RAPPID PROTOTYPING IN DESIGN AND MANUFACTURE OF PRECISION DEVICES BASED ON ADDITIVE TECHNOLOGY

The features of precision instruments (navigation, medical, measuring, etc.), including the requirements for achieving high accuracy with minimal weight and dimensions, leads to the manufacture of parts with hidden cavities, complex geometry, which requires prototyping. The article presents the results of the analysis and selection of the most appropriate additive technology for the design and production of precision instruments, the preparation of consumables from plastics (photopolymers, polyamides, polystyrenes), metal powders (Titanium, aluminum alloys, etc.), programs managing 3D printers, including the transition from the 3D drawing of the details in the .stl format and through the Slicer by converting to G-Code, the selection of 3D printers, the results of modeling the adaptation processes of additive technology to precision instruments. Advantages of additive technology are shown, especially at the stages of design and technological preparation of production.
