Production object layer (LOM) is one of the methods of rapid prototyping is. The plan has been prepared with the CAD unit control system LOM to enter. In this system, the form of the cross section work piece in a layer set and this form by the laser beam on the material that for a roll to the laser beam driven, etc., will be cut. Other parts of the level also to the cross by the laser beam cut is given that after the complete three-dimensional model, etc. can be waste material from the main model separated. The layer that is to form hanging can be cut into layers of coarser stick, then a new layer is notched, and to the previous layer to stick. This operation automatically, so repeated that all the layers are cut to stick together. Part of hairy from the original model separated to form its final appearance crafted. Level final model can be sanding pounded, rendered and painted him.
