A METHOD FOR PREPARING FUNCTIONALLY SPECIFIED MODELS FOR 3D PRINTING

3D printing is widely used in industry, architecture, aerospace, crafts, art, etc. 3D printing based on a variety of materials allows you to create objects from complex heterogeneous materials. However, there are huge computational difficulties. The problem of 3D printing is still open for research. We propose a method for synthesizing objects with a variety of materials for 3D printing. The method supports the procedural evaluation of geometric details and the composition of the material. Functionally defined models provide compact database storage. In the method, only a small part of the final volume is stored in memory, and the output data is transmitted to the output in small portions. The purpose of the proposed work is to create a method for preparing functionally specified models for 3D printing. Additive manufacturing from many materials is becoming available for an increasing number of applications. When developing the proposed method, the following was taken into account. The method provides continuous definition of the material, scalability for printing large volumes and a minimum of preliminary calculations. A method for describing the complex optical and mechanical logic of materials has been developed. The composition of the material and geometric details are calculated procedurally, taking into account the separation of material and geometry. Templates are defined independently of the geometry and are reused in different models. The procedural synthesis of surface and volume detail ensures resolution independence at different image sizes and resolution.
