DEVICE FOR SELECTIVE LASER SINTERING FOR PRODUCING A MOULDED PART

摘要

The invention relates to a device for selective laser sintering for producing a moulded part. The inventive device comprises a process chamber (1) having a structural volume (7) for the moulded part (16). Said structural volume (7) is located underneath the floor area (4) of said process chamber. The inventive device also comprises a leveling device for distributing a material in powder form over an area of the floor area of the process chamber in the form of a layer of constant thickness. According to the invention, said leveling device comprises an element (21) which is moved over the floor area in order to distribute said material in powder form. The device further comprises a roller (22) which is embodied as a grinding device by which means the surface of the moulded part to be treated can be smoothed, the moulded part being located in the structural volume. The inventive device prevents wear and tear of the leveling device and ensures that a constant layer thickness is achieved in such a way that components can be produced with better accuracy and better surface quality.
