Study: Using 3D Printers for Household Products Could Save Hundreds of Dollars

3D printers are now more affordable and easy to use
Three-dimensional printers were once considered too expensive to be part of the typical home's collection of gadgets, but a new study says that idea is changing.
Michigan Technological University researchers -- led by associate professor Joshua Pearce -- have found that it could be cheaper for
households to buy a 3D printer
and create their own products than to buy them from stores.
Three-dimensional printers take materials, such as plastic, and create products by printing layer upon layer from the bottom up, following a specific design.
Pearce and his team came to this conclusion by identifying 20 common products found in the typical American home. They used the website Thingiverse, which offers free designs of these products for 3D printers.
After choosing the 20 designs, they looked at Google Shopping to see what the highest and lowest prices were for these items if they were to be purchased online (minus shipping charges).
They then looked at the costs of purchasing the material for the 3D printer to use for product creation, and compared this data with the Google Shopping prices.
The result was that the average American household would spend anywhere between $312 and $1,944 for the 20 chosen products online as opposed to just $18 if they made them with the 3D printer.
The 3D printers themselves cost anywhere from $350 to $2,000. Pearce said the 3D printer would pay for itself anywhere from a few months to a few years time.
"For the average American consumer,
3D printing is ready for showtime
," said Pearce. "Say you are in the camping supply business and you don't want to keep glow-in-the-dark tent stakes in stock. Just keep glow-in-the-dark plastic on hand, and if somebody needs those tent stakes, you can print them."
"It would be a different kind of capitalism, where you don't need a lot of money to create wealth for yourself or even start a business."
Pearce said the fact that prices are starting to come down for 3D printers, and the fact that it no longer requires an engineer to figure out how to use one, will make 3D printers more ubiquitous in the home in the coming years.

RE: But, Does Anyone Actually Need Those Parts?

The thing to consider is how long will it take you to model all these replacement parts? You have to have very precise measurements, which isn't going to be easy for most people. When the day comes where manufacturers give you access to replacement part 3D files, then it will be a lot easier. Or, of course, when entire products can be printed with plans. But alas, now we have assembly to worry about. So ultimately, is your time worth the massive time investment? Still, I think one would be a fun thing to have to play around with.

"When the day comes where manufacturers give you access to replacement part 3D files, then it will be a lot easier."
No doubt manufacturers will charge you to use their plans.
Maintaining adequate stock and distribution of spare parts for an acceptable price is a challenge for manufacturers. If they could just charge you to let you do all the work yourself? They'd be all over that.
What this article and most proponents of 3D printing neglect is the cost of developing intellectual property. Anything that is more cost effective to print is generally protected by intellectual property laws because thats whats being sold. 3D printing isn't big enough where big companies have the incentive to sue websites like Thingiverse for copyright infringement.
