Description
Technical field
The utility model relates to a kind of printer accessory, particularly relates to a kind of novel simple 3D printer extrusion mechanism.
Background technology
Usually in print procedure, the printhead of three-dimensional printer needs to be heated to 190-230 DEG C, in order to not affect the normal work of extruder motor, need a radiator constantly to carry out dispel the heat (horizontal direction) facing to extruder motor direction, need because caloric value is huge fin as auxiliary.On the other hand because three-dimensional printer adopts the mode increasing material and manufacture substantially, in print procedure, do not cooled timely if one deck printing is complete, very easily causing printhead to pull in motion process and cause distortion, therefore needing a radiator to carry out ventilation and heat (vertical direction) from printing the backward printer model of beginning
Prior art FDM extruder has problems: easily block; Be heated uneven; Heat block easily conducts heat to motor, causes motor excessive heating; Between heat block and temperature sensor, transition temperature is insensitive inaccurate; Dispel the heat unhappy; Extruder is existing a lot of too heavy, causes print speed efficiency to reduce; Extruder nearly all adds ventilating fan, causes shower nozzle vibrations in print procedure to cause printer model precision to reduce; Heat block easily causes heat conduction to melt in advance at charging aperture to result in blockage to the material of charging aperture and charging aperture; Current extruder is too complicated, and not easily extraction comes; Directly perceived not, the not blockage problem that causes of easy to clean.
Utility model content
