[0041] 实施例一 [0041] Embodiment 1

[0042] 如图1所示，本发明提供一种3D打印机的单喷头彩色进料方法，包括步骤SI〜步骤S3: [0042] 1, the present invention provides a single nozzle color 3D printer feed method, comprising the steps SI~ Step S3:

[0043] 步骤SI，根据3D模型确定各种颜色的条形颜料段的需求量和所有条形颜料段的打印顺序；具体的，首先需要中确定3D模型的各种颜色的条形颜料段的需求量和所有条形颜料段的打印顺序，然后即可根据各种颜色的条形颜料段的需求量确定出每一条形颜料段的长度； [0043] step SI, based on 3D models and demand determine the order of all segments of the various color stripe paint pigment segment of the bar; in particular, you first need to determine the stripe in various colors of paint section of 3D models demand and print order of all segments of the bar color, then we can determine the length of each segment of the bar pigment according to the demand of various colors strip paint segment;

[0044] 步骤S2，根据各种颜色的条形颜料段的需求量切割对应长度的条型颜料段，并根据所有条形颜料段的打印顺序将切割好的各条型颜料段依序输送入与3D打印机的喷头连接的彩料管道中；具体的，如图2和3所示，可据各种颜色的条形颜料段的需求量从不同的颜色料盘中切割相应长度的条形颜料段，然后根据所有条形颜料段的打印顺序由各色的颜料管道9将各条形颜料段平放入一个与3D打印机的喷头2连接的彩料管道3中，所述彩料管道3的直径可与各条形颜料段的直径相同管子，以保证给料的精确度，所述彩料管道3可以是直线管道也可以是如图2和3所示的环形管道，另外，条形颜料段的切割可以是人工切害I]，也可以是计算机自动切割，或计算机控制机械装置进行切割，切割的时间可以是打印时边打印边切割，也可以是打印前切割，在此都不作限制； [0044] step S2, the various colors according to the demand of the cutting bar segment corresponding to strip paint pigment segment length, and the diced pieces of pigment segment sequentially delivered into the pigment according to the print order for all segments of the bar color feed line and nozzle 3D printer connected; specifically, FIG. 2 and 3, according to the demand of various colors can strip paint pigment segment corresponding length of the strip cut from a different color trays 3 section, and then by the colored pigment pipe 9 each strip paint color flat in the feed line segment a 3D printer nozzle 2 connected pigment according to the print order of all segments of the bar 3, the diameter of the color material conduit 3 may be with the same diameter of each pipe section bar pigment, in order to ensure the accuracy of material to the color material may be a straight pipe conduit 3 to be 2 and the annular duct is shown in FIG. 3, addition, strip segment pigments Cutting can be manual cut harm I], can also be computer automated cutting, or computer-controlled mechanical device for cutting, cutting time can be cut when the print side of the print side, it can be cut before printing, in which no restrictions;

[0045] 步骤S3，将所述彩料管道中的各条型颜料段推送至3D打印机的喷头进行3D打印。 [0045] to step S3, the color pigment feed pipe to the nozzle segments each Tweet 3D printer for 3D printing. 具体的，各条形颜料段在彩料管道中依序排列完毕后，可在彩料管道内的最后一段条形颜料段的后端输送一推进块，如一根未切割的完整条形颜料，从而对彩料管道内的各条形颜料段施加往前的推力，实现将各条型颜料段依序推送至3D打印机的喷头。 Specifically, after each of the color stripe color segments arranged sequentially feed pipe is completed, the rear end of the last paragraph of the strip can be a pigment color material segments within a conduit to promote transport block, such as a complete bar uncut pigment, thereby exerting a forward thrust of each strip paint color material within the pipe section to achieve each bar segment sequentially pushed to paint nozzle 3D printer. 这里把步骤SI中确定出的抽象的各种颜色的条形颜料段的需求量和所有条形颜料段的打印顺序通过步骤S2中的切割与排序，变为一种真实的、外在的，多条形颜料段的排序与摆放，不需要多喷头，仅需一个喷头就可以打印出彩色的3D模型。 Here the print order demand determined in step SI in various colors abstract stripes paint pigment segment and all segments of the bar by step S2 cutting and sorting, into a real, external, Sorting and put more pigment segment of the bar, no more guns, only one nozzle can print out a color 3D models.

[0046] 优选的，步骤S3中，在3D打印机的喷头每打印一个新的条型颜料段之前，将该新的条型颜料段前部的混合颜料去除。 Before [0046] Preferably, in step S3, the nozzle 3D printer prints a new strip for each type pigment segment, the new segment type pigment mixed pigments of the front portion is removed. 相应的，步骤SI中，各种颜色的条形颜料段的需求量包括该条形颜料段的实际打印量和该条形颜料段与前一种(前部)条形颜料段的混合颜料的去除量。 Accordingly, the step SI, the demand for strip paint segment various colors including the actual amount of the strip pigment print segment and the segment of the strip pigment mixed with pigments former (front) strip paint segment removal. 具体的，由于不同颜色的条型颜料段刚开始融化时会颜色相混，所以当打印头需要换颜色时，需要将新的条型颜料段前部的混合颜料去除。 Specifically, due to the different colors of pigment Rigid bar will begin to melt when mixed color, so when the print head needs to change color, you need to type a new hybrid pigments of paint to remove the front section. 所以当打印头需要换颜色时，例如可把喷头移动到旁边一个由计算机控制的夹子处，可以在喷头喷出一定长度的混合色料以后，通过夹子把混合色料夹断，然后控制喷头移回刚才停止打印的位置，用新的条型颜料段继续打印。 So when the print head needs to change color, for example, the nozzle is moved to the next one clip at a computer-controlled, you can spray nozzle after a certain length of mixing pigment, mixing the pigment clip by clip-off, and then control the nozzle shift Back just to stop printing position, with a new bar pigment segment continue printing. 所以，相应的各种颜色的条形颜料段的需求量不仅要考虑该条形颜料段的实际打印量，还需要加上该条形颜料段与前一种颜料段的混合颜料的去除量。 Therefore, the demand for strip paint colors corresponding segment not only to consider the amount of the actual printed color bar section, but also need to add the removal of the strip paint pigments mixed with the front section of a pigment segment.
