A method of making individual castings. In the production of individual castings, in particular in dental engineering, the casting is usually premodeled in wax. However, this casting model is very susceptible to deformation, which leads to inaccuracies in the fit of the casting. With the present method, at least a part of the casting model is built up from a photopolymerizable compound which burns leaving no residue. Advantageously, the curing is carried out, in the presence of a suitable initiator, with visible light; the basis of the compound is a photopolymerizable (meth)acrylic acid ester. In dental engineering, with the present method there is made possible in a simple manner to build up form-stable casting models for making crowns, bridges, and inlays and, particularly favorably, complicated secondary parts for removable dental appliances.
