Modern foundry technique can also start with 3D computer files instead of a model or pattern. Objects can be designed completely with computer software and then with the appropriate 3D file, a rapid prototyper can build the object in a variety of materials, usually plastic. The design potential and accuracy of this modern method is phenomenal. We work with 3D files and rapid prototypers and they are necessary to produce accurate or production no-wax models.
