The Arcam EBM S400 is a rapid manufacturing and prototyping system that makes 100% solid metal parts. The highly efficient system produces metal parts three to five times faster than other additive fabrication methods. Employing the patented CAD to Metal process, which is based on electron-beam melting (EBM), the system produces parts from titanium powder. In contrast to laser sintering, the electron beam fully melts the metal particles to produce a void-free part. The process occurs in a high vacuum, which ensures the part is completely solid, without imperfections caused by oxidation.
