DSM Somos announces the release of the second member of the DSM Somos 9100 family of resins, Somos 9120, for use with solid state laser equipped stereolithography machines.
The Somos 9100 series-designed to mimic polypropylene's tensile strength, elongation at yield and Young's modulus-offers enough durability to allow functional prototyping but also the rigidity and robustness required to survive the RTV tooling process.
Parts made with Somos 9100 series resins exhibit superior performance as prototypes and patterns, and, for the first time, can substitute for injection-molded parts in short run production applications.
Somos 9100, optimized for the Argon ion laser, was announced earlier this year.
DSM Somos' global commitment to market " best in class " resins for stereolithography was evidenced by an extensive beta test program designed to ensure trouble free performance in commercial use.
Beta tester Dave Flynn of Express Pattern notes, "With its wide process latitude and excellent toughness and flexibility, Somos 9120 is a winner-the most significant improvement in resins for the solid state laser platform since the introduction of epoxy resins for stereolithography." Recognizing recent advances in solid state laser technology and expanding relationships with international stereolithography equipment manufacturers and distributors, the Somos 9120 resin was evaluated across numerous platforms.
This product optimization program, spanning operations in the U.S., United Kingdom, Switzerland, Belgium, Germany and Japan included evaluations on 3D System Corporation's SLA-7000, SLA-5000 and SLA-3500; SLA-250 and SLA-500 machines modified with DPSS solid state laser upgrade, the European Stereos machines, and Sony stereolithography equipment (sold in Japan by DMEC).
Official domestic beta sites included Scicon Technologies (Valencia, CA), Dynacept Corporation (Brewster, NY), Express Pattern (Buffalo Grove, IL) and the US Army (Aberdeen, MD).
"We are well pleased with the unprecedented success of the 9120 beta testing, emphasized by material orders from test sites for use on one of their other systems prior to the conclusion of the testing," said Jim Reitz, DSM Somos Business Manager.
