Background technology
3D printer is also known as three-dimensional printer, is a kind of machine of a kind of accumulation manufacturing technology, i.e. RP technique, it
Be based on mathematical model file, with special wax material, powdery metal or plastics etc. can jointing material, by from level to level
Jointing material come manufacture three-dimensional object.At this stage three-dimensional printer be used to manufacture product, by way of successively printing come
Constructed object, data and raw material are put into 3D printer, and machine can from level to level manufacture product according to program.
Existing 3D printer is commonly equipped with a printing head, a diameter of 0.4mm of usual printing head, due to beating
Print shower nozzle only has one and nozzle diameter immobilizes, when printing a certain structure composition identical region, it is necessary to pass through shower nozzle
Move back and forth progress multiple spot printing, thus cause the low of printing effect, moreover, in print procedure, due to spray
Head is internal to contain impurity, it will usually cause shower nozzle to block, cause shower nozzle can not extruded material printed, now then need to fight each other
Shower nozzle is dredged or changed to print shower nozzle, so be will result in the extension of time-write interval, is further influenceed printing effect.
