Tough 1000 Resin
SLA · Engineering photopolymer · Grey (dark, matte)
A flexible, impact-resistant material whose toughness competes with high-density polyethylene (HDPE). It is intended for parts that need exceptional strength, toughness and resistance to wear and fatigue, and has a matte dark grey finish.
