We started by filing a patent in 2015 on using additive manufacturing for composites production. The patent describes how a printed part is co-cured with a composite to form an integral structure. Obviously this required a tremendous amount of research and experiments to get it working right.
Most important for us was to set-up the company to be able to produce large parts using our technology; there is no real benefit in building only small or very fragile parts. No, we wanted to produce real life composite parts, meaning high strength and large dimensions.
This meant we had to develop a printer that could work with large dimensions and materials that fit the requirements of the composite market, both from a property as well as cost perspective.
Our first prototype printer already had significant printing volume, but was hacked together to show the principle and idea. This worked very well and it learned us a lot about the requirements of a full size machine.
The first printer with a build volume of 0.5 x 0.5 x 1m was constructed and further optimised in the year after. After a lot of small modifications in both hardware and software we now have a machine with very level control below 10 mu and scaleable layout.
Next to the machine also the resin system has seen continuous development and in the coming months we will announce our new resin systems to even better suit some of our customer’s applications. Having resin development capability in house also allows us to optimize our products to a specific application.
