Somos Taurus Resin

Somos Taurus resin is an extremely durable and high-temperature stereolithography (SLA) material that enables new prototyping and end-use applications. Its core advantages include: superior strength and durability, excellent surface texture and precision for large parts, heat resistance up to 90°C, and performance and feel comparable to thermoplastics. The material is primarily used in functional prototypes, customized end components, automotive components and low-volume connectors in the electronics industry.
