Description
Technical field
This utility model belongs to 3D printing device technical field, particularly relates to a kind of based on the double shower nozzle dislocation type extruder of the water-cooling type on FDM 3D printing device.
Background technology
Existing pair of shower nozzle extruder is the important component part on 3D printing device, and the double shower nozzle extruders on current existing 3D printer there is problems in that
1. nozzle location is fixed: two nozzles of double shower nozzle extruders of existing structure are all the time in a plane, and in double end extruder print procedure, only one of which nozzle is in work all the time, and what idle nozzle may streak current printable layer again completes part, damages.Surface to make extruder head printing shaping good is not destroyed by another extruder head, needs the nozzle making two extruder heads to be strictly in same level, and this is the highest to requirement of assembling；On the other hand, even if the nozzle of two extruder heads is installed and is in same level, the molding mode of FDM 3D printer is that extruder head extrudes plastic shaping, and the nozzle being therefore at off position is likely to damage printed surface through the circuit that another nozzle print is good.
2. Applicable temperature scope is little: some large-scale 3D printers often utilize greenhouse to reduce large-scale printout internal stress, extruder, printer model are all in greenhouse, thus avoid the generation of the defects such as Bulk plastic printout alice, cracking, greenhouse temperature is up to 70-80 degree, but extruder upper wire feeding hose channel part (trunnion) temperature need to keep less than 50 DEG C, result in blockage in order to avoid printing silk softening；Owing to ambient temperature is too high, trunnion temperature cannot be down to less than 50 DEG C by conventional fan coolling method.
3. rate of cooling is slow: the material that FDM 3D printer is conventional has PLA, ABS, PETG etc., and wherein the softening temperature of PLA is about 60 DEG C, is minimum in conventional printed material.Cooling at trunnion is concerned important by chiller, if because printed material softens the most melted at trunnion, it will cause plug fault, so the temperature at trunnion to control below 50 DEG C；When ambient temperature is higher or print speed is slower, air cooling effect is deteriorated, and plug phenomenon easily occurs, causes and print unsuccessfully, make a big impact the stability of FDM 3D printer.
Summary of the invention
