Design of a transmissive optical system of a laser metal deposition three-dimensional printer with metal powder

A transmissive optical system of a three-dimensional (3D) printer using the laser metal deposition (LMD) technique with a metal powder is proposed here, together with its design method. An f-number of the focused laser beam emitted from the optical system should be large enough for the laser beam ...
