3Dresyn PEEK-like Polyetheretherketone-like Ultra-Tough Engineering Resin

3Dresyn® PEEK-like is a high-performance engineering photopolymer designed to deliver mechanical behavior comparable to high-performance thermoplastics such as PEEK. It provides very high flexural strength, high stiffness, impact resistance, and excellent chemical and thermal durability.

The material is available in HV (high performance) and LV (low viscosity) versions, enabling compatibility across a wide range of SLA, DLP and LCD systems.

Designed for functional engineering and biomedical applications requiring high mechanical performance, structural integrity and environmental resistance.
