Application of additive technology to produce the framework of an electrical drive-flywheel

The purpose of reducing the prime cost and time of manufacture was always timely. The additive technology can be the alternative to the traditional one which uses tools treatment of materials. The first commercial equipment to make products by additive technology was made more than 30 years ago. Due to the termination of the patent restrictions the rapid development of this technology has been observed recently. The equipment operating by the additive technology is called 3D printers and manufacturing process 3D-printing. The application of additive technology can significantly reduce the use of instrumental treatment or completely abandon it. One of the main advantages of the additive technology is the possibility of manufacturing products of complex geometric shape, it can also include internal cavities. Many types of 3D printers were designed; it varies not only by a pressing method, but using materials. In present time it becomes available to print by metal, ceramic and plastic which can be filled with glass or carbon. The framework of electrical drive-flywheel, which is used at orientation system of satellites, was printed to test the additive technology. The printing was done by FDM and SLS printers. The frameworks have been exposed to unfavorable external factors such as vacuum, elevated temperature and humidity. SLS technology of printing by powder of polyamide was identified as the most promising one.
