Formlabs Durable Resin V2.1 is a wear-resistant engineering resin for the Form 4, updated to take full advantage of the printer's MSLA light engine. It exhibits polypropylene-like properties - low friction, good flexibility, and strong resistance to repeated wear - making it one of the most versatile engineering resins in the Form 4 lineup.

Durable V2.1 is ideal wherever parts must withstand rubbing contact, repeated assembly and disassembly, or surface wear over time. Enclosures with integrated clips, consumer product housings, wear test specimens, and snap fit mechanisms all benefit from its combination of flexibility and durability. The updated V2.1 formulation ensures reliable curing consistency with the Form 4, producing parts with predictable mechanical behavior across the build volume.

Key features

• Polypropylene-like low friction and wear resistance, suitable for sliding contact and repeated assembly.
• Updated V2.1 formula optimized for the Form 4 light engine, ensuring consistent curing and mechanical properties.
• Good flexibility without brittle failure, suitable for snap fits and clip mechanisms.
• Excellent surface finish that reduces friction in contact applications.
• Well suited for consumer product enclosures, functional housings and wear-test components.
• Resists deformation under moderate mechanical loads, balancing stiffness and ductility.
