Abstract: The present invention relates to an additive manufacturing apparatus for additively manufacturing a component including: a resin vat unit which includes: a reservoir for storing UV-light photocurable resin; and a frame assembly holding a UV-transparent window at the bottom of the reservoir, said UV-transparent window includes a UV-transparent plate and a UV-transparent anti-adhesive flexible foil; a projection unit for projecting UV-light through the UV-transparent window into the reservoir; and a movable building platform having a surface onto which said component can be formed through layerwise curing of said resin. The UV-transparent window further includes a removable frame-like spacer foil which has a predetermined thickness and can be removably mounted by means of the frame assembly between the UV-transparent plate and the UV-transparent anti-adhesive flexible foil in order to create a plate-foil air gap; and at least one air hole for communicating said plate-foil air gap with the atmosphere.

Abstract: The invention relates to a sintering furnace (1) for components (15) made of a sintered material, in particular for dental components, comprising a furnace chamber (2) having a chamber volume (VK), wherein a heating device (5), a receiving space (9) having a gross volume (VB) located in the chamber volume (VK) and delimited by the heating device (5), and a useful region (10) having a useful volume (VN) located in the gross volume (VB), are disposed in the furnace chamber (2). The furnace chamber (2) has an outer wall (3) consisting of a plurality of walls having a wall portion (7) to be opened for introduction of a component to be sintered having an object volume (VO) into the receiving space (9). In the furnace chamber (2) the heating device (5) has a thermal radiator (6) having a radiation field (13) which is disposed on at least one side of the receiving space (9). At least the useful volume (NV) disposed in the receiving space (9) is disposed in the radiation field (13) of the radiator (6), wherein the maximum possible distance (d) of the component (15) to be sintered from the radiator (6) corresponds to at most twice the dimension (Dy) of the maximum useful volume (VN).
