Environmental Impacts of Distributed Manufacturing from 3-D Printing of Polymer Components and Products Megan Kreiger1 and Joshua M. Pearce1,2 1 Department of Materials Science & Engineering, Michigan Technological University, Houghton, MI, United States. 2 Department of Electrical & Computer Engineering, Michigan Technological University, Houghton, MI, United States. ABSTRACT Although additive layer manufacturing is well established for rapid prototyping the low throughput and historic costs have prevented mass-scale adoption. The recent development of the RepRap, an open source self-replicating rapid prototyper, has made low-cost 3-D printers readily available to the public at reasonable prices (
