Abstract

Articles are produced by the transport of small meltable particles into zones of practically point concentration of heat, resulting in the localised progressive melting of particles to a homogenous mass, the shape of which depends on the motion imparted to the focal point generated by the heat beams. In practice the particles are used to build up into a shape on a base, which is moved rather than the laser, electron or plasma beams at the focal point of which melting is carried out. The method is used for building up components, forming labels on bottles etc.
