A few weeks ago, we introduced you to the British manufacturer Raplas Technologies. The company has focused on resin additive manufacturing, and more specifically, stereolithography, to offer manufacturers reliable, repeatable, and precise solutions. This is exactly what it is continuing to do with the launch of its new machine, the PR 400i. However, it has made some changes to the basic resin technology by taking a closer look at the DLP process, which uses a projector instead of a laser to cure successive layers of resin. This new industrial 3D printer is equipped with a dual projector, combining the advantages of DLP with Raplas’ expertise in stereolithography. But why is the PR 400i so innovative? What are its strengths, and who is it aimed at? We asked Marko Aubel, the man behind this solution, a few questions.
3DN: Can you introduce yourself?

I finished my studies in 2015 and joined Raplas Technologies. It’s one of the first jobs I took. Back then, I was a development and service engineer.
