Rice University bioengineering researchers have modified a commercial-grade CO2 laser cutter to create OpenSLS, an open-source, selective laser sintering platform that can print intricate 3-D objects from powdered plastics and biomaterials. The system costs at least 40 times less than its commercial counterparts and allows researchers to work with their own specialized powdered materials. The design specs and performance of Rice’s OpenSLS platform, an open-source device similar to commercially available selective laser sintering (SLS) platforms, are described in an open-access paper published in PLOS ONE.
