Abstract
A polymerization apparatus includes a first chamber and a second chamber and a flexible, radioparent diaphragm separating the first chamber from the second chamber. A radiation source emitting polymerization-inducing radiation into the first chamber is provided. The second chamber is adapted for receiving a model and a foil, positioned between the diaphragm and the model, to be subjected to the radiation of the radiation source. A device for generating a pressure differential between the first and the second chamber for deflecting the diaphragm toward the model to thereby deform the foil at the model is provided. An adjusting device for adjusting the distance between the model and the diaphragm is provided.
Claims16
A polymerization apparatus comprising:
- a first chamber and a second chamber;
- a flexible, radioparent diaphragm separating said first chamber from said second chamber;
- a radiation source emitting polymerization-inducing radiation into said first chamber;
- said second chamber adapted for receiving a model and a foil, positioned between said diaphragm and the model, to be subjected to the radiation of said radiation source;
- a device for generating a pressure differential between said first and said second chamber for deflecting said diaphragm toward the model to thereby deform the foil about the model;
- an adjusting device for adjusting a distance between the model and said diaphragm;
- and pressure-stable filling bodies positioned approximately laterally of the model to reduce deflection of the diaphragm as the foil is being deformed about the model.
