Press Release

Erfurt, Germany – June 15, 2016. Materialise NV (NASDAQ: MTLS), the leading provider of Additive Manufacturing software and sophisticated 3D Printing solutions in the medical and industrial markets, announces at Rapid.Tech its collaboration with Luxexcel, a fast-growing Dutch start-up of customized 3Dprinted optics and of products that require the highest standards of transparency. Together, they will develop a Build Processor tailored to Luxexcel's needs.

Materialise recently introduced the Materialise Magics 3D Print Suite, wrapping all their industrial software solutions into one suite. The Materialise Build Processor is the technology within the Materialise Magics 3D Print Suite that takes care of communication between software and 3D printing machines. Materialise and Luxexcel are now working on a machinespecific, image-based Build Processor for Luxexcel, to give Luxexcel specific control over 3D prints and ensure the quality of optical parts.

Since Luxexcel operates in the optical industry, it's essential to avoid visible printing layers. That's why Luxexcel has developed a unique digital Additive Manufacturing technology that doesn't require post-processing. Luxexcel has previously worked with Materialise to establish a fully automated online ordering process that is completely streamlined with 3D Printing production.

"Materialise software helps us to support our 3D printing technology for optical products,"says Hans Streng CEO Luxexcel. "By implementing the Build Processor we will get a tailored solution which supports seamless communication between software and our 3D printer for our prototyping business. It contributes to the growth of our 3D printing service and supports new technological developments."

Materialise and Luxexcel look forward to the release of the Build Processor. Visit Materialise at hall 2. 412 at Rapid. Tech to get more information about the Build Processor technology. More information For more information on the Materialise Build Proce
