Abstract
Official abstract text for this publication.
A method and a device for processing light-polymerizable material for the assembly of a mold, utilizing a lithography-based generative manufacturing technique wherein a layer of a light-polymerizable material, the material being located in at least one trough ( 4 ) having a particularly light-transmissive, horizontal bottom ( 6 ), is polymerized by illumination on at least one horizontal platform ( 12 ), the platform having a prespecified geometry and projecting into a trough ( 4 ), in an illumination field, wherein the platform ( 12 ) is displaced vertically to form a subsequent layer, light-polymerizable material is then added to the most recently formed layer, and repetition of the foregoing steps leads to the layered construction of the mold in the desired form, which arises from the succession of layer geometries. The invention is characterized in that the trough ( 4 ) can be shifted horizontally to a supply position, and the supply device ( 8 ) brings light-polymerizable material at least to an illumination field of the trough bottom ( 6 ), before the at least one trough ( 4 ) is shifted to an illumination position in which the illumination field is located below the platform ( 12 ) and above the illumination unit ( 10 ), and illumination is carried out.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for processsing light-polymerizable material ( 5 ; 55 ; 105 ) for building up an object ( 27 ) in layers, using lithography-based generative fabrication, comprising a vat ( 4 ; 64 ; 104 ) with an at least partially transparently or translucently formed horizontal bottom ( 6 ; 56 ; 106 ), into which light-polymerizable material ( 5 ; 55 ; 105 ) can be filled, a horizontal build platform ( 12 ; 62 ) which is held at a settable height…
