Our electron beam melting system is an opensource, versatile, and portable additive manufacturing experimental setup ideal for conducting fundamental research or small builds under tunable building conditions. 

Designed with a widely exposed building environment and multiple electrical feedthroughs, it is easy to implement as many metrology systems or close-loop feedback systems as the user desires. With a maximum power of 600W, a building area of 16mm  x 16mm, a maximum scanning speed of 16 m/s, and a focused beam size of 200 micrometers, our machine is capable of handling a wide range of materials and geometries. In addition, the shape and size of the beam are tunable, providing the user with a novel and unexplored e-beam melting condition. The compact structure combined with a large powerful purging system produce a clean and stable inert environment ideal for repeatable and controllable building conditions.
