Industrial Automatic Control Systems and Controllers Annotation << Back The use of Digital Technologies and Innovative Additive Capabilities in Education for the Production of Architectural Models of Buildings, Structures and Building Structures Kokorev B.S., Zabelina S.A., Gorshkov G.S., Starokozhev S.A., Tikhomirova P.M. The article discusses the development of an affordable ARM 3D printer designed for educational and scientific purposes. It presents a methodology for assembling and programming the device using inexpensive components, such as a Raspberry Pi microcomputer and Nema stepper motors. Hardware and software solutions are described, including the use of a high-speed print head with a color printing function, mixing and changing the nozzle diameter without stopping the printing process, as well as software for converting STL fi les to G-code. The developed ARM 3D printer has the ability to print multi-color models, improving the detail and functionality of the created models and prototypes. Particular attention is paid to the economic availability of the technology, which makes it attractive for educational institutions, students and young scientists working in the fi elds of architectural modeling, prototyping and engineering design. Keywords: automation of modeling, prototyping, high-tech models, additive manufacturing technologies, robotic manipulator, 3D printing, tutorial, ARM 3D printer.
