Mobile extrusion machine for the production of composite filaments for 3D printing

This paper represents a new low-cost mobile extrusion system which is ready to manufacture high-quality filament with stable diameter throughout its length. This device allows generating new composite materials for three-dimensional printing. The article contains experiment data proving announced quality and accuracy. Authors represent detailed explanation of principle operation system, diagrams, components of system, etc. 3D printing assumes automated control for the process, so the paper describes the method for temperature control of heater elements and actuators for rolling screw and form-wound coil. For this purpose, the Arduino with the Atmel AVR multifunctional microcontroller was used. In addition, the article provides the structure diagram of the control system and specific features of coding part.
