The course of processing of 3D printer or rapidform machine is exactly accumulation and the cooling procedure of melted material, in cooling procedure, rapidoprint can produce certain solidification shrinkage, the material solidification shrinkage factor of unlike material is different, what thus cause is when the file printing of multiple unlike material, owing to the solidification shrinkage rate between adjacent materials is different, result in the material of unlike material can not print simultaneously, or when printing, percent defective is too high simultaneously.
It addition, the difference of material temperature and ambient temperature can affect the shrinkage rates of material in cooling procedure, in order to reach the contractive effect of optimum, the technological means that prior art adopts is heating work platform. But adding man-hour, the processing object of the overwhelming majority all only uses the part having arrived work platforms rather than whole, and the power of heating module is relatively big, and thus monoblock type heating work platform also result in bigger energy waste.
Summary of the invention
In view of this, a kind of 3D printer work platforms provided by the invention, make the printing on the same stage of unlike material material be possibly realized while saving the energy.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of 3D printer work platforms, bottom described work platforms or inside is fixed with multiple independent heater, each heater temperature subregion that corresponding work platforms upper surface is different respectively. Being in different temperature ranges by the individually each temperature subregion of control on the one hand, it is possible to when accomplishing the printed material using unlike material, the unification of different solidification shrinkage rates, is that the printing on the same stage of many materials material is possibly realized. The part that only heating needs print every time on the other hand, saves the energy.
Preferably, temperature subregion overall dimensions is identical, is evenly arranged in work platforms upper surface. As being easy to processing and the selection of mechanical field routine, the layout temperature subregion that shape is identical is easy to use.
Optionally, the overall dimensions of multiple temperature subregions is different. When some special instructions for uses, it is possible to select each temperature partitions sizes different.Such as one workpiece needing a large amount of processing, a kind of material needs one in a big way, and another kind of material has only to a less scope. And for example adding every time and have in the middle of man-hour a fixing bigger part to need heating, temperature subregion can be larger in size herein, around less.
Preferably, the profile of temperature subregion is rectangle, square or rhombus. These three shape can be seamless be combined in together.
Preferably, the upper surface of work platforms is tabular, and work platforms inside or lower surface are divided into multiple heater to install cavity by grid-shaped baffle plate. The cavity of multiple placement heater it is separated into inside preferred work platforms.
Further, the material of dividing plate is insulation material. Reduce heat losses, save the energy further.
Further, heater includes heating module, Temperature Feedback module and master control borad, according to the temperature value of Temperature Feedback module feedback, master control borad determines that the heating of heating module is whether. Each heater is all independent, all can individually control temperature range. It is easy to the different temperatures of each temperature subregion.
Preferably, heating module is resistance wire, resistor rod or circuit board. Other mode of heating existing also can, electrical heating is relatively conventional and practical.
The invention have the benefit that the temperature subregion do not processed does not heat, save the energy; Each temperature subregion can temperature different, make the material that shrinkage factor is different be heated as possibility on the same stage.
