Cristian Sion, a senior at Cal Poly SLO, decided that he wanted to help local front line workers…by making masks with a 3D printer! Amazing! The manufacturing and materials engineering major partnered up with an a facilities engineer at SLO Surgery Center and an emergency room doctor to create the respirators.

Sion spent several months designing these masks, and now makes them in his garage! There is even evidence to prove that his masks may be more effective than many non-surgical masks sold in stores.

Brilliant work, Cristian!
