Abstract: 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. 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.

Abstract: The invention relates to a device for sintering, removing material and/or labeling by means of electromagnetically bundled radiation, especially to a laser sintering machine and/or a laser surface-processing machine. Said device comprises a construction space (3) which is accommodated in a machine housing (2) and in or above which the following are located: a light-guiding device, especially a scanner (4), into which the beam of a sintering energy source is coupled; a vertically displaceable workpiece platform (7); and a material supply device comprising a coater (9) for supplying sintering material from a supply container (8) to the process area above the workpiece platform (7). Said workpiece platform (7) is a changeable element which can be removed from the construction space (3).
