DEVICE FOR SINTERING, REMOVING MATERIAL AND/OR LABELING BY MEANS OF ELECTROMAGNETICALLY BUNDLED RADIATION AND METHOD FOR OPERATING THE DEVICE

摘要

The invention relates to a device for sintering, removing material and/or labeling by means of electromagnetically bundled radiation, especially a laser sintering machine and/or a laser-surface processing machine, especially for carrying out stereolithographic methods. The device comprises a construction space (3) which is accommodated in a machine housing (2) and in which the following are provided: a scanner (4), into which the beam (5) of a sintering laser (6) is coupled; a vertically displaceable workpiece platform (7); and a material supply device comprising a coater for supplying sintering material in powder, paste or liquid form to the process area above the workpiece platform, from a supply container. Said scanner (4) is arranged on a scanner support (8) which can be displaced by a motor over the workpiece platform (7) in the manner of a cross-slide. Driving motor elements of the scanner support (8) are connected to a control computer (9) of the device (1) and are controlled by the same during the construction process in order to move the scanner (4) over the workpiece platform (7).
