SLA Materials

Stereolithography (SLA) materials produce large, highly-intricate parts with superb accuracy and finishes, making it one of the most popular and widely-used 3D printing technologies in the market today.

SLA materials are best known for their ability to build mostly hollow parts with a thicker outer shell and a honeycomb interior. This can allow for large but lightweight models for a variety of applications, including fully painted display models.

  • Somos® EvoLVe 128 – a durable stereolithography material that produces accurate, highly detailed parts and is designed for easy finishing. The material’s look and feel is almost indistinguishable from finished traditional thermoplastics, making it perfect for building parts and prototypes for functional testing applications and resulting in time, money and material savings during product development.
  • Somos® WaterShed XC 11122 – this material has ABS and PBT-like properties, which makes it a popular resin among designers. Somos® WaterShed produces detailed parts with superior clarity and water resistance, well-suited to fluid flow analysis. The durable, clear parts look and feel similar to an engineered plastic, with a smooth finish that accelerates testing time.


Stereolithography 3D printed parts are the cutting-edge solution for producing high-quality parts with unparalleled surface quality, accuracy, and detail.
