Innovative Resins Lead a New Generation of
SLA Possibilities

Technology is blazing a trail when it comes to the selection of materials available for today’s rapid prototyping solutions. Parts made with exceptional accuracy, outstanding stability and high heat deflection values are not only possible, they are now being produced with record turnaround times.

Leading the way among these innovative materials are the latest SLA resins from DSM Somos®, which include ProtoGen O-XT™ 18120 and 18420. These resins are based on DSM Somos®’ Oxetane Advantage™—a material technology that develops parts with faster photospeed, higher green strength and better resistance to moisture.

For precision, ProtoGen O-XT™ 18120 and 18420 are tough to beat. The materials deliver extremely high accuracy during builds due to very low differential shrink. ProtoGen resins exhibit linear shrinkage of less than 0.001 inch—a value typically only seen in highly-filled composite resins.

Finished parts can be drilled and tapped without breakage, making further improvements in accuracy and design flexibility possible during post-machining. Because ProtoGen materials produce excellent sidewall quality, less secondary finishing is required to remove layer lines—a valuable cost-savings benefit.

Another standout is the DSM Somos® 9420 EP-White, which combines the mechanical performance of polypropylene with an aesthetic similar to white injection-molded materials. The resin is strong, resilient and less likely to snap compared to other materials when performing function testing. Its flexibility makes it useful for many applications including, snap-fit parts and hinges.

In 2006, DSM Somos® designated Laser Reproductions as an exclusive provider of the complete line of DSM Somos® ProtoFunctional® resins, allowing Laser to provide the largest offering of the materials from a single source among service bureaus in the United States.

Laser Reproductions has extensive experience with a variety of processes and a vast selection of materials to accomplish your rapid prototyping, manufacturing or product development project. Call 614.552.6905 to learn more.
