E-Rigid PU

E-Rigid PU is a polyurethane-like resin that 3D prints end-use and prototype parts that compete with injection molded plastics.

 Available in black, natural and white, E-Rigid PU is hard and stiff but also maintains good strength, marked by flexibility and impact resistance. With a hardness value of Shore D 80, the same value as a cast urethane plastic, E-Rigid PU is a versatile and tough material.

E-Rigid PU is ideal for end-use and prototype applications that may have previously used ABS, nylon or urethane plastics, such as casings for handheld devices, snap-fit or consumer and sporting goods.
