Principles of PREP technology:

Under the protection of high-purity inert atmosphere, the high speed rotating electrode is arced and melted. The molten metal is atomized by centrifugal force and condensed into a spherical powder in the inert atmosphere.

      Principles of SEBM technology:

      The electron beam quickly scans and melts the pre-formed spherical metal powder on the formed base plate according to the planned path. After completing one layer of scanning and melting, the work table is lowered to a certain height and a new layer of powder is laid. The electron beam scans and melts again according to the path. , Layer by layer, complete the manufacture of metal parts fromTwo-dimensional(2-D) to three dimensional(3-D)  transformation.
