Somos NeXt Material Properties

Behaviour and use

Material Overview

Somos® NeXt is a highly durable stereolithography material which produces very accurate parts with high feature resolution.

This material is ideal for the production of tough, complex parts that also exhibit excellent moisture and thermal resistance. Somos® NeXt has a look and feel that is almost indistinguishable from finished traditional thermoplastics, making it perfect for building parts and prototypes for functional testing applications — resulting in time, money and material savings during product development.

Somos® NeXt is an outstanding material for industries such as aerospace, automotive, medical, consumer products and electronics.

Stereolithography (SLA) Technology

Advantages of 3D printing Somos NeXt 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.
