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.'"

    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?

      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.

  3. SHOWER RINGS!? by Dahamma · · Score: 5, Insightful

    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.

    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.

  5. The benefit is in custom parts by thegarbz · · Score: 5, Insightful

    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.

    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".

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.

    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?
