Rapid Manufacturing research at TNO
Frits Feenstra - TNO Science & Industry
ABSTRACT - TNO has a long track record in Rapid Manufacturing research in the area of printing technology. To print other types of materials into products, the process and corresponding equipment have to be modified. TNO develops 3D printers and materials to make this technology applicable for new and exciting applications.
Three areas of research will be addressed:
- Developments in micro-stereo lithography: a system was developed with a build speed of up to 1200 layers per hour, and a resolution of up to 0.025 mm; resulting in 60 mm per hour constructiuon speed.
- High viscosity inkjet development: ink viscosity up to 500 mPa·s in mono and multimaterial application system. The multimaterial functionality and graded structure software will be addressed.
- Metal printing: Direct and indirect printing of metal for applying conductive tracks on substrates. Among others, a specific technology using pyrolytic printing will be addressed.
Biography
Frits Feenstra has a background in Physics and has specific expertise in materials processing (plastics, ceramics) and Rapid Manufacturing by Three Dimensional Printing. At TNO he is currently active as a Senior Project Manager for large (inter)national projects such as CRAFT and EU Collaborative projects. He is and was also involved in setting up international networks in the area of Rapid Manufacturing such as the RM-Platform (www.rm-platform.com). His track record shows co-ordinatorship of RAPTIA thematic network (1999-2003, 32 partners), many Rapid Manufacturing by printing projects for medical, electronics and structural parts sectors. He has 5+ relevant RM patents, contributes to others and he has 20 years of project management at TNO.
