Vitriform3D’s Story: How Glass–an Infinitely Recyclable Material–is Fueling a Startup
Pulled from the Latin word vitri for glass, Vitriform3D is forming new products through 3D printing. With their patent-pending technology, they plan to make coasters, tiles, countertops, even architectural accent walls by embedding recycled glass into 3D printing. It’s a small start-up for now of only Alex Stiles and Dustin Gilmer, who may have never met without IACMI – The Composites Institute. We joke, “All roads lead to Uday Vaidya,” and in this case, it’s true. Dr. Vaidya, Chief Technology Officer for IACMI, was Alex’s advisor during his PhD program at the University of Tennessee, Knoxville (UT). In one of Uday’s many collaborations with outside research groups, Dustin and Alex first worked together on novel methods for 3D printing washout mandrels for composites
So, what gives them hope their startup will succeed? Dustin and Alex have discovered that by reducing glass to a powder, their 3D printed product is more predictable than conventional thermoplastic printed parts. Low expansion and contraction during heating makes it an excellent potential material for autoclave tooling. The binder jetting process can maintain high resolution at large scale, requiring less post-production than a typical large scale thermoplastic 3D print. The finishing process is often what adds considerable time and therefore costs to additive manufacturing. Not here. All that’s left is proving they can scale up for commercialization, which admittedly takes time and money..
