CSEM is a privately held, R&D center established in 1984 in Neuchâtel, Switzerland. From the beginning, CSEM has been committed to both applied and order-related R&D. This bridge function between economics and science is still a core aspect of the company, and CSEM has continuously adapted its research areas to the needs of industry.

The picture shows a 3D printed metal part with channels of 1mm diameter. Additionally the channels were flow polished for improved surface roughness and cleanliness. A number of UNF-threads have been printed on top of the fluid channels to allow fast connection of bottles and filters to ultimately perform a sample preparation procedure of a liquid solution before being analyzed on a photonic bio-chip.

3D printing in steel is used for rapid prototyping but also for small series production. At CSEM we do the designs and evaluation but outsource the manufacturing and post-processing task to our partners.
