Description

Technical Field

The application relates to the technical field of three-dimensional printing, in particular to a method and a device for partially neglecting a 3D printing model, a method and a device for slicing the 3D printing model, a 3D printer, electronic equipment and a storage medium.

Background

When the existing slicing software processes a model, slicing is usually performed according to a preset path, and a generated slicing file (such as a Gcode file) contains path information of all slices, and the information can enable a 3D (three-dimensional) printer to perform printer control operation according to instructions in the slicing file. Taking the Gcode file as an example, the Gcode file contains instructions in G-code format, which is a language for describing how a 3D printer should print a job, and it generally stores instructions in plain text, each line representing a different command such as a printing speed of the printer, a temperature setting, and a moving position of a printing part.

However, the existing slicing software lacks an application scenario of ignoring a certain part model in some models, for example, a Gcode file is composed of a plurality of smaller part models, which are separated from each other, when the 3D printer auto leveling function is defective, a user initiates the model printing, and at this time, the model printed by the 3D printer cannot ensure that all the part models in the Gcode file are printed successfully, so that there may be some part models that are printed successfully, and some part models that are printed fail. In the whole printing process, once the printing fails, a user needs to make a printer calibration again and then reprint the model, so that consumable materials required by parts of the previous printing failure part are wasted, a large amount of printing time is consumed, and a series of safety accidents can be caused. Therefore, there is a need to solve this technical problem.

Furthermore, the terms "include" and variations thereof are to be interpreted as open-ended terms that mean "include, but are not limited to.

In order to solve the above technical problem, an embodiment of the present application provides a 3D printing model part neglecting method, as shown in fig. 1A, the 3D printing model part neglecting method may include the following steps S101 to S104:

step S101, a slice file is obtained, and a model to be printed corresponding to the slice file comprises a plurality of blocks; wherein, at least part of the code segments of the block are marked in front and behind.

In the step, the model to be printed can be composed of a plurality of part models, and each part model corresponds to each block, namely one part model corresponds to one block; the model to be printed may also be a part model, at least one of the blocks corresponding to a part of the part model.

The slice file includes code segments of one or several part models, i.e. code segments of several blocks, which can be executed to control the 3D printer to print each block. The code segments of at least part of the blocks are provided with marks at the front and the back, so that the printing can be omitted or skipped later.

Step S102, a model to be printed is displayed.

In the step, the model to be printed is displayed, the blocks corresponding to a plurality of part models can be displayed, or the blocks corresponding to one part model can be displayed, namely, a plurality of blocks included in the model to be printed can be displayed, so that a user can conveniently operate the blocks through a human-computer interaction interface, and follow-up neglecting printing or skipping printing is facilitated.

Step S103, receiving an instruction for canceling printing on the representation of a target block in a plurality of blocks, wherein the front and rear of a code segment corresponding to the target block are provided with marks.

In the step, the operation of canceling printing of the representation of the target block in each block displayed by the human-computer interaction interface by the user can be received, namely, the instruction of canceling printing of the representation of the target block in a plurality of blocks is received.

Step S104, according to the front and back identification of the code segments of the target block, when the 3D printer performs model printing based on the slice file, executing the code segments corresponding to the target block is ignored, and printing of the target block is ignored.

The to-be-printed model corresponding to the slice file in the embodiment of the application comprises a plurality of blocks, and the front and the rear of the code segments of at least part of the blocks are provided with the marks, so that the instruction of canceling printing of the target block can be performed based on the requirement, and when the 3D printer performs model printing based on the slice file, the execution of the code segments corresponding to the target block can be ignored, thereby omitting the printing of the target block, improving the printing efficiency and saving the printing resources.

In one possible implementation manner provided in the embodiment of the present application, before the slice file is obtained in the step S101, the method may include the following step A1:

step A1, embedding annotation information fields in the slice file in front of and behind the code segments of at least part of the blocks as front and behind identifications of the code segments of at least part of the blocks.

For example, the model to be printed includes a plurality of part models, each part model corresponding to each block, i.e., one part model corresponds to one block, and the plurality of part models including part models 1 to 10 may be embedded "in front of the code section of part model 1; part1 Start ", embedded" behind the code segment of Part model 1; part1 End "; embedding "in front of the code segment of the part model 2; part2 Start ", embedded" behind the code segment of Part model 2; part2 End "; similarly, insert "in front of the code segment of part model 10; part10 Start ", embedded" behind the code segment of Part model 10; part10 End).

As another example, the plurality of part models including part models a1 to a10 may be embedded "in front of the code segment of part model a 1; p1 Start ", embedded" behind the code segment of part model a 1; p1 End "; embedding "in front of the code segment of the part model a 2; p2 Start ", embedded" behind the code segment of part model a 2; p2 End "; and so on, embedding "in front of the code segment of part model a 10; p10Start ", embedded" behind the code segment of part model a 10; p10 End). This list is illustrative only and is not intended to limit the present embodiment.

In the embodiment of the present application, a possible implementation manner is provided, where step S103 above receives an instruction for canceling printing on a target tile in a plurality of tiles, and specifically may include the following step B1 or step B2:

and step B1, in the selected printing mode, receiving an operation of not selecting a target block in the plurality of blocks as an instruction for canceling printing on the representation of the target block.

In the step, if a user selects a block in the selected printing mode, a code segment corresponding to the block is indicated to be executed; if the user does not select the block, the representation will directly ignore the code segment corresponding to the block.

And step B2, receiving a selection operation of a target block in the plurality of blocks in the printing cancellation mode as an instruction for canceling printing of the target block.

In this step, if the user selects the target block in the cancel print mode, it means that the code segment corresponding to the target block will be directly ignored.

In this embodiment, the user may flexibly perform the operation of canceling printing on the target tile according to the actual requirement, so as to facilitate subsequent neglecting printing or skipping printing.

In the embodiment of the present application, a possible implementation manner is provided, where step S104 above ignores execution of a code segment corresponding to a target block when a 3D printer performs model printing based on a slice file according to front and rear identifiers of the code segment of the target block, so as to ignore printing of the target block, and specifically may include steps C11 and C12 below:

step C11, determining the code segments of the target block according to the front-back identifiers of the code segments of the target block;

and step C12, when the 3D printer performs model printing based on the slice file, executing the code segment corresponding to the target block is ignored.

According to the embodiment, the code segments of the target block can be determined according to the front and rear identifications of the code segments of the target block, and when the 3D printer performs model printing based on the slice file, the execution of the code segments corresponding to the target block is directly ignored or skipped, so that the printing efficiency can be improved, and the printing resources can be saved.

In one possible implementation manner provided in the embodiment of the present application, the front and rear of the code segment corresponding to the target block have identifiers, which may be the front and rear of the code segment of each print layer including the target block. Therefore, model neglect printing can be carried out according to the front and back identifications of the code segments of each printing layer of the target block, and finer model control is achieved.

In the embodiment of the present application, a possible implementation manner is provided, where step S104 above ignores execution of a code segment corresponding to a target block when a 3D printer performs model printing based on a slice file according to a front-back identifier of the code segment of the target block, so as to ignore printing of the target block, and specifically may include the following step C21:

and step C21, when the 3D printer performs model printing based on the slice file, and when the front identifier of the front and rear identifiers of the code segments corresponding to the target block is read, the execution of the code segments corresponding to the target block is ignored based on the rear identifier of the front and rear identifiers of the code segments corresponding to the target block.

According to the embodiment, when the 3D printer performs model printing based on the slice file, and when the front identifier of the front identifier and the rear identifier of the code segment corresponding to the target block are read, the execution of the code segment corresponding to the target block is directly skipped based on the rear identifier of the front identifier and the rear identifier of the code segment corresponding to the target block, so that the printing efficiency can be improved, and the printing resources can be saved.

In the embodiment of the present application, a possible implementation manner is provided, when each part in the model is printed to a certain height, at this time, a user can sense which part in the model is printed successfully and which part is printed failed, but the 3D printer does not know, in order to solve this technical problem, the camera may be combined to realize the advanced sensing of the part with failed printing, and specifically the method may include the following steps D1 to D3:

step D1, acquiring the outline of the printed model through a camera;

step D2, comparing the contour of the printed model with the contour in the slice file, and if the similarity of the comparison is smaller than a set threshold value, suspending printing and/or outputting a prompt;

and D3, responding to the instruction of canceling the printing of the corresponding block, and continuing to print the rest blocks.

In this embodiment, for the failed part model cancelled by the user, skip printing can be directly performed, and the remaining blocks continue to be printed, so that the printing efficiency is improved, and the printing resources are saved.

In the embodiment of the application, a possible implementation manner is provided, if the slice files comprise a plurality of slice files, in the process that the 3D printer performs model printing based on the plurality of slice files, if the printing of the blocks of the target slice files fails, the printing of the blocks of the target slice files is skipped, so that the printing efficiency is improved, and the printing resources are saved.

Based on the same inventive concept, the embodiment of the present application provides a slicing method of a 3D printing model, as shown in fig. 1B, the slicing method of the 3D printing model may include the following steps S111 to S113:

step S111, a 3D model file is acquired.

In this step, the 3D model file may be specifically an online 3D model file of the network, or a local 3D model file uploaded by the user. The 3D model files are acquired in various modes, the acquired model files are richer, and the model acquisition efficiency can be improved.

And step S112, responding to a slicing request carrying slicing parameter information, and slicing the 3D model corresponding to the 3D model file.

In this step, the slice parameter information may be slice block information, such as 9 blocks or 12 blocks, etc., which is only illustrative and not limiting in this embodiment.

If the 3D model corresponding to the 3D model file comprises a plurality of part models, the slice parameter information can comprise connection information of each part model, so that in the subsequent slicing process, marks can be embedded in front of and behind the code segments of each block according to the connection information of each part model, and the slice file is obtained. For example, if one part model is considered independent without any connection to the other parts, then identification may be made.

Step S113, the independent blocks are identified according to the slice parameter information, and the marks are embedded in the front and the back of the code segments of at least part of the independent blocks, so that the slice file is obtained.

According to the embodiment, in the slicing process, the independent blocks can be accurately and efficiently identified according to slice parameter information, and the marks are embedded in the front and the rear of the code segments of at least part of the independent blocks to obtain the slice file, so that the instruction for canceling printing of the target block can be subsequently performed based on the requirement, and when the 3D printer performs model printing based on the slice file, the execution of the code segments corresponding to the target block can be ignored, so that the printing of the target block is ignored, the printing efficiency can be improved, and the printing resources are saved.

In one possible implementation manner, the embedding of the identification before and after the code segment of the at least partial independent block comprises embedding the identification before and after the code segment of each printing layer of the at least partial independent block;

step S111 above obtains a 3D model file, specifically may be receiving the 3D model file, displaying a 3D model corresponding to the 3D model file, obtaining a local marking instruction for the 3D model, and performing local block marking; in one embodiment of the present application, the local marking instruction may refer to that after the 3D model is displayed on the screen, a user defines a dividing line through touch or man-machine interaction of a mouse, so that the 3D model is artificially divided, and the divided boundaries are marked, so that the boundaries can be used as independent blocks and can be independently disposed in a subsequent process, such as neglecting, etc.

Step S113 identifies an independent block according to slice parameter information, specifically, may identify an independent block according to connection information of each part in the 3D model file; or, identifying the independent blocks according to the local block marks in the 3D model file; the 3D model corresponding to the 3D model file herein includes a plurality of part models or a single part model.

The embodiment can identify the independent blocks according to the connection information of each part in the 3D model file, or identify the independent blocks according to the local block marks in the 3D model file, and then embed the marks in the front and back of the code segments of at least part of the independent blocks to obtain the slice file, the to-be-printed model corresponding to the slice file thus obtained comprises a plurality of blocks, the marks are arranged in the front and back of the code segments of at least part of the blocks, the instruction of canceling printing on the target block can be performed on the basis of the requirement subsequently, and when the 3D printer performs model printing on the basis of the slice file, the execution of the code segments corresponding to the target block can be omitted, so that the printing on the target block is omitted, the printing efficiency can be improved, and the printing resources can be saved.

Having described various implementations of the various links of the embodiments shown in fig. 1A and fig. 1B, a method for partially omitting or skipping a model in 3D printing according to an embodiment of the present application will be further described below by using a specific embodiment, where a model to be printed is composed of a plurality of part models, and one part model corresponds to one block.

Existing slicing software lacks application scenarios that ignore or skip a certain part model in some models, which may be made up of several possibilities:

1.1A slice file, such as a Gcode file, is made up of multiple part models, separated from each other.

When the 3D printer automatic leveling function has defects, a user initiates model printing, and at the moment, the model printed by the 3D printer cannot ensure that all part models in the Gcode file are successfully printed, so that part models can be successfully printed, and part models can fail to be printed. In the whole printing process, once the printing fails, a user needs to make a printer calibration again and then reprint the model, so that consumable materials required by parts of the previous printing failure part are wasted, a large amount of printing time is consumed, and a series of safety accidents can be caused.

Part model skip solution: may be implemented in conjunction with slicing software and 3D printer firmware application software.

(1) Slicing software part technology implementation

Annotation information fields corresponding to different parts are embedded in the Gcode file generated by the slicing software, and the model to which the part belongs is identified through the annotation information fields, specifically, the annotation information fields are embedded in the front and the back of the code segments of each part model and used as the front and the back identifications of the code segments of each part model.

For example, see fig. 2, "; part1 Start "identifies the Start of the first Part of the Part,"; part1End "identifies the End of the first portion of the Part; "; part2 Start "identifies the Start of the second Part of the Part,"; part2 End "identifies the End of the second portion of the Part; "; part3 Start "identifies the Start of the third Part of the Part,"; part3 End "identifies the End of the third portion of the Part; and so on, different printing blocks can be distinguished through the identification, so that the 3D printer firmware can be used for identification and information extraction. The examples are illustrative only and are not intended to limit the present embodiments.

(2) 3D printer firmware application software technology implementation

According to the technical implementation of the slice software part in the step (1), the 3D printer firmware end needs to realize the model skip function which is developed by matching with the slice software, namely, a user can operate a man-machine interaction application such as a touch screen to support the selection or cancellation of printing of the blocks corresponding to the Gcode model, and the principle of selecting the printed or cancelled blocks is that the similar blocks in the Gcode model file are matched; part1 Start ","; part1End "in the annotation field.

In the selective printing mode, a certain block is selected, that is, the program executes the Gcode code corresponding to the certain block, otherwise, the block is directly skipped, and the Gcode code of the next block is executed. In the cancel print mode, when a certain block is selected, the block is directly skipped, and the Gcode code of the next block is executed. In this way, a model skip function can be implemented.

(3) Application scenario

(1) The user selects to pause printing, can select the skip function of one or more parts in the model file through the human-computer interaction application, and then resumes printing, triggering the application software logic of the part skip function.

(2) When the 3D printer prints a certain block, the material is broken, at the moment, the equipment is in a material breaking stop state, after the material is re-fed, a user can select the skip function of one or more parts in the model file through man-machine interaction application, and then printing is continuously resumed, and application software logic of the part skip function is triggered.

(3) After the 3D printer is powered off accidentally, a user can select the skip function of one or more parts in the model file through man-machine interaction application after restarting, and then resume printing, and the application software logic of the part skip function is triggered.

1.1.1 multiple part models of the same morphology exist in a single model.

In this scenario, the principle of part skipping is as part 1.1, and will not be described here again.

1.1.2 in combination with the technical scheme in 1.1, and the part model skipping is realized by camera and AI (artificial intelligence) recognition.

Aiming at the problems, the 3D printer needs to combine a camera and an AI technology to realize the advanced perception of the printing failure part, and particularly can combine the current mainstream graphic image recognition algorithm, such as fixed-point shooting of a model in the printing process, binarization of the image, comparison of image data with an original model image (such as a model image in a slice file) and other means to perceive the printing result in advance, feedback the result to a page of a model part skip function, and automatically filter the printing failure option of the part for a user, thereby reducing misoperation of the user.

1.2A 3mf file is composed of a plurality of Gcode files, the files being different from each other.

The 3mf file format is one of the main formats of future 3D printing files, and has the main advantages of small file size, large contained information amount, strong readability, intellectualization and the like. The 3mf file is essentially a compressed package composed of zip (file compression algorithm) formats, so a 3mf file may include multiple Gcode files (i.e., multiple parts, each part being a separate Gcode file) to be sequentially transferred to a 3D printer, and the 3D printer may parse the 3mf file format to obtain multiple Gcode model files. When printing is initiated, there are several solutions that can enable model part skipping:

1.2.1 sequentially opening each Gcode file according to the 3mf file information, and printing in sequence.

When printing of a certain Gcode file may fail, the user may choose to skip the current file and continue printing the next Gcode file. The benefit of this approach is that no distinction needs to be made by the comment block described in 1.1.

1.2.2A plurality of Gcode files are opened simultaneously according to the 3mf file information, and whether printing of the next file block is carried out is determined according to the blocks in the Gcode files.

When printing of a certain block in a certain file fails, the block corresponding to the file can be skipped, and the block in the next Gcode file can be continuously printed, and the method can be realized by combining slicing software, and the principle is 1.1 and is not repeated here.

And 1.2.3, realizing model skipping by combining the camera and the AI intelligent recognition.

The 3D printer needs to combine the camera and AI technology to realize the advanced perception of the printing failure part, and can specifically combine the current mainstream graphic image recognition algorithm, for example, the model is subjected to fixed-point shooting in the printing process, then the image is subjected to binarization, then the image data is compared with the original model image (such as the model image in a slice file) and other means to perceive the printing result in advance, the result is fed back to the page of the model part skip function, and the option of part printing failure is automatically filtered for a user, so that misoperation of the user is reduced.
