|1. (WO2018032022) METHOD AND DEVICE FOR LITHOGRAPHY-BASED ADDITIVE MANUFACTURING OF THREE-DIMENSIONAL SHAPED BODIES|
|Title:||METHOD AND DEVICE FOR LITHOGRAPHY-BASED ADDITIVE MANUFACTURING OF THREE-DIMENSIONAL SHAPED BODIES|
The invention relates to a method for lithography-based additive manufacturing of three-dimensional shaped bodies (11), according to which material (6) that can be hardened by electromagnetic radiation is provided on an at least partially transparent material support, a construction platform (5) is positioned at a distance from the material support, material (6) lying between the construction platform (5) and the material support is heated, and selected portions of the heated material are irradiated and hardened by a first radiation source, the electromagnetic radiation being introduced into the material (6) from below through the material support that is at least partially transparent to the radiation of the first radiation source. The material (6) is heated by means of the irradiation of the material support with electromagnetic radiation from a second radiation source (12), the material support being substantially opaque to the radiation of the second radiation source (12).
