Whether you’re looking to leverage parts for long-term use or elevate your prototyping capabilities, Formlabs Polyurethane Resins are designed to withstand extensive testing and perform under stress.

Choose PU Rigid 650 Resin for pliable, tough, and impact-resistant parts that can maintain dimensional accuracy under stress.

Polyurethane Resins have a longer workflow requiring additional equipment and set-up costs. More attention is needed when setting up prints and post-processing parts to get consistent, high-quality results.

Supports print resolutions: 100 µm and 50µm on the Form 3(B)(+) and Form 2.
