It may seem like a stretch to envision a 3-D printer in every home. However, a Michigan Technological University researcher is predicting that personal manufacturing, like personal computing before it, is about to enter the mainstream in a big way.

“For the average American consumer, 3-D printing is ready for showtime,” said associate professor Joshua Pearce.

As Tomorrow in Review readers know, 3-D printers deposit multiple layers of plastic or other materials to make almost anything, from toys to tools to kitchen gadgets. Free designs that direct the printers are available by the tens of thousands on websites like Thingiverse. Visitors can download designs to make their own products using open source 3-D printers, like the RepRap, that you build yourself from printed parts, or those that come in a box ready to print, from companies like Type A Machines.

3-D printers have been the purview of a relative few aficionados, but that is changing fast, Pearce said. The reason is financial: The typical family can already save a great deal of money by making things with a 3-D printer, instead of buying them off the shelf.

Pearce drew that conclusion after conducting a life cycle economic analysis on 3-D printing in an average American household.

In the study, Pearce and his team chose 20 common household items listed on Thingiverse. Then they used Google Shopping to determine the maximum and minimum cost of buying those 20 items online, shipping charges not included.

Next, they calculated the cost of making them with 3-D printers. The conclusion: It would cost the typical consumer from $312-1,944 to buy those 20 things, compared with $18 to make them in a weekend.

Open source 3-D printers for home use have price tags ranging from about $350-2,000. Making the very conservative assumption a family would make only 20 items a year, Pearce’s group calculated that the printers would pay for themselves quickly, in a few months to a few years.

The group chose relatively inexpensive items for their study: cellphone accessories, a garlic press, a showerhead, a spoon holder and the like. 3-D printers can save consumers even more money on high-end items like customized orthotics and photographic equipment.

3-D printing isn’t quite as simple as 2-D printing a document from your home computer — yet. “But you don’t need to be an engineer or a professional technician to set up a 3-D printer,” Pearce said. “Some can be set up in under half an hour, and even the RepRap can be built in a weekend by a reasonably handy do-it-yourselfer.”

It’s not just about the money. 3-D printing may herald a new world that offers consumers many more choices, as everything can be customized. “With the exponential growth of free designs and expansion of 3-D printing, we are creating enormous potential wealth for everyone,” explains Pearce.

Before 3-D printers become as ubiquitous as cellphones, they could form the basis of small-scale manufacturing concerns and have huge potential both here and in developing countries, where access to many products is limited.

“Say you are in the camping supply business and you don’t want to keep glow-in-the-dark tent stakes in stock,” Pearce said. “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 study is described in the article “Life-Cycle Economic Analysis of Distributed Manufacturing With Open-Source 3-D Printers,” published in the journal Mechatronics.

It’s co-authored by Pearce; students Ben Wittbrodt, Alexandra Glover and John Laureto; lab supervisor Gerald Anzalone of Michigan Tech’s Department of Materials Science and Engineering; Douglas Oppliger, Engineering Fundamentals lecturer; and John Irwin, an associate professor in the School of Technology and program chair of mechanical engineering technology.
