The possibility to manufacture the experimental models and ready articles from metal and composites, is a result of laser technolo gy (sintering or cladding) and information technology mutual integration [1]. Naturally, at laser Rapid Prototyping* technique development the different schemes of processing (like in a basic technology) may be utilized: melting (sintering) of a preformed layer of a powdered material [2] or its immediate feeding into a zone of laser interaction with material [3]. Each of the schemes has the advantages and lacks. So the advantage of the first method is the possibility of sintering of the ultra disperse powdered material in a solid phase, and the lack appears at forming the “hollow” details, as the powder fills the whole volume and it is necessary to provide the technological windows for its removal. This disadvantage is absent at the second method of processing – the amount of the powdered material which occurred inside the hollow details is minimal. Common for all systems of Rapid Prototyping is:

  • High level of mutual integration;

  • Preparation of a drawings of the designed article with the help of CAD system;

  • Manufacture of an article via “layer by layer” technique;

  • Dependence of outcome of processing on conditions of irradiation, properties of a powdered material etc.

This paper is devoted to a problem of technology and equipment for Rapid Prototyping development.
