EnvisionTEC and Covestro collaborate on material and printer solutions for DLP 3D printing tooling applications

EnvisionTEC and Covestro  announced their collaboration on material+printer solutions to accelerate adoption of industrial 3D printing. Together, the two companies aim to lower the entry barriers for companies looking to adopt 3D printing for producing molds for low volumes or parts with detailed features faster and more economically.

The combination of Covestro material expertise and EnvisionTEC printer technology resulted in a complete industrial manufacturing solution for 3D printing injection mold tooling. Until now, no solution was available that met the stringent industry-required properties in terms of dimensional stability and minimal warpage. The patented material formulation from e-PerFORM™, optimized for EnvisionTEC’s equipment, brings the benefits of Somos® PerFORM to a faster and more economical printer technology.

To bring customers a workable and proven material and printer solution, EnvisionTEC and Covestro optimized print parameters and verified Covestro’s new DLP resin e-PerFORM™ on EnvisionTEC’s Perfactory P4K series printer. EnvisionTEC further tested e-PerFORM™ resin with key molding institutes to validate the material’s performance. Completed mold trials demonstrate that e-PerFORM™ resin, with high stiffness and high temperature performance, behaves similarly to stereolithography resin Somos® PerFORM for injection molding tooling.

Tests confirm suitability for rapid mold making

Tests done by Polyvia, the French Federation of Plastics and Composites, confirm the suitability for rapid tooling. Guy Chrétien, Process project manager at Polyvia confirmed: “We tested the new e-PerFORM™ resin printed on the EnvisionTEC P4K printer and demonstrated that we could achieve very good results in part fidelity and in the number of shots molded in both polypropylene and glass-reinforced nylon. With the cost effectiveness and print speed of the P4k platform and with the properties of the e-PerFORM™ resin, this creates additional opportunities for rapid tooling.” Learn more about their testing on Polyvia’s website.

Al Siblani, EnvisionTEC CEO commented: “The combination of our P4K printer and Covestro e-PerFORM™ optimized for our printers enables fast, cost-effective production of injection molding tooling. Our collaboration has resulted in a new and much-needed solution.”

Hugo da Silva, Head of Additive Manufacturing at Covestro commented: “By working closely with our partner EnvisionTEC, we developed a material that meets critical needs voiced in the market: improved dimensional stability and minimal warpage for optimal functionality. The validation and proven solution with their P4K printers will help accelerate the adoption of additive manufacturing of injection mold tooling.”
