Somos PerFORM Reflect

Stereolithography Resin

Very high heat and stiffness, ceramic, developed for Particle image velocimetry (PIV).

Somos® PerFORM Reflect utilizes patented new technology that reduces and can even eliminate the finishing work required by traditional materials. Somos® PerFORM Reflect produces strong, stiff, temperature-resistant composite parts ideal for wind tunnel testing.

By eliminating the need for additional PIV coatings, Somos® PerFORM Reflect reduces post-processing by more than 30%. Decreasing the overall lead time per design iteration and allowing clients to conduct iterations faster leads to faster data collection.

Stereolithography (SLA) Technology

Advantages of parts built with a Stratasys Stereolithography 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.
