EOS has added a black mass-colored nylon 11 to its portfolio for use with its laser sintering machines.

Germany’s EOS (U.S. office in Novi, Mich.) has launched a black mass-colored nylon 11 for use with its Formiga, EOS and Eosint laser sintering additive manufacturing machines. Designated PA 1102 black, the material is made from renewable resources as is the case with the company’s PA 1101 natural colored nylon 11, introduced in 2012. Both materials are said to be opening up new applications and boast high impact resistance, resilience, and flexibility.

            Due to its color, parts made with PA 1102 black are resistant to dirt or discoloration under most extreme conditions. Parts made with the material reportedly will not split even under excessive load conditions, owing to its excellent mechanical properties. It is said to be a perfect fit for serial parts, highly-stressed functional models, as well as design prototypes.

            Among EOS’ pilot customers during the material’s development was Accurate Technologies Inc. (ATI), Wixom, Mich., a manufacturer of electronic control unit development tools for the automotive and other vehicular industries. Last year, the company teamed with EOS to help develop and refine the PA 1102 black nylon 11 material, according to Mike Schuch, head of Accurate’s Mechanical Engineering & Machine Shop. “This material is Accurate’s primary material and the basis for several ATI products, the first of which was the CANary Interface Module. We’ve been very happy with the results. The material gives us the ability to produce innovative products that are enclosed in equally innovative designs that are custom-fitted to our products without compromising strength, durability, and good looks. We look forward to releasing many more products in the future with this very effective combination.”

            Meanwhile, natural-colored PA 1101 is now being applied in a number of serial applications. Established biocompatibility and food-grade approvals carries out (e.g., cytoxicity according to DIN EN ISO 10993-5) and all have been successful based on part examination. As a result, there is a growing interests in the material from the medical and food industry, according to EOS.  (248) 306-0143 •
