Somos® EvoLVe™ 128

Somos® EvoLVe™ 128: Durable Stereolithography Resin

Somos® EvoLVe™ 128 is an advanced stereolithography (SLA) resin that produces defined, accurate parts for functional applications. It is engineered to deliver performance that is almost indistinguishable from finished traditional thermoplastics, providing a reliable solution for demanding product development and manufacturing environments. Its key differentiator is the combination of high-detail printing with durability and an easy-to-finish surface.

Mechanical Performance and Durability

This material offers a strong balance of mechanical properties, including high tensile strength (56.8 MPa) and stiffness (2,964 MPa), making it suitable for parts that must withstand functional testing and use. With excellent impact resistance and an elongation at break of 11%, it is a reliable choice for creating durable components, including parts with snap-fit features and living hinges.

Design, Processing, and Finishing

Designed for use with 355nm SLA systems, Somos® EvoLVe™ 128 is valued for its user-friendly processing and finishing characteristics. Parts are produced with a clean, exceptionally smooth surface finish that significantly reduces the need for manual post-processing. This allows for faster deployment of parts into industrial workflows, from tooling to end-use components, saving both time and labor costs.

Lifecycle: From Functional Prototypes to Jigs & Fixtures

Somos® EvoLVe™ 128 is ideal for creating high-fidelity, functional prototypes that accurately simulate the performance of end-use products. Its dimensional stability and durability also make it an excellent choice for producing custom manufacturing aids such as jigs and fixtures, where precision and long-term reliability are critical for operational efficiency.
