Meanwhile, because the slice parameter of the present application is objectively determined according to the associated mapping relationship, compared with the slice parameter set by the user experience and subjectively, the slice parameter obtained based on the above-mentioned manner has a basis, is more reliable and more accurate, so that the printing quality can be effectively ensured.

[0035] In order for those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] Before the printing method provided by the embodiments of the present application is described in detail, one of the application scenarios involved in the embodiments of the present application will be briefly introduced.

[0038] 3D printing technology is a new manufacturing technology that can convert digital models into physical models, with the characteristics of rapid, customization, low cost, etc., and therefore has a wide range of applications in the fields of medical, aerospace, automotive, industrial design, etc. A key step in the printing technology is slicing. Specifically, the slicing process is: according to the slicing parameters, the 3D model is cut into a layer of two-dimensional graphics, and then these two-dimensional graphics are converted into instructions that can be recognized by the 3D printer. The accuracy of the above slicing parameters directly affects the printing quality and printing efficiency. However, the above slicing parameters currently mainly depend on the user to set according to their own experience, and the slicing parameters set by them are greatly influenced by subjective factors, making the slicing parameters have low reliability and low accuracy, so as to cannot guarantee the printing quality and printing efficiency.

[0039] ​To address the aforementioned issues, this application provides a printing method in which a server stores a mapping relationship between device parameters, consumable parameters, model parameters, and slicing parameters. Based on the parameters influencing slicing parameters indicated in this mapping relationship—device parameters, consumable parameters, and model parameters—the server determines the relevant parameters when it detects a printing command from the printing device. Accordingly, based on the obtained parameters and the mapping relationship, the target slicing parameters are intelligently and accurately determined. This enables the printing device to intelligently obtain the target slicing parameters corresponding to the current target device parameters, target consumable parameters, and target model parameters from the server, and to perform accurate slicing based on these target slicing parameters, thereby intelligently determining the corresponding target slicing file.

[0040] By intelligently generating and distributing target slice parameters as described above, users can obtain suitable target slice files without needing professional knowledge, achieving fully automated slicing operations. Furthermore, because this slicing operation eliminates the need for users to set slice parameters and manually transfer slice files to the printing device, one-click printing is possible, improving printing efficiency and user convenience. Moreover, since the slice parameters in this application are objectively determined based on correlation mapping relationships, compared to slice parameters subjectively set by users based on experience, the slice parameters obtained through this method are more reliable, accurate, and dependable, thus effectively ensuring print quality.

[0041] Secondly, a brief introduction will be given to the implementation architecture involved in the embodiments of this application.

[0042] In some embodiments, the server is a remote server, a distributed server, or a mobile terminal server. A remote server is a server located and capable of remotely communicating with the printing device, such as a cloud server. A distributed server is a server with a distributed architecture capable of communicating with the printing device. A mobile terminal server is a portable terminal server capable of communicating with the printing device; a mobile terminal server is, for example, a mobile phone, tablet, or personal computer, and has computing resources. Thus, by utilizing the computing resources of a mobile phone to execute the method of this application, the obtained sliced ​​file is directly transmitted to the target printing device via communication between the mobile phone and the target printing device. This improves the confidentiality of the sliced ​​file, avoids remote communication, and allows direct communication between the mobile terminal server and the printing device even in situations with poor internet signal, making it more convenient for users.

[0043] like Figure 2 The diagram shows a printing system, which includes a server 11 and a printing device 12 with 3D printing capabilities. The server 11 and the printing device 12 are connected via a wired or wireless network.

[0044] In some embodiments, the server 11 and the printing device 12 communicate through MQTT (Message Queuing Telemetry Transport) service protocol.

[0045] In some embodiments, the server 11 is a cloud server and the printing device 12 is a 3D printer.

[0046] As a specific implementation, the printing system specifically performs the following printing process Figure 3 as shown.

[0047] S1, the cloud server enables the MQTT service protocol to listen to a plurality of printing devices.

[0048] In some embodiments, each to-be-printed model has a corresponding identification mark, and each identification mark is associated with at least one printing device. The cloud server listens to and detects the identification mark of the to-be-printed model based on the MQTT service protocol. When a printing device associated with the to-be-printed model is detected, the printing device is used as a target printing device for printing the to-be-printed model. When a plurality of printing devices associated with the to-be-printed model are detected, the printing device with the highest priority among the plurality of printing devices is used as a target printing device for printing the to-be-printed model.

[0049] For example, the identification mark can include one or more of the following: a two-dimensional code mark, a bar code mark, and a digital code mark.

[0050] In other embodiments, each printing device is connected to a user terminal device of a user, and the printing device selected by the user based on an application on the user terminal device is used as a target printing device.

[0051] The user terminal can be an electronic device such as a mobile phone, a tablet computer, and a desktop computer.

[0052] In yet other embodiments, the printing device directly started by the user is used as a target printing device. In this way, the user only needs to click the "start printing" button on the selected printing device, and the following steps S2 to S8 are automatically implemented.

[0053] S2, when a printing instruction for a to-be-printed model is detected, a target printing device is determined, or when a target printing device is detected to be powered on and online, the cloud server of the cloud end automatically connects to the target printing device.

[0054] S3, when a printing instruction for a to-be-printed model is detected, the cloud server sends a parameter acquisition request to the target printing device based on the MQTT service protocol.

[0055] S4, the target printing device accepts the parameter acquisition request, and reads the target device parameter, the target consumable parameter and the target model parameter of the target printing device.

[0056] S5, the target printing device sends the target device parameter, the target consumable parameter and the target model parameter to the cloud server.

[0057] S6, the cloud server receives the target device parameter, the target consumable parameter and the target model parameter, and determines the corresponding target slicing parameter according to the target device parameter, the target consumable parameter and the target model parameter.

[0058] S7, the cloud server sends the target slicing parameter to the target printing device.

[0059] S8, the target printing device receives the target slicing parameter and performs printing according to the target slicing parameter.

[0060] In the above embodiment, the slicing process is automatically completed by the server of the cloud to automatically form the target slicing parameter, and the cloud server sends the target slicing parameter to the corresponding target printing device to start the printing device to perform printing. In this way, all necessary slicing parameters can be automatically prepared, and the user only needs to start the "start printing" button to automatically slice the target model using the determined target slicing parameter. After slicing, the slicing file is sent to the printer through the cloud, and then the printing function is started, so that the printing of the target model is completed.

[0061] For ease of understanding, the printing method provided by the present application is specifically introduced in combination with the drawings by taking the printing method applied to the above printing system as an example.

[0062] Figure 3 is a flow chart of a printing method according to an example embodiment, as shown in Figure 4 The printing method includes the following steps.

[0063] S31, the server determines the target printing device associated with the target model and acquires one or more types of parameters of the target device parameter, the target consumable parameter and the target model parameter of the target printing device in response to the printing instruction of the target model.

[0064] The target model parameter is a parameter indicating the printing accuracy of the target model.

[0065] Exemplarily, when the user selects one of the model precision modes: a high precision mode, a medium precision mode and a low precision mode, a layer thickness corresponding to the selected precision mode is generated. Understandably, the precision mode selected by the user is a target model parameter; and the corresponding layer thickness generated under the precision mode selected by the user is a target slice layer thickness in a target slice parameter associated with the target model parameter.

[0066] In another example, the user selects a fast printing mode and a slow printing mode. For example, in the fast mode, if it is identified that the model has a small layer-to-layer variation, a larger layer thickness is selected as the target slice parameter associated with the target model parameter; and in the slow mode, a smaller layer thickness is selected for printing as the target slice parameter associated with the target model parameter.

[0067] In another example, the user customizes a layer thickness, an exposure time and other target mode parameters, which are directly used as the target slice parameter or as a basis for the target slice parameter for subsequent adjustment.

[0068] The above-mentioned target device parameter is a device parameter of a target printing device, including a device type and a device identifier.

[0069] The above-mentioned target consumable parameter is a consumable parameter used in the target printing device, including a material type, a material color and a material performance parameter.

[0070] The above-mentioned target printing device associated with the to-be-printed model includes: determining at least one printing device associated with the to-be-printed model; selecting a printing device with the highest priority from the at least one printing device as the target printing device; or in response to a selection confirmation operation of the user on any one of the at least one printing device, determining the any one printing device confirmed by the selection confirmation operation as the target printing device.

[0071] The above-mentioned target printing device can be determined based on the user selection. Understandably, the target printing device is a printing device selected by the user from a plurality of printing devices.

[0072] Exemplarily, from the plurality of printing devices, a printing device that has been started in response to a user start instruction is selected as the target printing device.

[0073] The above-mentioned target printing device can also be automatically determined based on a server. Specifically, the server is provided with an association relationship between each to-be-printed model and at least one printing device, and each to-be-printed model is provided with a corresponding priority for the at least one printing device associated therewith. Based on this, the printing device with the highest priority is selected from the at least one printing device associated with the to-be-printed model as the target printing device.

[0074] S32, the server determines the slice parameter corresponding to the target device parameter, the target consumable parameter and the target model parameter as the target slice parameter according to the association mapping relationship between one or more of the device parameters, the consumable parameters and the model parameters and the slice parameters.

[0075] The association mapping relationship between one or more of the device parameters, the consumable parameters, the model parameters and the slice parameters includes one or more of the following mapping relationships: a corresponding relationship between the device parameters and the slice parameters in the device dimension, a corresponding relationship between the consumable parameters and the slice parameters in the consumable dimension, and a corresponding relationship between the model parameters and the slice parameters in the model precision dimension.

[0076] In an embodiment, the association mapping relationship between one or more of the device parameters, the consumable parameters, the model parameters and the slice parameters can be a mapping relationship conforming to the parameter characteristics and the association characteristics of the device parameters, the consumable parameters, the model parameters and the slice parameters, which is obtained based on the comprehensive experience of a person skilled in the art and experimental tests.

[0077] In another embodiment, the preset model is a neural network model for representing the association mapping relationship between one or more of the device parameters, the consumable parameters and the model parameters and the slice parameters. Specifically, the association mapping relationship between one or more of the device parameters, the consumable parameters, the model parameters and the slice parameters is a preset model trained according to one or more of the historical device parameters, the historical consumable parameters and the historical model parameters and the historical slice parameters.

[0078] In the preset model, one or more of the historical device parameters, the historical consumable parameters and the historical model parameters and the slice parameters are taken as a group of input samples, and the historical slice parameters are taken as corresponding output samples.

[0079] The specific model training process is as follows: first, an initial model representing the association mapping relationship between one or more of the device parameters, consumable parameters, model parameters, and slice parameters and the slice parameters is constructed. Then, multiple sets of input samples and corresponding output samples are collected. At the same time, the input samples are input into the initial model to obtain the slice output parameters output by the initial model, and based on the slice output parameters and the historical slice parameters in the corresponding output samples, a loss value is determined. When the loss value is not within the preset loss range, the model parameters of the initial model are adjusted. Then, the input samples are input into the initial model after the adjustment of the model parameters to obtain the slice output parameters output by the initial model after the adjustment of the model parameters, and based on the slice output parameters and the historical slice parameters in the corresponding output samples, the loss value is determined again. The training is sequentially cycled until the loss value is within the preset range, and the training is stopped. At the same time, the initial model with the model parameters corresponding to the loss value within the preset range is determined as the preset model.

[0080] Optionally, in order to avoid the interference of different printing modes on the accuracy of the preset model, different preset models corresponding to different printing modes are set, that is, the preset model includes multiple preset models, and each preset model in the multiple preset models corresponds to a printing mode. It can be understood that the target consumable parameters corresponding to the target printing device are different, which indicates that the target printing mode of the target printing device is different, so in order to ensure the accuracy of the output result based on the preset model, the target preset model corresponding to the target printing mode is selected from the multiple different preset models to determine the target slice parameter.

[0081] Based on this embodiment, the specific implementation process of S32 can be as follows: determining the target printing mode indicated by the target consumable parameters; obtaining the target preset model corresponding to the target printing mode according to the correspondence between the printing mode and the preset model; and inputting one or more of the target device parameters, target consumable parameters, and target model parameters into the target preset model to obtain the target slice parameter based on the target association mapping relationship between one or more of the device parameters, consumable parameters, and model parameters indicated by the target preset model and the slice parameters.

[0082] Optionally, in some embodiments, the specific implementation process of S32 can be as follows: inputting one or more of the target device parameters, target consumable parameters, and target model parameters into the target preset model to obtain the target slice parameter. In this way, when there is only one preset model, one or more of the target device parameters, target consumable parameters, and target model parameters are directly input into the preset model to obtain the target slice parameter, thereby improving the overall efficiency of slicing.

[0083] Optionally, in some embodiments, the S32 can be implemented as follows: by way of table lookup, for example, taking one or more of the target device parameters, the target consumable parameters and the target model parameters as a key, searching for a value corresponding to the key in a database of associated data as the target slicing parameter, thus, the automatic generation of the slicing parameter can be realized by smaller computer resources, and the overall efficiency of slicing can be improved.

[0084] The printing mode includes a fused deposition modeling (FDM) printing mode and a light curing printing mode.

[0085] In an embodiment, the preset model includes three sub-models. The first sub-model is configured to generate parameters of a device dimension in the corresponding target slicing parameter based on the input target device parameters; the second sub-model is configured to generate parameters of a consumable dimension in the corresponding target slicing parameter based on the input target consumable parameters; and the third sub-model is configured to generate parameters of a model precision dimension in the corresponding target slicing parameter based on the input target model parameters.

[0086] In some embodiments, the slicing parameter can directly include the device parameters and the model parameters, and cannot directly include the consumable parameters, that is, the slicing parameter includes parameters of three dimensions of the device parameters, the model parameters and the converted consumable parameters, wherein the parameters of the two dimensions of the device parameters and the model parameters can be directly selected and included in the slicing parameter without conversion; and the parameters of the consumable dimension are obtained by converting the consumable parameters. Based on this, the training of the preset model is mainly the training of the second sub-model.

[0087] The following further describes the difference in training of the consumable dimension parameters in the target slicing parameter in combination with two different printing modes.

[0088] For the fused deposition modeling printing mode, the target consumable parameters input by the second sub-model are the nozzle minimum printing temperature, the nozzle maximum printing temperature, the hot bed minimum temperature, the hot bed maximum temperature, the printing minimum speed, the printing maximum speed, the retraction distance, the retraction speed, the cantilever beam notch impact strength, the thermal deformation temperature, the melting point, and the water content, the minimum drying temperature, the maximum drying temperature, the diameter, the tensile strength, the elongation at break, the drying time, the bending strength, the bending modulus, the Young's modulus, the melt index, the minimum shrinkage and the maximum shrinkage of the consumable. The target slicing parameters of the consumable dimension output by the second sub-model are the extrusion head temperature, the hot bed temperature and the printing speed. Therefore, in the fused deposition modeling printing mode, the target slicing parameter includes the extrusion head temperature, the hot bed temperature and the printing speed.

[0089] For the light-curing printing mode, the target consumable parameters input by the second sub-model are resin code, minimum first-layer exposure time, maximum first-layer exposure time, minimum first-layer exposure time for color screen, maximum first-layer exposure time for color screen, minimum normal exposure time, maximum normal exposure time, minimum normal exposure time for color screen, maximum normal exposure time for color screen, minimum temperature, maximum temperature, minimum use wavelength, maximum use wavelength, minimum viscosity, maximum viscosity, minimum hardness, maximum hardness, minimum tensile strength, maximum tensile strength, minimum molding shrinkage, maximum molding shrinkage, minimum elongation at break, maximum elongation at break, minimum bending strength, maximum bending strength, minimum bending modulus, maximum bending modulus, minimum heat distortion temperature, maximum heat distortion temperature, and shelf life. The target slicing parameters of the consumable dimension output by the second sub-model are exposure time, lifting height, and lifting speed. Therefore, in the light-curing printing mode, the target slicing parameters include exposure time, lifting height, and lifting speed.

[0090] The output parameters based on the target consumable parameters are multiple parameters, and the second sub-model is set as a multi-output regression model to ensure the accuracy of the second sub-model.

[0091] Optionally, as an implementation, after obtaining one or more of the following parameters: target device parameters of a target printing device, target consumable parameters used on the target printing device, and target model parameters of a model to be printed, an adjustment box for adjusting the target model parameters is displayed; and in response to a user's confirmation indication of the adjustment of the target model parameters on the adjustment box, the target model parameters adjusted on the adjustment box are determined as the target model parameters for slicing processing.

[0092] In this implementation, in order to meet the personalized needs of users for model parameter settings, after the target device parameters, target consumable parameters, and target model parameters of the target printing device are determined, an adjustment box for adjusting the target model parameters is displayed, so that the user can adjust the model parameters according to his own printing needs. After the parameter adjustment is completed, in response to a user's confirmation indication of the adjustment of the target model parameters on the adjustment box, the target model parameters adjusted on the adjustment box are determined as the target model parameters for printing.

[0093] As a slice thickness adjustment manner, a preset slice thickness corresponding to the bevel angle of the to-be-printed model is obtained according to the correspondence between the bevel angle and the slice thickness; when the target model parameter indicates that the printing precision of the to-be-printed model is within the preset precision range, the preset slice thickness corresponding to the bevel angle of the to-be-printed model is determined as the target slice thickness in the slice processing of the to-be-printed model; the target slice parameter includes the target slice thickness; when the target model parameter indicates that the printing precision of the to-be-printed model is greater than the preset precision range, the preset slice thickness corresponding to the bevel angle of the to-be-printed model is reduced according to a preset adjustment rule to obtain the target slice thickness in the slice processing of the to-be-printed model; when the target model parameter indicates that the printing precision of the to-be-printed model is less than the preset precision range, the preset slice thickness corresponding to the bevel angle of the to-be-printed model is increased according to the preset adjustment rule to obtain the target slice thickness in the slice processing of the to-be-printed model.

[0094] The preset adjustment rule indicates that the precision difference between the printing precision and the preset precision and the adjustment thickness are positively correlated, and the corresponding target slice thickness is negatively correlated. It can be understood that the greater the precision difference between the printing precision and the preset precision, the greater the adjustment thickness, and the smaller the corresponding target slice thickness.

[0095] Specifically, the target slice thickness in the target slice parameter is adjusted according to different precision requirements of the to-be-printed model. The server first determines a preset slice thickness corresponding to the preset precision range according to the preset precision range. When the printing precision of the to-be-printed model meets the preset precision range, it is indicated that the printing precision requirement of the to-be-printed model is moderate, and the original preset slice thickness is used as the target slice thickness. When the printing precision of the to-be-printed model is greater than the preset precision range, it is indicated that the printing precision requirement of the to-be-printed model is higher, and the original preset slice thickness is reduced, and the reduced preset slice thickness is used as the target slice thickness. When the printing precision of the to-be-printed model is less than the preset precision range, it is indicated that the printing precision requirement of the to-be-printed model is lower, and the original preset slice thickness is thickened, and the thickened preset slice thickness is used as the target slice thickness.

[0096] S33, the server performs slice processing on the to-be-printed model according to the target slice parameter to obtain a target slice file.

[0097] In an embodiment, the above-mentioned target slice parameter forms a corresponding target slice file. The target slice file includes the target slice parameter. In this way, the target slice parameter is sent to the target printing device in the form of the target slice file in the above-mentioned steps.

[0098] S34, the server transmits the target slice file to the target printing device.

[0099] S35, the target printing device receives the target slice file transmitted by the server, and prints the model to be printed according to the target slice file.

[0100] According to an embodiment of S35, the target printing device receives the target slice file transmitted by the server, and the target slice file includes target slice parameters.

[0101] The target slice parameters include a target slice thickness.

[0102] According to the above embodiment, based on the parameters affecting the slice parameters indicated in the association mapping relationship: device parameters, consumable parameters and model parameters, when the server detects the printing instruction of the printing device, the relevant parameters are determined. Accordingly, according to the above acquisition of relevant parameters and the association mapping relationship, the target slice parameters are intelligently and accurately determined, so that the printing device can intelligently obtain the target slice parameters corresponding to the current target device parameters, target consumable parameters and target model parameters from the server, and accurately print based on the target slice parameters.

[0103] Therefore, the user does not need to have professional knowledge to obtain the adaptive target slice parameters, and the full-automatic slicing operation is realized. Moreover, because the user setting slice parameter step is omitted in the slicing operation process, the user no longer needs to manually transmit the slice file to the printing device, so one-key printing can be realized, the printing efficiency is improved, and the convenience of the user in the use process is improved. At the same time, because the slice parameters of the present application are objectively determined according to the association mapping relationship, compared with the slice parameters set by the user experience and subjectively, the slice parameters obtained based on the above method have a basis, are more reliable and more accurate, and thus the printing quality can be effectively ensured.

[0104] Optionally, as an embodiment, the target slice parameters further include a target placement angle. In order to ensure the printing quality, the target placement angle of the model to be printed in the printing process is accurately determined. Specifically, the contour shape and contour size of the model to be printed are obtained; the model to be printed is adjusted according to the contour shape and contour size, so that the target placement angle of the model to be printed in the slicing process is obtained; and the model to be printed is placed according to the target placement angle. Wherein, the preset support condition indicates that the support material used for support is less than the preset material range or the support occupies an area greater than the preset area range.

[0105] The determination method of the target placement angle is different in different application scenarios, and the specific determination process is described as follows.

[0106] In a first scenario, when it is determined that the target printing device performs a printing operation in a fused deposition modeling printing mode, the minimum support material is achieved by adjusting the area of the to-be-printed model adhered to the printing platform. Specifically, when it is determined that the target printing device performs a printing operation in a fused deposition modeling printing mode, the placing angle of the to-be-printed model is adjusted according to the contour shape and the contour size, and the adhered area of the to-be-printed model adhered to the printing platform under each placing angle is determined. The placing angle corresponding to the largest area of the adhered area under each placing angle is determined as the target placing angle, so that the placing angle corresponding to the largest area of the to-be-printed model adhered to the printing platform is determined as the target placing angle, so that the support force for supporting the to-be-printed model is minimized, thereby achieving the minimum support material used for support.

[0107] In a second scenario, when it is determined that the target printing device performs a printing operation in a light-curing printing mode, the minimum support material used for support is achieved by adjusting the overhanging area of the to-be-printed model. Specifically, when it is determined that the target printing device performs a printing operation in a light-curing printing mode, the placing angle of the to-be-printed model is adjusted according to the contour shape and the contour size, and a plurality of overhanging areas of the to-be-printed model under different placing angles are determined. The placing angle corresponding to the smallest overhanging area of the plurality of overhanging areas is determined as the target placing angle.

[0108] For any application scenario, in order to ensure the printing speed, the target placing angle is determined based on the following manner: first, a plurality of bounding boxes of the to-be-printed model under different placing angles are determined, and then the placing angle corresponding to the bounding box with the smallest thickness in the plurality of bounding boxes is determined as the target placing angle. The bounding box represents a cube composed of the minimum and maximum vertices of the to-be-printed model. The thickness of each bounding box is the cross-sectional thickness occupied by the bounding box in the vertical plane of the printing platform.

[0109] For example, the to-be-printed model is placed horizontally on the printing platform in the form of the smallest thickness to ensure the speed mode.

[0110] In order to realize the above functions, the printing material control device includes hardware structures and / or software modules corresponding to each function. Those skilled in the art should easily realize that the algorithm steps of each example described in combination with the embodiments disclosed herein can be realized in the form of hardware or a combination of hardware and computer software.
