Stereolithography Resin
Breaking the mold in speed, efficiency and design freedom.
Somos® DMX-SL 100 is a durable and tough stereolithography material that enables production of complex, hollow composite parts in days thanks to a unique and cost-effective ‘dry removal’ process – and all with no compromise on quality and aesthetics.
The ‘dry removal’ process enables mandrels to be removed from complex, convoluted geometries after the autoclave without the need for submersion in caustic (which can affect the composite part). Somos® DMX-SL 100 produces very accurate parts with a superb surface finish and outstanding feature detail. Somos® DMX-SL 100 withstands the extreme temperatures of the autoclave process utilized in composites manufacturing, maintaining its flexural strength, elongation and tear resistance.
As a result, TriMech can provide you with more design freedom to create high temperature, cost-effective tools in days rather than weeks or sometimes even months.

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.
