Summary of the invention
In view of this, a kind of 3D printer workbench provided by the invention makes the printing on the same stage of unlike material material become possibility when saving the energy.
For achieving the above object, the technical solution used in the present invention is:
A 3D printer workbench, described workbench bottom or inside are fixed with a plurality of independently heaters, and each heater is the different temperature subregion of corresponding workbench upper surface respectively.By controlling separately each temperature subregion in different temperature ranges, in the time of can accomplishing to use the printed material of unlike material, the unification of different solidification shrinkage rates, is that the printing on the same stage of many materials material becomes possibility on the one hand.Each only heating needs the part of printing on the other hand, saves the energy.
Preferably, temperature subregion appearance and size is identical, is evenly arranged in workbench upper surface.As the selection of being convenient to processing and mechanical field routine, the layout temperature subregion that shape is identical is easy to use.
Optionally, the appearance and size of a plurality of temperature subregions is different.When some special instructions for uses, can select each temperature partitions sizes different.The workpiece of a large amount of processing of needs for example, a kind of material needs one in a big way, and another kind of material only needs a less scope.And for example add in the middle of man-hour at every turn and have a fixing larger part to need heating, temperature subregion is can size larger herein, around less.
Preferably, the profile of temperature subregion is rectangle, square or rhombus.These three kinds of shapes can be seamless be combined in together.
Preferably, the upper surface of workbench is tabular, and workbench inside or lower surface are divided into a plurality of heaters by grid-shaped baffle plate cavity is installed.Preferably workbench interior separation becomes the cavity of a plurality of placement heaters.
Further, the material of dividing plate is insulation material.Reduce heat and run off, further save the energy.
Further, heater comprises heating module, temperature feedback module and master control borad, and the heating that master control borad is determined heating module according to the temperature value of temperature feedback module feedback whether.Each heater is all independent, all can control separately temperature range.Be convenient to the different temperatures of each temperature subregion.
Preferably, heating module is resistance wire, resistor rod or circuit board.Existing other mode of heating also can, electrical heating is comparatively common and practical.
Beneficial effect of the present invention is: the temperature subregion of not processing does not heat, and saves the energy; Each temperature subregion is can temperature different, makes the material that shrinkage factor is different be heated as on the same stage possibility.
Accompanying drawing explanation
