Abstract
In a method of building up a component in layers from photopolymerizable material, in particular a resin with ceramic or metallic filler, in which component layers are successively formed one above the other by forming a layer of the highly viscous photopolymerizable material between a building platform or the component and a material carrier, which is cured in a location-selective manner to form the desired shape of the component layer, a cleaning step takes place after the component layer has been formed, in which uncured photopolymerizable material adhering to the component layer is removed by means of a cleaning unit after the component has been lifted.

A method of building up a component layer by layer from a photopolymerizable material, comprising successively forming component layers one on top of the other comprising the steps of:
- forming a material layer of the photopolymerizable material on a material carrier,
- lowering a building platform or the component at least partially built up on the building platform into the material layer, so that a layer of the photopolymerizable material is formed between the building platform or the component and the material carrier,
- curing the layer of the photopolymerizable material in a location-selective manner by irradiation through the material carrier to form the desired geometry of the component layer,
- lifting the component with the component layer,
- wherein the method further comprises carrying out a material removal step after the formation of the component layer, which comprises at least partially removing photopolymerizable material adhering to the component that is not or not fully cured after the component has been lifted by means of a material removal unit.
