Open-source 3D printed parts often stronger than proprietary versions

A common criticism of home 3D printers is that whilst they can easily replicate any number of shapes and objects, and print parts that look identical to plastic prints from professional 3D printers, they can only print flimsy plastic trinkets. Are RepRap prints as strong as professional 3D printed parts using the same polymers?

“We were curious too. Our prints seemed strong, but we wanted to engineer robust scientific equipment and tools for the developing world, so we needed solid trustworthy numbers.” said Joshua Pearce, an associate professor of Materials Science & Engineering and Electrical & Computer Engineering and Michigan Technological University.

Michigan Tech Study Suggests Some RepRap 3D Prints Are As Strong as Commercial 3D Printers

If you thought that plastic parts produced from your average RepRap desktop 3D printer were in any way weaker than those made with commercial 3D printers, you may be proven wrong. The research lab of Dr. Joshua Pearce at Michigan Technological University has once again put out a study in favour of low-cost 3D printing. After already establishing that such devices could create affordable open source lab equipment for universities, as well as save consumers $300 to $2,000 a year with the printing of common household items, Pearce’s lab has tried to demonstrate that low-cost 3D printers can print ABS and PLA parts with the same strength as those made with commercial printers.

3D printing with metal at Michigan Technological University

3D printing has become a useful tool, but so far has been limited in the materials it can use. Michigan Tech researchers are now developing a way to print 3D objects using metal.

Michigan Tech Study Suggests Some RepRap 3D Prints Are As Strong as Commercial 3D Printers

If you thought that plastic parts produced from your average RepRap desktop 3D printer were in any way weaker than those made with commercial 3D printers, you may be proven wrong. The research lab of Dr. Joshua Pearce at Michigan Technological University has once again put out a study in favour of low-cost 3D printing.

There’s still a great deal of research ahead of the team, to further elucidate the properties of objects printed with low-cost 3D printers, such as the effects of chemical post-processing on the strength of a print. Pearce explains, “This study only looked at the tensile strength in the plane of the print bed, next we need to expand this study to look at interlayer adhesion.”

3-D Printing is Green

CURWOOD: Back before the industrial revolution, if you needed some thing, you or someone else would make it by hand. Then along came the production line and big machines that could mass produce items quickly and cheaply. And now we are headed back to future with so-called 3D printing, where a fairly small machine can make just about any metal or plastic object simply by following precise instructions from a computer. A team at Michigan Technological University has studied the possible environmental and the financial benefits of 3D printing. Joshua Pearce led the research and explains the surprising results.

Michigan Tech creates 3-D printer

“What our group has done hear at Michigan Tech is radically pushed the cost of 3-D printers down. So commercial 3-D printers that could do plastic used to cost $20,000. Now with the Open Source project, that cost has come under $1,000 and the ones we are building with our students cost under $500,” Materials Science and Engineering Associate Professor Dr. Joshua Pearce said.

Assistant Professor Paul Sanders said when he heard about 3-D printing with plastic, he questioned if it could be done with metal.

“This is essentially welding but it’s different because instead of joining two big pieces of metal, we’re making everything out of the weld wire itself,” he said.

America Makes – Michigan Tech Low Cost 3D Metal Printer

America Makes is the National Additive Manufacturing Innovation Institute. They focused on 3D metal printing initiatives at Michigan Tech in the new video “America Makes Moment.” Several people from Michigan Tech were interviewed, including President Glenn Mroz, Associate Professor Joshua Pearce, and Mark Bonefant, Instructor of CAD & Woodworking, Calumet High School. Featured were several students, instructors, and researchers, including Assistant Professor Paul Sanders.

Joshua Pearce coauthored “Design Optimization of Polymer Heat Exchanger for Automated Household-Scale Solar Water Pasteurizer,” published in Designs.

doi:10.3390/designs2020011

The study offers a promising approach to reducing the >870,000 deaths/year globally from unsafe water through the use of flow-through solar water pasteurization systems (SWPs). The high cost of the heat exchanger (HX) is addressed with the introduction of of a polymer microchannel HX as a substitute for coiled copper. The polymer microchannel HX is designed for a 3-D printed collector. The paper focuses on SWP systems fabricated using fully open-source distributed manufacturing.
