Stereolithography resin good enough for production
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.
Somos 9110 is a high-speed liquid photopolymer for use on He-Cd laser stereolithography machines that produces robust, functional, and accurate parts.
Wide processing latitude, excellent tolerance to a broad temperature and humidity range during and after build, as well as superior chemical resistance are among the material properties of Somos 9110 which responds to both the prototyper's and the design engineer's needs.
Kevin Dyer, President of Interpro Rapid Technologies, is enthusiastic about the new material which allows the company to utilize the 9100 series also on its SLA-250 machine.
"Our customers' demand for the Somos 9100 series of products continues to grow on a daily basis.
This family of Somos resins offers many advantages which allow the production of prototypes that can withstand a variety of rigorous tests without failing." "This is the first of five new Somos stereolithography products that will be commercialized in the upcoming months," states Charlie Kaufmann, marketing manager of DSM Somos.

Resin ideal for rearview mirror SLA patterns
When Applied Rapid Technologies needed to create prototype aftermarket rearview mirror assemblies, they knew that DSM Somos 9120 would provide the desired properties for the stereolithography patterns
"Somos 9110 differentiates itself from other competitive products by providing a broad process robustness regardless of environmental conditions - a trademark of all commercial Somos resins.
Somos 9110 is also an indication of DSM's commitment to introduce new materials for all stereolithography laser platforms in conjunction with the development of next generation material properties that mimic popular engineering plastics." Somos 9110 is part of the Somos 9100 series of ProtoFunctional materials.
Providing a good balance of properties between rigidity and functionality, these materials are successfully being used in applications where durability and robustness are critical requirements - such as automobile components, electronic housings, medical products, large panels and snap-fit parts.

Stereolithography is a layer additive rapid-prototyping process based on the use of photopolymer liquid resins which solidify when exposed to UV light.
A software program transfers the designer's 3-D CAD model into an electronic file ('STL' format) for stereolithography machines, composing the information into thin cross sections or layers.
A laser beam then traces each layer onto the surface of a vat of photopolymer resin, building the part in repeated layers until a solid replica of the original CAD model is completed.
DSM Somos ProtoFunctional resins range from the industry's first flexible resins for material properties similar to polyethylene (Somos 8100 series) or polypropylene (Somos 9100 series) to the latest generation of heat-resistant, humidity-tolerant, high-accuracy epoxy resins suitable for investment casting and direct tooling applications (Somos 7100 series).
Each family of Somos photopolymer epoxy resins is comprised of materials singularly formulated and optimised for the variety of stereolithography platforms commercially available: Somos XX'00' resins are for use in Argon ion laser systems; Somos XX'10' for Helio Cadmium laser systems; Somos XX'20' resins for platforms utilising Solid State laser systems.
DSM Somos also offers materials for selective laser sintering and is the first manufacturer of powder elastomeric polymer (Somos 201) that can be sintered to produce highly flexible parts with "rubber like" characteristics. Request a free brochure from DSM Somos ...
