High-speed FDM 3D printer

Additional Information: These are the main advantages of my 3D printer. The use of a steel frame, rails and high-speed motors make it possible to achieve a printing speed of 300 mm /s. The design with two independent printing heads allows quickly pass from one material to another. An extruder which heats up to 450 ° C makes it possible to print using high-temperature plastics (such as PEEK). A closed steel case increases the stability of the printing process. A 32-bit controller with original software provides complete autonomy of the printer. Besides, the quality of printed objects is very high (without nodules and burrs).
