ADDITIVE MANUFACTURING APPARATUS

摘要

Additive manufacturing apparatus for successively exposing a plurality of layers of photo-reactive substance to form a build comprises a build support to support the build and a light transmissive member for transmitting light to photo-reactive substance in a layer. At least one of the light transmissive member and the build support is movable relative to the other to vary a selected region of a layer during exposure of the layer such that the position of the light transmissive member determines the thickness of the selected region.
