Greener Solutions 2015: Safer resins for 3D printing with Autodesk

For this challenge, students worked with Autodesk to develop safer and more sustainable resins for 3D printing. The student team assessed the current formulas being used in the industry after being trained briefly in chemistry, toxicology and public health research.  Proposed solutions include: replacing the photoinitiator (using curcumin and riboflavin), modifying acrylate-based resins (with triglycerides or chitosan), and using non-acyrlate resins via pH photoinitiation (with calcite or metal ligand complexes).
