Abstract

The invention discloses a 3D waxwork printer. A wax block is placed inside a temperature-control iron resistance heating container; after the wax block is heated to be melted, the melted wax is conveyed through a metallic conduit into a metallic print head which is a reciprocating-type plunger pump; and fan water-cooled copper blocks fit on the periphery to cool the print head. A temperature sensor is contained in the copper block. If temperature is too high, the fan will be triggered to speed up so as to expedite heat dissipation. In the printing process, the print head is controlled by a computer; driven by a gear, the print head moves according to three-dimensional model data saved in the computer to draw two-dimensional layers layer by layer so as to finally pile up a three-dimensional waxwork. By accurately controlling temperature of input liquid wax and the print head to output semi-solid wax, wax in the form given by the computer reaches the highest degree of adhesion so as to finally print a smooth and complete three-dimensional waxwork body.

Background technology

Along with the fast development of printing technique, the 3D printing technique of printable 3 D stereo material object obtains increasing application, and this technology of order has been used to the printing etc. of personalized articles for use, Making mold, industrial design, biologic-organ.

3D printing heat is melted the accumulation method of forming and is adopted Low Temperature Thermal to melt printing head, by heater by material heating and melting in shower nozzle, the path that shower nozzle controls by Computer Design CAD individual-layer data under gear drive is extruded and is deposited on the position of specifying, thermoplastic cooling curing and with the material binding of surrounding, pile up layer by layer, final formation 3d entity.

Current heat is melted the accumulation method of forming and is generally used the filamentary materials such as ABS plastic, PLA, nylon, rely on gear to push to heating shower nozzle forward to realize melting, and gear just cannot be adopted to push raw material forward for block wax, add and control poor to temperature, too low temperature makes the degree of adhesion between wax layer low, too high temperature makes waxen imagen be out of shape, and the smooth high-quality 3D that cannot realize wax prints.

Summary of the invention

Object of the present invention is exactly cannot input block wax print to solve 3D printer, and printing head temperature controls the not good defect causing wax stone Forming Quality difference, provides a kind of 3D waxen imagen printer.

The technical solution used in the present invention is as follows.

Be high-temperature resistance plastice case for melting the container outermost layer of block wax, the outside of case studs with a numeric display, a temperature setting device and a power switch, and numeric display is wherein used for the temperature upper limit of displays temperature setting apparatus setting; Temperature setting device wherein has two buttons, and one is on temperature setting device button, often presses once, and the numerical value of numeric display increases by one, and another is under temperature setting device button, often presses once, and the numerical value of numeric display reduces one; Power switch is wherein for controlling the power supply supply of numeric display, temperature setting device and heating resistor.

The interior survey wall of high-temperature resistance plastice case and bottom stud with for heat insulation ceramic block, a heating resistor is also equipped with for heating in the bottom of high-temperature resistance plastice case, in addition, temperature sensor is also equipped with in the bottom of high-temperature resistance plastice case, for measuring the Current Temperatures information in high-temperature resistance plastice case.

Iron pan for placing wax stone is positioned within high-temperature resistance plastice case, fixed effect is reached by thermal insulation ceramics, there is an aperture middle, bottom of pot, and aperture is connected to high-temperature resistance plastice flexible pipe, and flexible pipe is communicated to the water-cooled printing head with temperature control through the aperture of case always.

Water-cooled printing head with temperature control is reciprocating plunger pump, to fit outside plunger displacement pump copper tank, the in-built full water of tank is used for heat radiation, to fit outside tank radiator fan, tank wherein side is also fitted a temperature setting device and a numeric display, temperature setting device wherein has two buttons for the set temperature upper limit, the temperature upper limit of numeric display displays temperature setting apparatus setting wherein, powers by printer electric power system is unified with the device on the water-cooled printing head of temperature control.

Water-cooled printing head with temperature control is fixed on on business-like XYZ three-axis moving parametric controller, and its movement locus is specified by the three-dimensional data that computer design is good.

Detailed description of the invention

Below in conjunction with embodiment, the present invention is further illustrated, but not as limiting to the invention.

As shown in Figure 1, block wax is put into the container 1 melting block wax, open the power switch 8 be embedded on high-temperature resistance plastice 2, (fusing point of wax is 57 ~ 63 DEG C the temperature upper limit of the heating-up temperature setting apparatus 5 be embedded on high-temperature resistance plastice case 2 to be set as 90 DEG C, be set to 90 DEG C and can guarantee that wax melts completely), at normal temperatures, heating resistor 9 can heat always, until just can heating be suspended when the temperature sensor 12 in case detects that temperature arrives 90 DEG C, after suspending heating, when temperature drops to lower than 90 DEG C, heating resistor 9 restarts work.

Under the continuous heating of resistance heater 9, wax melts gradually, and after wax merges completely, open the power switch 24 of business-like XYZ three-axis moving parametric controller 15, by high-temperature resistance plastice flexible pipe 14, wax will flow to the water-cooled printing head 20 with temperature control.

Temperature upper limit with the temperature setting device 17 on the water-cooled printing head 20 of temperature control is set as that 50 DEG C (according to the difference of wax, corresponding temperature can be set, be not difficult to because temperature is too high to make wax solidify distortion, or because temperature is too low, cause the wax premature solidification sprayed to make between wax material, to be difficult to laminating).

When being fitted in the temperature sensor 23 on the copper tank in side 22 and sensing that temperature with the copper tank 22 on the water-cooled printing head 20 of temperature control is higher than 50 DEG C, radiator fan 24 automatically startup dispels the heat, and rotating speed is directly proportional to current copper tank 22 temperature.

Water-cooled printing head 20 with temperature control is fixed on current main flow business-like XYZ three-axis moving parametric controller 15, and its movement locus is specified by the three-dimensional data that computer design is good.

Under the effect of reciprocating plunger pump 21, wax sprays from the water-cooled printing head 20 with temperature control and moves along XYZ axle, and wax material is piled into 3 D stereo material object gradually.
