The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described, obviously, accompanying drawing is described is only a part of the present utility model rather than whole embodiment.
As shown in Figure 1, the self-leveling 3D printer of one that the utility model provides, comprise base 3, on base 3, be fixed with traversing carriage 9, on traversing carriage 9, be connected with shower nozzle 6 and workbench 4, shower nozzle 6 is positioned at the top of workbench 4, on workbench 4, be evenly distributed with multiple calibration points 5, on shower nozzle 6, be fixed with horizontal calibrator 2, horizontal calibrator 2 is in order to measure the vertical range between itself and calibration point 5, and horizontal calibrator 2 is determined the levelness between each calibration point 5 by the relative altitude position of measuring between its fixing initial point and each calibration point 5.Described horizontal calibrator 2 is measurement mechanisms of a distance, its role is to measure the distance between each calibration point on horizontal calibrator itself and workbench.The method of finding range in prior art is more, phase method, impulse method and some mechanical means etc., and in the utility model, except some artificial measuring methods, remaining method for automatic measurement all can use.As preferably, the embodiment that the utility model provides preferably drives the movement of horizontal calibrator by shower nozzle, and horizontal calibrator is determined the difference in height between itself and calibration point by the displacement in short transverse that records self.Thereby comprehensive all differences in height obtain on workbench difference in height between each point, thereby determine the levelness of workbench.Determine by testing us, on the 3D of the individual application printer, the difference in height between each point of workbench is in 1 millimeter, and workbench can be thought level, while adding the error in man-hour, can bear.Further, the altitude information that horizontal calibrator should detect these by connecting line or wireless communication mode flows to the master control set of printer, save as initial data so that for processing result provides reference data, on the other hand for following process provides parameter on the one hand.When application, after horizontal calibrator is received calibration command, understand successively to calibrating with equally distributed nine points of nine grids pattern on platform, and automatically list current each point value.Each point value that horizontal calibrator records, within need remaining on error 1mm, if be greater than 1mm, illustrates that platform assembly precision is nonconforming, need readjust.
Need to illustrate, the 3D printer in the utility model title should be done the understanding of broad sense, and it not only comprises the small-sized 3D printer that individual uses, and also comprises the 3D printer of industrial scale applications, is commonly called as rapidform machine.The standard that above-mentioned workbench difference in height is 1 millimeter can suitably be amplified at technical grade.
As further improvement, as shown in Figure 2, before processing, automatically detect the distance between nozzle and processing platform.After aforementioned levels degree detects and finishes, horizontal calibrator is pulled down on shower nozzle, and to keep the cleaning of nozzle be that follow-up mensuration is prepared.Rear on workbench is fixed with a position sensor, is used for the current height of test nozzles.Workbench is after receiving nozzle height test command; can rise until touch nozzle gradually; connect in order to prevent rigid touching; when workbench approaches nozzle; it is very slow that the rate of climb can become; until nozzle touches the shell fragment on position sensor, record the current accurate height of nozzle.Catch up with and state calibration point test equally, preferably determination data is sent to the master control system of printer herein, master control system is according to the numerical value recording, in conjunction with aforementioned numerical value, can analytical calculation go out workbench height difference everywhere, thereby in print procedure, the spacing of nozzle and platform is made to compensation, guarantee the reasonable distance between shower nozzle and platform.For example the height value of workbench point is slightly high, while carrying out print job at this place, and the numerical value that can exceed according to it, automatic control platform reduces corresponding height; Equally, the height value at workbench point place is lower slightly, and while being printed to this, platform can corresponding rising.As preferably, the rising of workbench should not be vertical with descent path, the 0.2mm of for example A, B point 0.5mm, and do not mean that print job is 0.2mm after A point and A point, decline and compensate 0.3mm suddenly to B point, but rise slowly between A point and B point.Prior art all has higher requirement to the reference platform of processing, the method for the altimetric compensation providing by the utility model, and some have the reference platform of trickle flaw also can meet the demands.Write irregular region at this, eliminate its defect by rising and declining.
According to the numerical value recording, system can analytical calculation go out workbench height difference everywhere, thereby in print procedure, the spacing of nozzle and platform is made to compensation, guarantees the reasonable distance (0.1mm is best) between shower nozzle and platform.For example the height value of workbench point is slightly high, while carrying out print job at this place, and the numerical value that can exceed according to it, automatic control platform reduces corresponding height; Equally, the height value at platform point place is lower slightly, and while being printed to this, platform can corresponding rising.
The self-leveling 3D printer of one that the utility model provides, as further improvement, workbench inside or bottom arrange a heater, keep the temperature of workbench to remain in a certain scope by heating module and thermometric feedback module.Silk material, can Slow cooling in the time of the moulding of workbench surface sediment, reduces cooling contraction, prevents model deformation.Because can causing workbench, heating there is the heat phenomenon that rises, therefore, the impact when reducing deformation on above-mentioned two numerical evaluations, workbench or selection add the material manufacture that thermal deformation is less, or heat laggard line number pH-value determination pH at workbench.
