3D printers use less energy than traditional manufacturing

While it makes sense that manufacturing products en masse would be more efficient than manufacturing them one by one, Michigan Technological University researchers found that 3D printing saves on energy because it cuts out shipping and allows users to make objects with less material. Overall, they found that 3D printing cuts down on energy use by 41 to 64 percent.¬†“The bottom line is, we can get substantial reductions in energy and CO2¬†emissions from making things at home,” associate professor Joshua Pearce said in a release.
