Study Finds 3D Printers Pay For Themselves In Under a Year 322
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.'"

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

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).

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

Dude, you realise that people actualy DO buy soda at the movie theater... no?
But you wouldn't use "movie theater" as your benchmark for soda prices, though, would you?

Order and wait? Are you crippled? You go to the store and have the rings at your place in 30 minutes (unless you live really far from a store).
Have we grown so lazy that we dare not leave our places any more?
Convenience is one thing, laziness is just inexcusable.
