Rehabilitation of Working Platforms for 3d Printing Device on Metal

The 3D printing device on metal uses the technological process—selective laser melting, through which dental works with precision and speed can be printed. The dental works are printed on the surface of a metal platform, their attachment being with the help of supports. It is important that this study can rehabilitate the platforms on which the printing is done, by rectification, through several steps, namely: removal of residues (metal supports of dental work), smoothing the work platform with a device that has an abrasive material, washing them under a stream of hot water, so that the grease residues are removed, then keep them in a clean environment.
