Description

A kind of 3D printer
Technical field
The utility model belongs to RP technique field, is specifically related to a kind of 3D printer.
Background technology
3D printer is also known as three-dimensional printer, i.e. a kind of machine of RP technique, it is based on a kind of mathematical model file, use powdery metal or plastics etc. can jointing material, the technology of constructed object is carried out by the mode successively printed, it is a kind of accumulation manufacturing technology, three-dimensional object is manufactured by the jointing material printed from level to level, its general principle is by data and raw material are put in 3D printer, machine can be created product from level to level according to program, and the product printed, and can immediately use.The 3D printer field such as Making mold, industrial design of being everlasting in the past is used to modeling, existing just gradually for the direct manufacture of some products, can be used for jewelry, footwear, industrial design, building, engineering and construction, automobile, Aero-Space, dentistry and medical industries, education, GIS-Geographic Information System, civil engineering, and many other fields.
3D printer and the maximum difference of conventional printer are that " ink " that it uses is out and out raw material.These raw material are fusing after heating, is cooled to solid-state from the printhead shower nozzle of 3D printer after ejection, and to be exactly shower nozzle according to program constantly spray the raw material of liquid and success cools on model for the process of whole printing, and the solid finally obtaining 3D is in kind.But the effect of heat insulation between the fire end of the nozzle structure of existing 3D printer and radiating end is poor, therefore the heat of fire end can be delivered in radiating end fast, so just cause two problems: 1, the heat of fire end is delivered to rapidly in radiating end, cause fire end heat loss comparatively large, energy consumption is higher; 2, the temperature in radiating end is higher, and consumptive material softens too early in radiating end, causes the wire vent inefficiency of shower nozzle, shower nozzle is easily blocked, consumptive material extrudes difficulty.
Shape and/or the size of these 3D printing device shower nozzles are fixing, the consumptive material extruded can only be filiform or the bar of determining shape and size after curing, this also just defines the application scenario of 3D printing device, makes printing device can not adjust shape and the size of the material extruded from discharging opening in real time according to the needs printed.
Existing 3D printer also comprises the workbench that can be elevated, but after 3D printer dispatches from the factory, its workbench cannot regulate, when the shaping work table top of workbench and the plane of motion of nozzle not parallel time, then easily there is tilt problem in the workpiece printed, to have a strong impact on the formed precision printing workpiece, percent defective is higher.In addition, because the lifting travel of workbench is fixed, therefore adjustable height is fixed, distance between workbench and the plane of motion of nozzle excessive or too small time, be difficult to the adjustment by realizing distance to the adjustment of workbench, by controlling the lifting travel of workbench, then can affect the calibration accuracy between nozzle and workbench, defect is obvious.
Utility model content
The purpose of this utility model solves the problem, a kind of novel 3D printer is provided, can convenient adjustment workbench height and gradient, solve that prior art energy consumption is high, the wire vent inefficiency of shower nozzle, shower nozzle are easily blocked, consumptive material extrudes difficulty and print the technical problems such as the shape of cross section of material, size and extruded velocity be non-adjustable.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of 3D printer, comprise frame, be arranged on the nozzle component of upper rack, be positioned at the print platform below nozzle component, print platform is arranged in frame and also can moves up and down, described nozzle component comprises the feed pipe printing material for feeding, be positioned at feed pipe end and can extrude the shower nozzle printing material and the feed unit being sheathed on feed pipe from top to bottom successively, heat-sink unit, insulating unit and heating unit, shower nozzle is provided with the nozzle removably connected, nozzle includes the through hole extruded and print material.
Preferably, the cross sectional shape of described through hole, comprises circle, ellipse, triangle, rectangle or polygon.
Preferably, described heat-sink unit comprises some fin being evenly located at feed pipe outer wall.
Preferably, described fin is circular.
Preferably, described print platform comprises workbench, be positioned at hoistable platform, adjusting nut below workbench, be fixed on the adjusting bolt of workbench lower end and be located at the level meter of workbench side, and adjusting bolt is arranged in one end and the adjusting nut threaded engagement of hoistable platform.
Preferably, also comprise the spring being sheathed on adjusting bolt, the two ends of spring abut with workbench and hoistable platform respectively.
Preferably, the quantity of described adjusting bolt, adjusting nut and spring is four.
Preferably, described level meter is arranged in the groove of workbench side.
The beneficial effects of the utility model are:
1, rotating adjusting nut is passed through, workbench can be regulated relative to the fixed position of hoistable platform, synchronous rotary four adjusting nuts, can regulate up or down by workbench entirety, and then reach the object of spacing of plane of motion of adjustment workbench and shower nozzle; When single adjusting nut is regulated, the depth of parallelism between workbench and the plane of motion of shower nozzle can be regulated, what make between the two is parallel more accurate, whether whole adjustment process is observed to regulate by level meter and is put in place, greatly improve the printing shaping precision of 3D printer, rate of reducing the number of rejects and seconds.
2, the heat that insulating unit effectively can intercept heating unit conducts toward heat-sink unit, thus prevents the thermal loss of consumptive material softening and heating unit too early, has both reduced energy consumption and in turn ensure that consumptive material is easily extruded.
3, by changing the different nozzle in through hole cross section, the shape of cross section of the printing material be extruded, size and extruded velocity is regulated.
