Patent abstract

A method for producing a synthetic material part such as, for example, a dental restorative part, is provided and includes spray applying with a spray device a material having at least a polymerizable synthetic material onto a base in succeeding layers. Each layer of the spray applied material is substantially continuously polymerized by the spray device and has a viscosity which permits working of the applied material in an unpolymerized condition thereof with the spray device. The method also includes hardening the one or more of the already applied layers prior to the application of subsequent layers.
