DEVICE FOR MANUFACTURING OF THREE-DIMENSIONAL OBJECTS

摘要

A print head for a manufacturing device for manufacturing a three-dimensional object (8) by the stepwise curing of layers of building material comprising a material depositing unit (2) ejecting building material on a surface (4) or previously deposited layer and a radiation source for curing deposited material on the manufacturing surface (4). The print head (1) is arranged moveable relative to the manufacturing surface (4). The radiation source is realized by an electron beam emitting unit (3) comprising a vacuum sealed casing (11) housing an electron beam source. The print head (1) is advantageously designed as a modular system at least comprising the depositing unit (2) and the electron beam emitting unit (3), wherein the electron beam emitting unit (3) is exchangeable.
