filament injector for 3d printer

prototype 1


4 into 1 system, prototype


failure due to leakage, and stuck of melted filament

prototype 2


4 into 1 system, prototype


heater, sensor, and filament guide


mixed filament from white, black and red filamnet
failure due to leakage, and stuck of melted filament

prototype 3


filamnet injector using steppers


heater, sensor and injector into one block


injection test


injected and mixed filament


two-color mixed


constantly extruded by motor power


controlled by arduino


Movie: play MP4 image00


prototype 4


air-pressure is used to support filament flow


printed in XYZ

prototype 5


fill with filament, mix, push, extrude, and pull

compare with conventional extruder for 3d print


flashforge
