Stereolithography Resin
For semi-flexible parts that exhibit strong memory retention.
The need for movable parts is a constant when it comes to prototyping. Being able to ensure the proper fit for parts within a component can save both time and money. Whatever industry or application, Somos® 9120 provides the ultimate solution for form, fit and function with parts that are semi-flexible.
With mechanical properties that mimic many engineering plastics, parts created from Somos® 9120 exhibit superior fatigue properties, strong memory retention and a good balance of properties between rigidity and functionality.

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.
