Somos® PerFORM

A fast processing stereolithography material resulting in strong, stiff and
accurate parts with high feature resolution

Somos PerFORM Material Properties

Behaviour and use

Material Overview

Somos® PerFORM produces strong, stiff, high temperature resistant composite parts that are ideal for tooling and wind tunnel testing applications.

With the lowest viscosity of any composite stereolithography material, parts made from Somos® PerFORM are faster to build, easier to post-process clean, possess superior sidewall quality and provide unmatched detail resolution. It is the ideal material for creating strong, stiff parts with excellent high heat resistance, including wind tunnel models for aerospace and automotive applications, as well as rapid tooling for injection molding.

Key Benefits

  • Excellent detail resolution
  • Fast, easy processing & finishing
  • Superior high heat tolerance

Ideal Applications

  • Tooling
  • Wind tunnel testing
  • High temperature testing
  • Electrical casings
  • Automotive housings

Stereolithography (SLA) Technology

Advantages of 3D printing Somos PerFORM with a Stratasys Machine

What is Stereolithography?

Stereolithography (SL/SLA) was the world’s first 3D printing technology, and it remains a great option for highly detailed prototypes that require tight tolerances and smooth surfaces. It uses a UV laser to cure and solidify fine layers of photopolymer in an open vat.

Why choose SLA?

SLA is great for prototyping parts that will ultimately be painted or coated because the models can be finished using the same materials and processes as the end product. Transparent, heat resistant and moisture resistant materials are also attractive for medical, automotive and other prototypes that call for flow visualization, light transmittance or thermostability.

SLA benefits

Product designers opt for SL models when a quick build time is crucial, and they can invest time and resources into additional finishing processes. SL can also produce master patterns for urethane casting, and investment casting patterns that are used to produce metal parts for aerospace, automotive, power generation and medical applications.
