Abstract

The invention relates to a 3D printing method based on a PolyJet technology. As layers with the same information are combined, when data is decomposed, the final data volume is smaller, and the data transportation is convenient; a main control board controls a velocity V of a nozzle moving along a guide rail according to a layer parameter L, so that the height after spraying reaches an anticipant height; and once movement is only needed to spray multiple layers of materials with the same data onto a worktable to finish multilayer printing, so that the moving distance of the nozzle is greatly shortened, the equipment wear is reduced, and the equipment life is prolonged.

MPU printing document information to be decomposed into a multi-layer, n-layer and form a set of the information to be printed; B • Initialize the current layer number X = l;. C initializing layer parameter L = 1; D. Comparison layer X and X + 1 information set first layer, the same set of information, leaving only layer information X, X + 1 layer information delete, change layer corresponding to layer parameter X L = L + 1, X = the number of layers while changing the current X + 1, is determined whether X is greater than n, the process proceeds to step greater than E, otherwise, returns to step D; different sets of information X and X + 1 layer information layer information is retained, and stores the number of layers L, the current change X = X + 1, Analyzing X is greater than n, the process proceeds to step greater than E, otherwise, returns to step C; E. resets the current number of layers X = l; F • X MPU reads the layer information and a corresponding set of layer parameters L, the master L layer parameters based on the control plate head along the guide rail speed V, and the injection stage photopolymer according to the set of information, when the number of layers L = 1, the speed V = 15m / s, when the number of layers L = 2 , the speed V = 7.5m / s, so that a sufficient jet ejected from the head, the UV light is irradiated with ultraviolet light emitted by the lamp is located photopolymer, the photopolymer so that the cured, X = X + L, is determined X是否大于n,大于则结束打印,否则返回步骤F。 If X is greater than n, is greater than the end of the print, otherwise step F.

[0011]由于将相同信息的层数组合到一起,因此在数据分解时,最终的数据量较小,方便数据的传输,并且主控板依据层数参数L控制喷头沿着导轨运动的速度V,从而使得喷射后的高度达到预期的高度,只需要一次移动,即可将数据相同的多层材料均喷射到工作台上, 完成多层打印,大大减少了喷头运动的距离,从而减少了设备的磨损,延长了设备的寿命。 [0011] Since the number of layers of the same composition information together, so when data is decomposed, the final amount of data smaller, easier to transport data, and control board based on the number of layers along the head velocity control parameter L of the guide rail V , so that the height of the jet reaches the desired height, moved only once, to the same data multiple layers of material are injected into the table, completed multilayer printed, greatly reducing the distance of movement of the head, thereby reducing the apparatus the wear and extend the life of the equipment.
