Marcia Goodrich, Michigan Tech It’s old news that open-source 3D printing is cheaper than conventional manufacturing, not to mention greener and incredibly useful for making everything from lab equipment to chess pieces. Now it’s time to add another star to the 3D printing constellation. It may help lift some of the world’s most destitute people from poverty while cleaning up a major blight on the earth and its oceans: plastic trash. At the center of the movement is a new set of...

redOrbit Staff & Wire Reports - Your Universe Online Not only is manufacturing goods using a 3D printer far cheaper than purchasing items, new research appearing in a recent edition of the Journal of Cleaner Production reveals that it can actually help preserve the environment. The 3D printing process was very expensive when Charles W. Hull of 3D Systems Corp created the first working model in 1984, and while the costs have dropped dramatically over the past 30 years, the cost of...

Scientists Build Low-cost 3-D Metal Printer
2013-12-03 14:09:39

Michigan Technological University Key ingredients are steel, a MIG welder, and a microcontroller OK, so maybe you aren't interested in making your own toys, cellphone cases, or glow-in-the-dark Christmas decorations. How about a brake drum? Until now, 3D printing has been a polymer affair, with most people in the maker community using the machines to make all manner of plastic consumer goods, from tent stakes to chess sets. A new low-cost 3D printer developed by Michigan...

3D Plastics Printing Is Greener Than Conventional Manufacturing
2013-10-04 05:21:19

redOrbit Staff & Wire Reports - Your Universe Online A new study finds that 3D printing of plastic products is not only cheaper, but also greener, because it releases less carbon dioxide than producing things en masse in a factory and shipping those products to a warehouse. Michigan Technological University’s Joshua Pearce conducted the study using a RepRap 3D printer designed for home use, which works by melting filament, usually plastic, and depositing it layer by layer in a...

3D Printer Revolutionize Education
2013-07-31 10:48:26

Michael Harper for redOrbit.com - Your Universe Online Twelve teams of Michigan teachers are visiting Michigan Technological University (MTU) this week to get some hands-on experience with 3D printing technology. Here they'll learn about the emerging trend of creating tangible objects from 3D Computer Aided Design (CAD) models and even build their own units to take back to the classroom with them. The workshop is sponsored by GM, PACE (Partners for the Advancement of Collaborative...

3D Printing Can Save Time, Money And Hassle
2013-07-30 04:36:28

Michael Harper for redOrbit.com - Your Universe Online Much of the talk surrounding the so-called revolution of 3D printing is centered around the DIY (or Do It Yourself) aspect, people sharing designs (or creating designs themselves) and then creating them in the comfort of their own home. The DIYers of old may have either taken great pride in using everyday household items and more which they fashioned with their hands or simply chose to do so to earn some extra cash. With some 3D...

Another breakthrough using customizable 3-D printable designs Just as the power of the open-source design has driven down the cost of software to the point that it is accessible to most people, open-source hardware makes it possible to drive down the cost of doing experimental science and expand access to everyone. As part of this movement, a Michigan Technological University lab has introduced a library of open-source, 3-D-printable optics components in a paper published in PLOS One from...

Trash Technology: 3D Printing With Recycled Material
2013-03-05 11:29:40

Lee Rannals for redOrbit.com — Your Universe Online The future of 3D printing is still being determined by researchers in laboratories, and one new project is helping to shape that future, with trash. Michigan Technological University´s (MTU) Joshua Pearce and colleagues are working on a tool for 3D printing called a RecycleBot that turns trash like empty milk cartons into 3D printing material. The tools are open-source, and the mechanical and electrical designs are currently...

The public is being kept in the dark about the viability of solar photovoltaic energy, according to a study conducted at Queen´s University. “Many analysts project a higher cost for solar photovoltaic energy because they don´t consider recent technological advancements and price reductions,” says Joshua Pearce, Adjunct Professor, Department of Mechanical and Materials Engineering. “Older models for determining solar photovoltaic energy costs are too...

Canadian and provincial governments could spend $2.4 billion to build a large scale solar photovoltaic manufacturing plant and then give it away for free and still earn a profit in the long run, according to a financial analysis conducted by the Queen's University Applied Sustainability Research Group in Kingston, Canada. Queen's University Mechanical Engineering Professor Joshua Pearce conducted the study "“ to be published in the August edition of the academic journal Energy Policy...
