Abstract
A 3D printer nozzle structure capable of realizing quick printing and no plugging belongs to the field of quick FDM (Fused Deposition Modeling). The 3D printer nozzle comprises a nozzle component module 1, a heating module 2 and a housing module 3. The 3D printer nozzle has the advantages that the structure is novel, simple and compact, the weight is light, the 3D printer nozzle can be replaced as a consumable, the outlet of the nozzle can be heated to reduce the plugging probability and improve the printing efficiency, the magnetic induction heating mode can shorten the preheating waiting time, the waiting time is shortened to 7s from 2 min that is needed by a conventional product available on the market, and as a blower is arranged outside, the 3D printer nozzle is more compact and quicker and is high in flexibility.
Description
Technical field:
This nozzle structure is applied on FDM (Deformation In The Fdm Process) rapidform machine, FDM3D printer port of printer device.
Background technology:
At present, in 3D Deformation In The Fdm Process print procedure, when nozzle is heated to long, the work of stand-by period of operating temperature because of melt cause that the slow plugging fault rate simultaneously of print speed is high slowly, the loaded down with trivial details heaviness of nozzle structure technique blower fan and safeguard and change difficulty, have impact on print quality and operating efficiency, to this, the present invention devises a light and handy 3D printer head structure, can save the heat time, improve the operating efficiency of 3D printer.
Summary of the invention:
The invention provides and a kind ofly can realize printing speed and the 3D printer head of not plug, to solve the of poor quality and inefficient problem of the 3D print job existed at present.Printer head structure is divided into 3 parts from the inside to the outside: nozzle assembly part, heating part, housing parts.
The structure of nozzle assembly part of the present invention is: be followed successively by copper nozzle from the bottom to top, nozzle conduit (including polyfluortetraethylene pipe), nylon jackscrew, it is wherein cone angle in copper nozzle, cone angle is beneficial to hot melt contact area and the extruding of favourable material silk downwards, adjacently with polyfluortetraethylene pipe in copper nozzle fall low frictional resistance, copper nozzle exterior close-fitting flux sleeve, flux sleeve material is 45#, the advantage of this structure: only nozzle is heated, namely be that Rapid hot-melting is carried out to the front-end cross-sectional view printing material silk, it is large that effective containment heat uploads the resistance caused, plug problem, thus realize quick feeding printing.
Heating part of the present invention is: heating adopts the method for magnetic induction heating, be wound around outside flux sleeve with sand hill silver line, the antiseized muff of polytetrafluoro is externally connected with at heater coil, its advantage: shorten the nozzle heat time, contract from about the 2min heat time compared with heating tube or resistance wire and cause 7s and can complete, the antiseized cover of polytetrafluoro can be incubated heating part, and can prevent during printing that melt turns over adhesion affects print quality, advantage: magnetic induction heating means quick heating, quality are good, and structure is simply light and handy.
Housing parts structure of the present invention: be made up of shell and upper cover, present invention process air quantity adopts external fan, by drag chain pipe, wind is guided shower nozzle place, nozzle housing serves as air channel, shell is connected with upper cover screw, nozzle assembly is fixed, a pair feather key is had outside shell, feather key is used for the guide-localization that shower nozzle is installed, outer casing upper cover soldering copper contact piece, be energized after facilitating shower nozzle to install connection, advantage: the weight eliminating four fans compared with Vehicles Collected from Market, allow printing head quick mobile print time inertia less, thus raising print quality, make manufacturing cost lower.
