OpenSLS is a boot-strappable SLS research platform designed to integrate into commercial laser cutters, transforming them into SLS machines.  The  machine is laser-cut acrylic and is assembled with 3D printed parts and easily-procured hardware.  The electronics and software stack is based largely on that of the RepRap Project.  This project emerged from the Advanced Manufacturing Research Institute, with support from Ultimachine, SeeMeCNC, and Taulman3D,  and was continued in Jordan Miller’s Microphysiological Systems and Advanced Materials lab at Rice University.
