CITC and AMSYSTEMS combine expertise to accelerate 3D printing innovation

April 26, 2021 – CITC assisted AMSYSTEMS in validating future production technology that is needed to assemble the exposure module.

Innovative additive manufacturing

AMSYSTEMS is a technology provider for innovate additive manufacturing technologies. It has developed unique methods to disruptively fasten the speed of 3D printing. This includes a transparent polygon-based light engine for SLA (Stereo Lithography Apparatus) printing processes. The light engine speeds up exposure of resin via interconnected modules, each containing 20 laser diodes. Using this method, it is possible to produce a large number of products in a faster and more cost-effective way, without compromising on product quality.

Proof of principle analysis

Roeland Brugman, CEO and founder of AMSYSTEMS, explains the cooperation: “Our light engine is an exposure method based on Blu-ray laser diodes. We needed insight in the possibilities of using active alignment for lens to diode positioning and bonding. CITC was able to do a proof of principle analysis to check whether it is feasible to align and bond a micro lens in front of a laser diode with μm accuracy. It would be a huge improvement if it could be done automatically instead by manual calibration.”

Experimental set-up

CITC’s Senior Micro-Electronic Packaging Engineer, Sander Dorrestein performed an assembly process flow by using an experimental set-up. At the end, the experiments showed that it indeed is possible to use active alignment. Sander clarifies: “First, it is possible to manipulate the lens in all six degrees of freedom. Second, it is also possible to calibrate the focused spot. And finally, it is possible to assemble the lens onto the cooling block with minimal displacement. The first results are very positive. However, more experiments are recommended to indicate process stability and repeatability.”

Multidisciplinary expertise

According to Roeland working with CITC confirmed his earlier experiences: “By combining technologies of several domains you get multidisciplinary expertise that accelerates innovation. In this case, CITC’s expertise in high complexity, extreme precision modules and cooperative, open mindset enabled things that seemed to be impossible. This way of working together demonstrated itself as very valuable.”

CITC is proud to have been able to contribute to AMSYSTEMS’ mission to fasten the speed of additive manufacturing. Interested in working with CITC too? Contact Marco Koelink, Business Development Manager
