Presentation Summary

A key challenge in AM is the printing of high-resolution multi-material ceramic parts. Applications vary from printed teeth to printed casts for jet engines. To address this challenge, TNO developed a machine for large area stereo-lithography. The presentation will give an overview of the novel optical engine and the high-viscosity coating technology.

Speaker Biography (Rik Starmans)

Rik Starmans has a master in applied physics from the Delft University of Technology and a master in Management Technology and Economics from the ETH Zürich. He was involved in the development of the light engine and coater for the Lepus NeXT. For the light engine, he wrote slicer software, programmed FPGA's and helped with the calibration of laser diodes. For the coater, he did a patent study and implemented a blade and an applicator bar in a self-built machine.

Company Profile (Netherlands Organisation for Applied Scientific Research (BMC))
