Bel Air is Arcam’s Choice for Post-Processing of EBM Parts.

Electron beam melting (EBM) is a method of 3D printing and additive manufacturing, in which an electron beam welds together metal powder or wire. This technique produces fully dense metal parts shaped to match the geometry of a 3D CAD model. Arcam EBM, a leading innovator in EBM technology and additive manufacturing, depends on Bel Air’s mass finishing equipment and processes for the post processing of EBM parts.

Metal GE (ARCAM EBM) Samples

We can provide a wide array of surface finish quality to meet your specific needs, as demonstrated in the samples below. Each sample lists the process used to develop the surface finish quality, measured in Ra.

Ra is a unit of measurement. It is the arithmetic average of surface heights measured across a surface, measured in μin.
