Apparatus for producing three-dimensional objects, has plug-in projection that is connected in screw-free form-locking connection manner, such that fixation takes place between upper portion and plate-like portion in z-direction

摘要

The apparatus has an irradiation device that is provided for irradiating the coated layers of material at cross-section of object. A releasably attached pad (4) is provided on a carrier (5) which is arranged at an underside of plate-like portion (15). A plug-in projection (18) is fixed on an upper portion (14) in XY-plane, and is arranged between the upper portion and plate-like portion in z-direction. The plug-in projection is connected in screw-free form-locking connection manner, such that fixation takes place between the upper portion and plate-like portion in z-direction.
