Abstract
The utility model discloses a kind of nozzle arrangements for 3D printer, comprise: trunnion, the connector be connected with described trunnion one end, the heat block be connected with described connector one end and the shower nozzle be installed on described heat block, the interior bore of described shower nozzle is 1.6mm-1.9mm.Bore in shower nozzle is changed into the size matched with trunnion by the utility model, be specially 1.75mm, the stub bar of molten condition is up moved into by shower nozzle the trunnion that internal diameter is 1.75 ± 0.1mm, even if the frequent pumpback of consumptive material, also this situation can not be blocked, thus solve the problem got stuck, reduce charging fault rate, improve and be printed as power.
Description
Technical field
The utility model relates to 3D printing technique field, particularly relates to a kind of nozzle arrangements for 3D printer.
Background technology
3D printing technique appears at the eighties in 20th century, also referred to as " rapid shaping technique ".Its maximum advantage is without the need to machining or grinding tool, just directly can generate any object from the graph data that Computer Design goes out, thus greatly shorten the R&D cycle of product, boost productivity and reduce production cost.Therefore art circles and industrial quarters is widely used in.3D printing technique, according to the difference of its forming method, stereolithography (stcmolithography can be divided into, SLA), laminated solid mass manufacture (LaminatedObjectManufacturing, LOM), selective laser sintering (SelectiveLaserSintering, SLS), Fused Deposition Modeling (FusedDepositionModeling, FDM) etc.FDM rapid prototyping system and the most essential being different from it and not using laser system of other system, therefore cost is minimum, is also a kind of 3D printing technique of extensive use the most at present.
FDM technique is generally that solid-state low melting point filamentary material is heated to semi-molten state, as PLA or ABS etc.Then, extruded, according to every layer, object institute projected path, successively manufactured, often manufacture a decline thickness or printing head of one deck workbench and to rise a thickness, so repeatedly finally construct whole entity.In whole process, wire vent speed and the uniform and stable degree going out filament diameter are the most important factor determining 3D printer machining accuracy and surface quality.For addressing this problem, researchers ensure all even stable of extruder head wire vent by improvement pay-off and heating head.But, the nozzle structure of Fused Deposition Modeling (FDM) 3D printer apparatus adopts trunnion (Teflon material) directly to import to shower nozzle inside on the market at present, unfixing, and the internal diameter of trunnion is that in 1.75 ± 0.1mm nozzle, bore is 2.3 ± 0.1mm, print procedure consumptive material has the necessary operation of frequent pumpback up and down, the silk material of lower end molten condition (line diameter ratio original thick) up frequent pumpback, because melting silk expect up pumpback process from high temperature nozzle more and more away from, rapid cooling thus cause silk material to be stuck in trunnion (Teflon material) place, charging is caused to have some setbacks, and then cause plug.
Therefore, prior art existing defects, needs to improve.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of nozzle arrangements for 3D printer.
The technical solution of the utility model is as follows: the utility model provides a kind of nozzle arrangements for 3D printer, comprise: trunnion, the connector be connected with described trunnion one end, the heat block be connected with described connector one end and the shower nozzle be installed on described heat block, the interior bore of described shower nozzle is 1.6mm-1.9mm.
The interior bore of described shower nozzle is 1.75mm.
Described connector is PEEK connector.
The heated aluminum block of described heat block to be material be aluminium.
Adopt such scheme, nozzle arrangements for 3D printer of the present utility model, bore in shower nozzle is changed into the size matched with trunnion, be specially 1.75mm, the stub bar of molten condition is up moved into by shower nozzle the trunnion that internal diameter is 1.75 ± 0.1mm, even if the frequent pumpback of consumptive material, also this situation can not be blocked, thus solve the problem got stuck, reduce charging fault rate, improve and be printed as power.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for the nozzle arrangements of 3D printer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Refer to Fig. 1, the utility model provides a kind of nozzle arrangements for 3D printer, comprise: trunnion 2, the connector 4 be connected with described trunnion 2 one end, the heat block 6 be connected with described connector 4 one end and the shower nozzle 8 be installed on described heat block 6, the interior bore of described shower nozzle 8 is 1.6mm-1.9mm.In the present embodiment, the interior bore of described shower nozzle 8 is preferably 1.75mm.
Further, described connector 4 is PEEK connector.Described heat block 4 for material be the heated aluminum block of aluminium.
In print procedure, silk material extrudes shower nozzle 8 after nozzle interior fusing, the shower nozzle 8 that the stub bar of molten condition is 1.75mm by interior bore is up moved into the trunnion 2 that internal diameter is 1.75 ± 0.1mm, because both internal diameters are identical, even if the frequent pumpback of consumptive material, also can not block this situation, thus solve the problem got stuck, reduce charging fault rate, improve and be printed as power.
In sum, the utility model provides a kind of nozzle arrangements for 3D printer, bore in shower nozzle is changed into the size matched with trunnion, be specially 1.75mm, the stub bar of molten condition is up moved into by shower nozzle the trunnion that internal diameter is 1.75 ± 0.1mm, even if the frequent pumpback of consumptive material, also this situation can not be blocked, thus solve the problem got stuck, reduce charging fault rate, improve and be printed as power.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
