New bowden extruder · 模型 276783
This is a modified Bowden extruder for my 3D printer. I design and build hobby 3D printer at my free time. -The main innovation-toothed belts instead of using trapezoidal threads on the Z axis-experiences:Stepper motor develops enough torque to bear on the whole axis of the belt and the extruders motors.I suggested therefore Bowden extruder (weight savings of approximately 600 g) and increased the voltage to the motors from 12V to 24V. The engine was still not powerful enough to drive the z axis. The last option is to book a stepper motor with a planetary gear (it is quite expensive). Therefore, now I revamped the Z axis trapezoidal thread. This improved extruder is designed so that it can be printed on the printer. Enlarges the print area of approximately 1.5 cm (hotendys are closer together) and improved cooling using direct blowing. On my printer i tested the other innovative designs. -The main structure is made of aluminum profiles (30x30x500mm). Profiles are linked precisely milled connecting pieces of fiberglass. The resulting stiffness is very good. -The printer is fairly easily transferable (can be split into two sub sections). parts for printing: Print_01.stl Printing method is fdm, material ABS. Print_01.stl Printing method is polyjet, material RGD525. now studying Technical University in Liberec.
