75mm, nozzle is squeezed going out is normally 0.
4mm diameter (to go after precision, still have smaller diameter) . A few people keep clear of now with needle disclose nozzle residual. But this is not a very good idea. Above all, may bring about aperture to be out of shape or greaten, it is more difficult to make print (section program does not know to want extruding how many material) . Next, before long hind it still can appear to jam again nozzle. Cold help a technology actually very maneuverable. Insert a paragraph of wire, heat extruder lets wire be squeezed from nozzle piece a few (if stemmed really,the likelihood cannot be squeezed piece) , or heat working temperature. Shut 3D Printing engine next. When should heating up end to be in working temperature normally, can pull wire rod freely. After complete refrigeration, wire will be caky live, cannot pull out come. Hang awaits temperature namely slightly under caky level, pull wire rod quickly, should be solid state for the most part right now. When wire is caky, can capture fragmentary in hot end those who distributing is residual. Discover it was polluted by black material possibly still, can have a few even apparent drossy. There still can be more inside the wire of solid state. Cut off this paragraph of share that gets pollution, repeat this process. Heat and the time that the cooling likelihood that heat up end wants to cost a few minutes, but this should be gotten easily than other method much. Repeat a few times more according to the circumstance, the wire rod that pulls finally will be very clean, this explains the extreme of wire is clean. CNC Milling CNC Machining
