With the addition of Stereolithography (SLA) as a 3D printing technology at Xometry, we have more than doubled our additive material offerings. We also offer the largest selection of industrial SLA materials in the country to prototype and produce your parts.

SLA is known for its high accuracy, durability, and great surface finish. These are the top materials our customers return to time and again depending on their needs:

Impact Resistance

Certain SLA materials create very durable parts, which are ideal for rough or busy environments. These materials are especially known for their durability:

Accura Xtreme White


Accura Xtreme White

This is a very tough SLA material similar to polypropylene or ABS. It is widely used for snap enclosures and is available in the color white. We also offer the material Xtreme Grey, which has the same properties in the color grey.

Somos NeXT


Somos NeXT

This material is extremely durable and polypropylene-like. As one of our most popular options, it offers high versatility and is available in the color white.

Opaque Black

SLA parts are known for their superior level of detail and high definition surface finishes. However, there are limited options on the market for dark colored SLA materials. At Xometry, we can offer you a few options that will give your parts a natural dark cosmetic appearance:

Accura ABS Black

Accura ABS Black

A durable ABS-like SLA material with an exceptional black finish useful for parts designed for injection molding. It is available in the color black.


Somos Taurus

An impact resistant ABS-like material that exhibits a great balance of thermal and mechanical performance. It is available in the color charcoal grey.

Highly translucent or clear

In addition to colored surface finishes, Xometry offers numerous translucent or clear options for specific cosmetic needs. Transparent SLA materials are naturally clear, but there will be limitations due to layering inherent with the process. As-built, you can easily see colors through the parts, but may not be able to read text. If optical clarity is needed, we offer options for secondary finishing depending on the application. These are our top clear materials:

Somos WaterShed


Somos WaterShed

A naturally transparent, ABS-like material, with excellent moisture resistance. The material exhibits high clarity with secondary finishing. It is available as a translucent clear finish.
