An experimental process, Shapeways’ glass 3D printing, uses recycled soda-lime glass. Glass powder is sintered—heated until it sticks together but doesn’t melt— then fired in a kiln. The end result is an opaque, white and fragile glass material that is the basis of all of Shapeways’ glass 3D printing. Milky white matte glass is the default, but the glass can be enameled for a glossy finish in black or white.
Designs made using glass 3D printing can be purchased at Shapeways or can be uploaded for individualized production.
