Product Description
XTC-3D™
XTC-3D™ is a protective coating for smoothing and finishing 3D printed parts. Two liquids are mixed together and brushed onto any 3D print. Coating self-levels and wets out uniformly without leaving brush strokes. Working time is 10 minutes and cure time is about 4 hours (depending on mass and temperature). XTC-3D™ cures to a hard, impact resistant coating that can be sanded, primed and painted. Adding colors and metal effects is easy.
Alja-Safe™
Safe to use Alja-Safe™ is the world’s first alginate molding powder that does not contain crystalline silica (a known carcinogen). Alja-Safe™ is perfect for making single-use molds of the face, hands and other body parts. It captures detail better than other alginates, giving you a more accurate reproduction of your original.
Certified Skin Safe - Material is skin safe and certified by an independent laboratory.
