Fig. 1 is a schematic flow chart of a file processing method applied to 3D printing according to an embodiment of the present invention, where the file processing method applied to 3D printing according to the embodiment of the present invention is applicable to a case of reducing a print file storage space in 3D printing, and specifically, the file processing method applied to 3D printing according to the embodiment of the present invention includes:
and step 100, acquiring the input printing model file.
In this embodiment, the principle of the 3D printing technology is: firstly, a 3D digital model is created on a computer, then "printing materials" such as powder or colloid are loaded into a printer, the printer is connected with the computer, 3D digital model data in the computer are read, the movement and material output of a printing nozzle are controlled, the "printing materials" are laminated and added into a layer, and finally, a blueprint on the computer is changed into a real object. In the 3D printing process, after the 3D printing software generates the preset printing model, the printing model file can be stored, common 3D printing methods comprise LCD photocuring printing and DLP photocuring printing, the generated printing model file is generally the 3D model file obtained in the photocuring printing, and the 3D model can be printed out by inputting the 3D model file into the 3D printer.
And step 110, acquiring a multi-layer gray level picture according to the printing model file.
In this embodiment, by performing slicing processing on the print model file, a multi-layer grayscale picture is obtained, where the multi-layer grayscale picture includes a plurality of section pictures at different positions, referring to fig. 2, in this embodiment, step 110 further includes:
and 111, slicing the printing model file according to preset precision.
And step 112, acquiring a multi-layer gray image according to the slice-processed printing model file.
In this embodiment, when the preset precision is higher, the number of slices is larger, so that the number of generated multi-layer grayscale images is also larger, and the printed 3D model is more accurate; when the preset precision is lower, the number of slices is smaller, so that the number of generated multi-layer grayscale images is also smaller, and the precision of the printed 3D model is reduced. The slicing precision is different according to different preset precisions, and therefore the effect of controlling the 3D printing quality is achieved.
And 120, establishing a coordinate axis by taking the upper left corner of the multilayer gray-scale picture as a coordinate origin, and determining the line segment endpoint coordinates of each line segment in the coordinate axis in the multilayer gray-scale picture through traversal scanning.
In this embodiment, each picture in step 120 is processed, specifically, a coordinate axis is established for each picture, exemplarily, a lower frame of each picture is taken as an X axis, a left frame is taken as a Y axis, an upper left corner is taken as a coordinate origin, a coordinate axis is established, and each pixel point is taken as a coordinate unit. In the embodiment, the traversal scanning is to scan each picture from left to right or from top to bottom, so that the position coordinates of each line segment in each picture are determined, file saving is performed on all the line segment coordinates, a new file format cxdlp is generated, the position of image data is recorded after slicing, when packed data is the position where only graphic data is transmitted, subsequent equipment automatically identifies the position where the image data is recorded, and then each complete picture can be obtained.
And step 130, generating a printing file according to the line segment endpoint coordinates of each line segment in the coordinate axis for printing.
In this embodiment, the position coordinates of each line segment in step 120 are stored to generate a print file, where the print file is a 3D print model, and after the 3D model is created, a suitable print material is selected according to the physical and mechanical properties of the printed object. Many materials can be used for 3D printing, for example, SLA uses liquid photosensitive resin, LOM uses paper, metal film, plastic film, SLS uses thermoplastic, metal powder, ceramic powder. After the printed material is determined, an appropriate 3D printer is selected. Currently, 3D printers are classified into two categories, industrial-grade and desktop-grade (consumer-grade). The more well-known companies include 3D Systems, Stratasys, Formlabs, Hewlett packard, EOS, Israel Objet. Since the 3D printer has strict requirements for the printing material, researchers should select a suitable printer and printing material according to the research purpose, requirements and budget. In this embodiment, the specific printing manner is not limited in this embodiment.
The embodiment of the invention provides a file processing method applied to 3D printing, which comprises the following steps: acquiring an input printing model file; acquiring a multi-layer gray level picture according to the printing model file; establishing a coordinate axis by taking the upper left corner of the multilayer gray level picture as a coordinate origin and performing traversal scanning to determine the line segment endpoint coordinates of each line segment in the multilayer gray level picture in the coordinate axis; and generating a printing file according to the line segment endpoint coordinates of each line segment in the coordinate axis for printing. According to the file processing method applied to 3D printing provided by the embodiment of the invention, the sliced image data is stored in a coordinate point mode, so that the problem that the printing file occupies too much memory in the prior art is solved, and the effects of reducing resource occupation and being more widely applied are realized.
Example two
Fig. 3 is a file processing method applied to 3D printing according to a second embodiment of the present invention, which is further explained and supplemented to a part of contents on the basis of the first embodiment, and this embodiment is suitable for reducing a print file saving space in 3D printing, and specifically, the file processing method applied to 3D printing according to the second embodiment of the present invention includes:
and 200, acquiring the input printing model file.
And step 210, acquiring a multi-layer gray level picture according to the printing model file.
And step 220, establishing a coordinate axis for the coordinate origin according to the upper left corner of the multi-layer gray level picture.
And step 230, performing traversal scanning in any direction on the multi-layer gray level picture.
And 240, acquiring the line segment endpoint coordinates of each line segment in the multi-layer gray level picture in the coordinate axis.
In this embodiment, the difference from the first embodiment is that the cutting direction of each field of picture is not limited, for example, the cutting may be performed from left to right, or from left bottom to right top, and the multi-layer grayscale pictures are cut in multiple directions, so that the effect of improving the cutting accuracy when the picture pattern is irregular is achieved. Illustratively, the coordinates of the upper left corner of the image are (0,0), and first move downward by the height of the image, each time judging 1 pixel value, if there are consecutive pixels greater than 0 in (0,0) to (0, h), then store the start (sp) and end (ep) position coordinates, and then continue moving rightward until the end of the lower right corner (w, h) of the image, specifically, in an alternative embodiment, referring to fig. 4, step 240 includes:
and 241, acquiring the start point coordinate and the end point coordinate of each line segment in the multi-layer gray level picture.
And 242, determining the line segment endpoint coordinates of each line segment in the multi-layer gray level picture in the coordinate axis according to the starting point coordinates and the end point coordinates.
In this embodiment, the position of each line segment in the coordinate axis may be determined by the start point coordinate and the end point coordinate of the line segment in the print pattern, where the width of each line segment is one pixel point, for example, the start point coordinate is (1, 3), the end point coordinate is (1, 5), the line segment is a line segment with two pixel points in length and one pixel point in width. When the same line segment is composed of a plurality of line segments in the scanning process, the start point coordinates and the end point coordinates of the line segments are recorded simultaneously so as to determine the line segment, and the position of each line segment can be determined by acquiring the start point coordinates and the end point coordinates of each line segment, so that the data storage capacity is reduced.
In other alternative embodiments, referring to fig. 5, step 240 further comprises:
and 243, obtaining the position coordinates of each pixel point in each line segment in the multi-layer gray level picture.
And 244, determining the line segment endpoint coordinates of each line segment in the multi-layer gray level picture in the coordinate axis according to the position coordinates of each pixel point.
In this embodiment, when the image is an uneven or irregular collective image, it is difficult to determine the exact position of the image by the position coordinates of the line segments, so that the effect of determining the image coordinates is achieved by recording the position coordinates of each scanned pixel point. The effect of accurately determining the image coordinates in the complex geometric patterns is realized by determining the coordinates of each pixel point, and the identification precision is improved.
And step 250, generating a binary file according to the position coordinates of each line segment.
In this embodiment, the position coordinates of each line segment are packaged together with other files into a binary file, and the file contains data such as: the method comprises the steps of obtaining a total number of layers, an x resolution (pixel), a y resolution (pixel), a thumbnail (116x116rgb), a preview (290x290 rgb), a machine parameter x length, a machine parameter y length, a layer thickness, exposure time, lamp-out time(s), bottom layer exposure time(s), a number of bottom layers, a bottom layer lifting distance, a bottom layer lifting speed, a lifting distance, a lifting speed, a return speed, bottom layer light intensity PWM and light intensity PWM, analyzing a cxdlp file by a printer, obtaining relevant data by analyzing the cxdlp file by the 3D printer, saving a storage space and improving transmission speed by storing a print file as a binary file.
And step 260, generating a printing file according to the binary file for printing.
In this embodiment, referring to fig. 6, step 260 further includes:
and 261, converting the binary file into a printing file and performing exposure processing.
And 262, printing the exposed printing file.
In this embodiment, the 3D model can be printed out by inputting the exposed file and the original image of the 3D printing model restored into the 3D printer. If the 3D model has problems, the model can be repaired through model repair software, the number of available model repair software is large, the Geomagic Wrap software is generally considered to be more suitable for repairing the model, and STL format files which can be used for 3D printing can be exported.
The embodiment of the invention provides a file processing method applied to 3D printing, which comprises the following steps: acquiring an input printing model file; acquiring a multi-layer gray level picture according to the printing model file; establishing a coordinate axis according to the multilayer gray level picture and performing traversal scanning to determine the line segment endpoint coordinates of each line segment in the multilayer gray level picture in the coordinate axis; and generating a printing file according to the line segment endpoint coordinates of each line segment in the coordinate axis for printing. According to the file processing method applied to 3D printing provided by the embodiment of the invention, the sliced image data is stored in a coordinate point mode, so that the problem that the printing file occupies too much memory in the prior art is solved, and the effects of reducing resource occupation and being more widely applied are realized.
