All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present in the cutting process of 3D printing, because the distance of tool bit and paper surface is not big, can destroy required part occasionally when reciprocating sliding, reduce the model precision, can lead to whole model to damage even to be unfavorable for dismantling of model shaping back waste material. Based on the technical scheme, the type of the cutting tool bit is changed, the rotary knife is adopted by the cutting platform to cut the medium layer, the gap after cutting is increased, the waste material after the model is formed can be conveniently removed, the problem that the required part is occasionally damaged when the tool bit slides back and forth, the model precision is reduced, and even the whole model is damaged can be effectively solved.
For the convenience of understanding the embodiment, a detailed description will be given to a 3D printing cutting method disclosed in the embodiment of the present invention.
The first embodiment is as follows:
referring to fig. 1, a schematic flow chart of a 3D printing cutting method according to an embodiment of the present invention is shown. The 3D printing cutting method can be applied to, but is not limited to, a cutting platform of a 3D printing apparatus, and can be implemented by a control device of the cutting platform, for example. As shown in fig. 1, the 3D printing and cutting method specifically includes the following steps:
step S101, obtaining layered single-layer model information of a model to be printed, wherein the single-layer model information comprises outline information of an outline of a graph to be cut.
The model to be printed is obtained from the corresponding model processing device, for example from a computer loaded with model processing software. The computer is provided with slicing software corresponding to the 3D printing device, and after modeling is completed, slicing processing is carried out on the obtained model to obtain layered single-layer model information.
In a concrete implementation, a desired digital model is created using software such as 3D MAX or CAD, and the created digital model is introduced into slicing software corresponding to the printing apparatus, thereby performing a hierarchical processing on the digital model. The layered single-layer model information is transmitted to a processor of the printing device by the computer. In a possible embodiment, the printing device stores single layer model information for each layer, facilitating continued printing after the computer is shut down.
And S102, controlling a rotary knife of the cutting platform to cut the corresponding medium layer based on the profile information to obtain the medium layer to be removed.
Wherein the medium layer is in a sheet form, and paper can be selected but is not limited.
In a possible embodiment, the rotary knife of the cutting platform can be a small rotary knife and driven by a rack synchronous belt to perform cutting operation, namely cutting the figure outline on the medium layer.
During concrete implementation, after receiving the individual layer model information of printing device treater output, under the transmission of gear hold-in range, the rotatory sword of control carries out accurate cutting according to profile information, and the cutting mode of rotatory sword can improve ordinary tool bit cutting thoroughly to the gap that leaves is very favorable to demolising of later stage waste material, also because it does not need the heating, and the power consumption is low, and is pollution-free, is superior to the laser tool bit.
And step S103, controlling the rotary knife to cut a removal auxiliary line on the medium layer to be removed so as to remove the waste material of the medium layer to be removed.
In order to facilitate later-stage removal, removing auxiliary lines are cut on the medium layer to be removed, on which the graphic outlines are cut.
In the embodiment of the invention, the cutting platform adopts the rotary cutter to cut the medium layer, so that a gap after cutting is increased, the removal of waste materials after the model is formed is facilitated, and the problems that the required part is occasionally damaged when the cutter head slides back and forth, the model precision is reduced, and even the whole model is damaged are effectively solved.
Considering that the cutting of the auxiliary line is necessary after the cutting of the figure outline of each medium layer is finished, otherwise, the model cannot be taken out after the printing is finished. In order to facilitate later-stage removal, the traditional method is to cut horizontal and vertical straight lines outside the outline of a required graph, parallel to the edges of paper, according to the size of the graph, and divide redundant parts into blocks to facilitate later-stage removal. However, each layer of cutting process needs to be carried out more than ten times on the whole breadth, and the printing time is greatly increased. Based on the above, the removal auxiliary line cut on the medium layer to be removed is a divergent line extending from the outer edge of the pattern profile of the medium layer to be removed to the edge of the medium layer.
Wherein the number of divergent lines is determined according to the complexity of the model to be printed. For example, referring to fig. 2, when the complexity of the model to be printed is low, that is, the model is high in integrity and free of fine details, and the graphic profile of each layer is not much different, four basic dismantling auxiliary lines are selected; when the complexity of the model to be printed is medium, namely the outline of each layer is greatly different, and the model has local details, an eight-divergence type line cutting method is selected, namely four additional dismantling auxiliary lines are added on the basis of the four basic dismantling auxiliary lines; when the complexity of the model to be printed is high and complex structures such as hollow structures and porous structures are more, the auxiliary lines for local dismantling are added for the complex structure parts. It should be noted that the total number of the removal auxiliary lines does not exceed a preset value, for example, 16.
The complexity of the model to be printed is determined according to the number of cutting lines and the number of grids of the model to be printed.
The level of complexity of the model to be printed is assumed to be divided into three levels, namely low level, medium level and high level. Referring to fig. 3, after the computer builds the models to be printed, the models to be printed are all composed of triangular or quadrilateral meshes, and the more meshes represent the higher complexity. After the model to be printed is built, the number of cutting lines of the model to be printed is automatically detected, the cutting lines may be specified by relevant personnel, a top view of the model after cutting is shown in fig. 4 (fig. 4 only uses 8 cutting lines as an example, and is not limited), and it should be noted that fig. 4 is only an example. And if the number of the cutting lines of the model to be printed is less than a preset low threshold value, determining that the complexity of the model to be printed is low. The preset low threshold may be defined by itself each time modeling is performed, or a default value of the system may be selected, and the preset low threshold may be 8, 9, 10, or the like.
When the number of cutting lines of the model to be printed is greater than or equal to the preset low threshold, the grid number of each partition (see 8 partitions in fig. 4) formed by adjacent cutting lines is automatically detected (for example, the grid number can be directly read by 3Ds Max software), and the grid number is determined. The larger the grid number is, the higher the complexity of the segmentation part is, and when the grid number is less than or equal to a preset threshold value, the complexity of the model to be printed is determined to be middle; and when the number of the networks is larger than a preset threshold value, determining that the complexity of the model to be printed is high, and adding a removing auxiliary line in the part, namely partially removing the auxiliary line. I.e. when the cutting line exceeds a preset low threshold, the density of the removal aid lines is related to the number of nets.
It should be noted that the complexity of the model to be printed may be determined by a computer analysis connected to the printing apparatus. After the computer determines the number of the dismantling auxiliary lines, namely the divergent lines, of the model to be printed, the dismantling auxiliary lines are sent to a cutting platform of the 3D printing device through a processor of the 3D printing device. Based on this, the step S103 includes: acquiring the number of the divergent lines; and controlling the rotary knife of the cutting platform to cut the number of the removing auxiliary lines on the medium layer to be removed.
When cutting each layer of medium layer to be removed, divergent lines are cut from the outer edge of the figure outline to the edge of the cutting range, the number of the lines depends on the complexity of the model to be printed, meanwhile, the cutting mode of the rotary knife increases the gap after cutting, and the removal of waste materials after model forming is facilitated.
In consideration of technical defects of discontinuous printing and modeling, manual medium delivery and the like in the prior art, in a possible embodiment, in order to realize integration of printing and modeling, save forming time and avoid quality accidents caused by errors in the direction of manually delivered media and the like, an outlet of a printing platform of a 3D printing device is connected to a cutting platform through a transmission device such as a conveyor belt, and after printing is finished, a medium layer is directly transmitted to the cutting platform through the transmission device without manual delivery.
Because the cutting speed of each layer is slower than the printing speed, the next medium layer can be printed when each layer starts to be cut, and the next medium layer is immediately conveyed to the cutting platform after the cutting of the layer is finished, so that the cutting can be carried out uninterruptedly, and the front-end printing time is saved. Based on this, in another embodiment, before step S102, the method further includes: and sending a next layer printing instruction to a printing platform of the 3D printing device so that the printing platform prints a next layer of medium layer. Correspondingly, after step S102, the method further includes: and sending a transmission instruction to a transmission device of the 3D printing device so that the transmission device transmits the next medium layer to the cutting area of the cutting platform.
In one embodiment, before step S102, the method further includes: scanning the graphic code on the corresponding medium layer; analyzing the graphic code to obtain the layered identification of the corresponding dielectric layer; and judging whether the sequence of the currently printed medium layers is disordered or not according to the layering identification. If the confusion exists, the alarm is controlled to give an alarm.
When concrete realization, can be when every layer dielectric layer prints, print the graphic code that contains this page of information of several layers such as bar code or two-dimensional code in upper left corner or other specified area, cut the platform and install graphic code recognition device additional, discern this graphic code and obtain this layering sign, compare this layering sign with the layering sign of the dielectric layer that cuts last time, whether the order of the dielectric layer of confirming current printing is chaotic, can report to the police when appearing the confusion and indicate, thereby avoid the wrong seal problem of the chaotic number of layers.
In order to more precisely control the accuracy of the cropped image outline, the method further comprises: and acquiring the cutting track of the rotary knife acquired by the induction sensor. Specifically, the cutting platform is further connected with an induction sensor, and the induction sensor can be but is not limited to an infrared sensor; this inductive pick up can respond to the cutting orbit of rotatory sword to with this cutting orbit send to cut the platform.
The step S102 includes: and adjusting the moving direction of a rotary knife of the cutting platform according to the profile information and the cutting track so as to cut the corresponding medium layer to obtain the medium layer to be removed. The contour information is compared with the cutting track, and if the offset distance is determined to be greater than the preset distance, the moving direction of the rotary knife of the cutting platform is adjusted to reduce the offset distance and improve the cutting accuracy.
After cutting, white latex is respectively coated on the figure outline part and the waste material area part in the figure 2 by using a roller or hot melt adhesive paper is directly used, the next medium layer to be cut is dragged to the upper part of the layer, the cutting platform is lifted, and the medium layer is pressed on the heating plate on the upper part to bond the layers. And repeating the cutting process and the bonding process until the printing of each layer is finished.
And after printing is finished, taking out the bonded medium layer from the cutting platform. Firstly, removing the part outside the cutting area (see figure 2), taking out the part of the cutting area, removing the waste outside the part with lower complexity of the model structure, and finally carefully removing the parts with more complex structures such as hollow parts, holes and the like with high complexity of the model by using tools such as tweezers, a knife and the like.
In the embodiment of the invention, the advantages of low energy consumption and environmental protection of the rotary cutter cutting are applied to 3D printing, the problem that a common cutter head cannot cut completely is solved while a model is printed accurately, the traditional block cutting mode is replaced by the divergent lines, the number of the lines is intelligently selected, the difficulty of waste material removal is greatly reduced, and the model printing time is shortened.
