Abstract

In a method for cleaning components with adhering unreacted resin, especially components produced via a lithographic additive manufacturing process, a cleaning step is provided wherein the components are brought into a cleaning chamber (1), the components in the cleaning chamber (1) are contacted with a cleaning medium to detach resin from the components, and the cleaning medium laden with the detached resin is brought out of the cleaning chamber (1), and a regenerating step is provided wherein the laden cleaning medium is passed to a distillation unit (4) in which the contaminated cleaning medium is regenerated by distillative removal of the resin. The cleaning medium is admixed with at least one inhibitor, which prevents polymerization of the resin during the cleaning step and/or the regenerating step.

Abstract

The present invention relates to a metal-filled resin formulation, more particularly for a 3D printing method, on the basis of layer-by-layer photopolymerization for the manufacture of a component, wherein the resin formulation contains a photopolymerizable matrix component, a dense metal filler having a specific minimum volume fraction, and a photoinitiator. A component is additively manufactured by the layer-by-layer selective curing of the metal-filled resin formulation by means of irradiation with light. The invention in particular relates to the high-precision manufacture of radiation-absorbing components on the basis of lithographic additive processes such as SLA; because of the special choice of the formulation used, wall thicknesses down to less than 100 μm are possible while still achieving good radiation hardness and good surface quality.

Abstract

The invention relates to a method for the lithography-based additive manufacture of three-dimensional molded bodies, wherein a construction platform (8) is positioned at a distance from a material support (1), which is permeable at least in some regions to the radiation of a radiation source, for a material which can be solidified under the effect of the radiation. The material support (1) is moved in a translational manner between a first position and a second position. The invention is characterized in that material is deposited with a defined layer thickness during the movement of the material support (1) from the first position to the second position. The applied material is then irradiated and solidified by the radiation source in a location- and/or time-selective manner between the construction platform (8) and the material support (1), and the material is then removed from the material support (1) during the movement of the material support (1) from the second position to the first position.
