Forming device for thermomagnetic treatment in selective laser melting

摘要

The utility model relates to the design of a device for the additive production of three-dimensional products by the method of selective laser melting or sintering, in which additional heat treatment and magnetic field treatment are carried out directly in the device for additive manufacturing, which can contribute to both increasing productivity and improving the properties of the resulting products. The model consists in the fact that a forming device for thermomagnetic processing in selective laser melting, including a chamber for processing a layer of powder and a base in the form of a pipe with a heated platform located in its cavity, contains a magnetic system made in the form of at least one inductor , installed with the possibility of reciprocating movement relative to the bath with powder material and covering the outer side of the pipe and chamber walls. The technical result of the utility model is that the use of a system of magnets in the form of coils with the possibility of reciprocating motion allows for thermal and magnetic treatment without the use of additional equipment and to form a uniform magnetic field both in the treatment zone of the layer and in the entire volume of the powder bath, which makes it possible to obtain materials with a homogeneous or selective inhomogeneous structure and properties with a minimum of structural defects. 2 d.p. f-ly, 1 dwg.
