Direct proudction of metallic parts by laserpowder stereo-cladding

摘要

Rapid prototpying techniques ahve recently been developed for idrect production of metallic parts. Among those processin tehcniques suited for the direct production of metallic parts, laser cladding with powder addition is a competent method, whcih offers the advantages ofthigh efficiency, good flexibility, wide suitability, etc. This paper presents the general ideas of alser powder stereo-cladding directly to produce three dimensional metallic parts and describes the used processing system. Some real parts produced with laser stereo-cladding are finally given in the paper.
