Somos DMX SL 100 Data Sheet

Fast and easy production of quality hollow composite tooling parts, that are easy to remove after the autoclave process.

While basic composite shapes with constant cross sections are easily manufactured using traditional composite manufacturing techniques, complex parts with hollow interiors present a unique challenge. Additive manufacturing has fundamentally changed the process. High-temperature, cost-effective tools can now be produced in days, compared to the weeks or even months required for traditional tooling, and provides a cost-effective solution even for small series production.

Somos® DMX SL-100, a durable and tough stereolithography (SL) resin, is an efficient and cost-effective solution that produces very accurate parts with a superb surface finish and high feature detail, promoting greater design freedom for composite applications.

Somos® DMX SL-100 withstands the high temperatures utilized in the autoclave process for composites manufacturing maintaining its flexural strength, elongation and tear resistance. These unique properties allow, at a certain temperature, for mandrels to be removed from complex and convoluted geometries through a “dry removal” process which is unique for a solid mandrel. Other soluble wash out cores need submerging in caustic which can affect the composite part. No other material in the industry is as easily and best removed after the autoclave process, facilitating the more efficient production of complex, hollow composite parts.

This method of using additive manufacturing to produce sacrificial tooling is straightforward and enables multiple iterations to be implemented quicker by the user.
