Additive Manufacturing

Somos® DMX SL-100 for hollow composite tooling. Creating structural impact.

Creating intricate, hollow composite parts has always been a challenge for the traditional manufacturing industry – but not for additive manufacturing. Somos® DMX-SL™ 100 is a durable and tough stereolithography (SL) material that enables you to produce 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.

Somos® DMX-SL™ 100 is a unique material for creating 3D printed sacrificial tooling for a wide range of applications, from automotive parts to consumer products to electronics and healthcare. It 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.

But where it really breaks the mold is in the speed, efficiency and design freedom it brings. It’s all based on a unique ‘dry removal’ process that enables mandrels to be removed from complex and convoluted geometries after the autoclave without the need for submersion in caustic (which can affect the composite part).

As a result, manufacturers have more design freedom to create high temperature, cost-effective tools in days rather than weeks or sometimes even months.
