DSM Somos Introduces DMX-SL 100

By DE Editors

DSM Somos (Elgin, IL) has introduced DMX-SL 100, an SL resin targeted at high-durability applications. DMX-SL is based on a new technology that produces resins with extremely high impact strength and resistance to breakage.

"DMX-SL is very different from traditional SL resins," says Somos Product Development Manager Brian Bauman. "With an impact strength up to 0.80 Jpcm, yet a flexural modulus ranging from 2000-2400 MPa, it has the stiffness of standard ABS-type resins but with more than twice the impact strength-plus up to 20 percent elongation at break."
 
The company says this closer approximation of thermoplastic properties brings stereolithography one step closer to direct manufacturing. This would result in the cost-effective direct building of custom plastics parts without the need for tooling. Though stereolithography has successfully been used to date for some specific direct manufacturing applications (e.g., hearing aid shells, jigs and fixtures for product assemblies, and interior products such as custom lamp shades), its widespread use has been restricted to products that do not require much durability.
