if I copied the design of some really cool & expensive smartphone case and just printed one for myself instead of buying one. Will that be stealing?

Just wait 'til companies catch on

[Opportunist]

If you thought the whining of the content industry concerning the illegal copying of imaginary property was loud, this will be deafening.

Re:Just wait 'til companies catch on

[DerekLyons]

Today's "poor" are wealthier than they've ever been. The poor in America now frequently own personal computers, cell phones, blu-ray players, playstations, big screen TV's, and don't have any problems paying for food.

You've obviously never actually been poor or have been around actual poor people, and thus have a very deranged and clueless view of how poor people live.

BS

[mwvdlee]

In order to recoup the ~$1,000 cost of the printer and save $2,000 on household items in a year, you'd need to buy $3,000 on household items a year in the first place.
Excluding the cost of plastic and electricity ofcourse.

And not just any household items, but only household items that are made of relatively weak plastic and don't have to look smooth.

How many shower curtain rings, spoon holders and smartphone cases do you buy every year?

Also; how fast should a 3D printer be in order to produce that amount of items in a year?

Re:BS

[spazmonkey]

I design and manufacture 3d printers and even i see this as overblown BS to an embarrassing degree. 3d printers have great practical if very specific uses, but they will not save - much less even find use in - the third world, they are not and will never be self-replicating, and they won't pay for themselves in the average household anytime soon. The hyperbole spewed by the almost religious sects that have sprung up around the reprap will be the undoing of 3d printing as a serious technology, or at least set it back a decade. I am a huge advocate of 3d printing, and these crazed reprap messiah types even creep me out.

Re:BS

[tbird81]

Don't mock the article. Here's what I found from a brief Google search:
Yearly spending per household 2009:
Housing – shelter – $10,023
Pensions, Social Security – $5,027
Food – food at home – $3,465
Transportation – gasoline, motor oil – $2,384
Shower curtain rings - $2,105
Healthcare – $2,853

You'd be surprised how much the average household spends on shower curtain rings. Shower curtain ring failure is an important cause of household injury, and has a high fatality rate. Also, you probably underestimate addictiveness of the shower curtain. While you may only need the ones that came with your shower curtain when you moved into the house 15 years ago, plenty of addicts blow through new shower curtain at a rate of dozens per day.

You may have heard of Narcotics Anonymous or the AA. There's also the SCA, and a non-spiritual group called Glass door which helps people get over this dreadful affliction.

While 3d printers may reduce the cost of the curtain rings, which may help financially, they will not be doing anything for the root cause of the problem. This is just another reason 3d printers should be banned from general use.

SHOWER RINGS!?

[Dahamma]

Seriously... shower rings. Yes, that's the future of 3D printing that will save the world.

But I can't fault the summary, the article is even worse: "It blows my mind you can print your own shower curtains and beat the retail price," said Joshua Pearce, an associate professor in the Materials Science and Engineering Department at MTU.

So now printing a couple 1" diameter pieces of hard plastic more or less equates to an entire shower curtain? Seriously, go Michigan Technical University, your academic rigor speaks for itself! And in all of my years of eating I never even realized I needed a "spoon rest", but apparently I'll save up to $2000 by printing my own vs whatever barbaric technique I have been using to somehow keep my spoon on the table.

just no

[bloodhawk]

'The unavoidable conclusion from this study is that the RepRap [3D printers] is an economically attractive investment for the average U.S. household already.'"

No, the unavoidable conclusion is these researchers have no clue as to what the average householder uses and further more they are financially inept when it comes of where and how to shop for said items.

Re:China

[c0lo]

Does this mean 3D printers put China out of business?

You wish... what it actually means: China will be the number one 3D printer manufacturer.

The benefit is in custom parts

[thegarbz]

I have had a long hard think about 3D printers and I could not come up with one, NOT A SINGLE ONE, example of where I would 3D print something which I could just buy commercially and be better off. Why would I want a phone case made of a single colour plastic when there's a plethora of cases on the market with fancy designs, colours, custom grips, etc.

For me the desire for a 3D printer is not replace things I buy but to make things I can't. Custom cases for projects, little stands and holsters for things, the indexing latch on my 20 year old coffee grinder for which there's no longer a replacement part (though a screw through a piece of wood is working fine at the moment). I could do so much with a 3D printer, and I will once the price comes down further, as it has been for the past few years.

Not only from China. There's probably plastic mines all over the world.

[AlphaWolf_HK]

Chandler, Arizona is the location of the worlds most advanced semiconductor fabrication plant, and Intel owns it. Yet everything you buy that comes out of it is stamped "Made in Malaysia."

Why? That's where it's packaged.

I shouldn't have used the word domestic like that though - domestic could imply domestic to the US, but in reality many secmiconductor fabs are located abroad, but often not in China, and are domestic to the actual company who designs the chip (which is what I meant) - usually Japan, South Korea (Samsung being a big one), and even Europe. TSMC is probably the biggest in China, though some argue Taiwan isn't China.
