The present paper deals with a new method of RP from metal powders. The process is divided into two steps. First, metal powders are sintered by CW laser with the aid of an electric heater. This can reduce the warp generation in the sintered plate. Next, the sintered objects are united into one by pulsed laser melting and welding. Examples of formed objects are exhibited.
