The specific steps of step S100 are as follows figure 2 Shown.
[0051] See figure 2 , Which is a specific flowchart of the step S100, and the step S100 specifically includes:
[0052] S101. Receive 3D model data uploaded by a user;
[0053] S102. Process the 3D model data and convert it into a universal printing code, and assign an encrypted file and an identification file to the universal printing code;
[0054] S103. Upload the universal printing code to a code repository of the cloud server, wherein the code repository stores a number of universal printing codes one-to-one corresponding to the 3D model.
[0055] In this embodiment, after receiving the 3D model data uploaded by the user, the 3D printing device converts and encrypts the data to ensure the confidentiality of the data, and then uploads the data to the cloud server for storage. In the specific implementation, the data is stored in the cloud The server is provided with a code storage library. The code storage library stores several general printing codes.

In actual use, if the user needs to update the 3D model data, he only needs to change The model data corresponding to the 3D model is uploaded to the 3D printing device provided by the present invention to store the model data, and because the 3D model data is not stored in the 3D printer, there is no need to update the 3D printer, only Connecting the 3D printer with the 3D printing equipment provided by the present invention, the 3D printer can call the universal printing code corresponding to all model data in the cloud server to print, thus facilitating the use of the 3D printer. In addition, it can also ensure that the printed The identity of parts improves efficiency.
[0056] S200: Receive a printing instruction from the 3D printer, and find a general printing code corresponding to the printing instruction from the cloud server.
[0057] In this embodiment, only the name of the 3D model is stored in the 3D printer. When printing, the user can input or select the name of the 3D model that needs to be printed, and then click Print. The 3D printer sends the printing instruction to the present invention. A 3D printing device, after receiving a printing instruction, the 3D printing device parses the printing instruction and calls out the corresponding universal printing code. The entire process is automatically completed at the back end without human operation, which is simple and convenient. Specifically, the specific flowchart of step S200 is as image 3 Shown.
[0058] See image 3 , Which is a specific flowchart of the step S200, and the step S200 specifically includes:
[0059] S201: Receive a printing instruction from a 3D printer and parse out a 3D model corresponding to the printing instruction;
[0060] S202: Find a universal printing code matching the 3D model corresponding to the printing instruction from the code storage library according to the code file ID corresponding to the 3D model.
[0061] In this embodiment, the printing instruction includes the name of the 3D model to be printed and the name and type of the 3D printer, and the name of the 3D model is used for the 3D printing device in the code repository of the cloud server Find out the universal printing code corresponding to the 3D model. The name and type of the 3D printer are used for the 3D printing equipment to identify the printer; the code repository can be updated at any time, and the user can directly delete the code storage of the cloud server One or more universal printing codes in the library. Of course, users can also add new universal printing codes to the code repository. Each universal printing code is unique and corresponds to a unique 3D model, ensuring that the 3D printer is sending printing instructions Then you can find the unique universal printing code to avoid printing confusion.
[0062] S300. Verify the 3D printer, and send the universal printing code to the 3D printer after the verification is completed, so that the 3D printer can perform 3D printing.
[0063] In this embodiment, in order to prevent illegally registered 3D printers from invoking data, the present invention also needs to verify the identity of the printer. Only when the verification is successful, the universal printing code is allowed to be sent to the 3D printer, thereby ensuring that the data cannot be illegally called. In addition, in order to adapt to various types of printers, the identification file is also used to identify the type of 3D printer, and further according to the type of 3D printer to send a suitable printing code to the 3D printer, to ensure the uniformity of printing quality, 3D printers in different geographical locations coordinately call work, print the same code, realize discrete manufacturing, and can reduce manual participation. Specifically, the specific flowchart of step S300 is as follows Figure 4 Shown.
[0064] See Figure 4 , Which is a specific flowchart of the step S300, and the step S300 specifically includes:
[0065] S301. Identify the 3D printer through an identity recognition file, and determine whether the identity of the 3D printer that sends the printing instruction meets the requirement;
[0066] S302: When the identity of the 3D printer meets the requirements, automatically modify the universal printing code according to the type of the 3D printer to adapt the universal printing code to the 3D printer;
[0067] S303. Send the modified universal printing code to the 3D printer to enable the 3D printer to perform 3D printing.
[0068] In this embodiment, the identity of the printer is recognized by the identity document preset on the universal printing code. The identity document in each universal printing code may be the same or different, and the user can customize it according to his needs. When the identification files of each universal printing code are the same, the user can set a 3D printer with a specified name or type to call all codes; when the identification files of each universal printing code are not the same, the user can specify a certain universal printing code only A specific 3D printer can be called, and another general printing code can only be called by another one or more 3D printers, thus further ensuring the confidentiality of the data; in addition, due to different geographical locations, different equipment, and different people, it is generally Each code must correspond to a model or model, so different people and different machines will cause problems when printing, so the present invention also judges the type of the 3D printer, and obtains the relevant parameters of the 3D printer through the type of the 3D printer. For example, the working size, consumables and other data of a 3D printer. Since different 3D printers may load different types of consumables, there will be problems when printing with one code. The present invention automatically modifies the general printing code after obtaining the type of the 3D printer Some of the contents in the universal printing code match the 3D printer, so that different types of 3D printers can be used together to ensure the uniformity of printing quality.
[0069] Preferably, when the identity of the 3D printer does not meet the requirements, a printing error prompt is issued to the printer or the printing error is directly displayed on the 3D printing device, thereby preventing illegal printers from calling data.
[0070] Furthermore, after the 3D printer obtains the universal printing code, it also needs to decrypt the encrypted file. Only a legal 3D printer can decrypt the encrypted file. Therefore, even if some 3D printers are using jailbreaks or other means to steal their identity Fortunately, after passing the verification, the universal printing code cannot be obtained further, which can further ensure the confidentiality of the data.

The 3D printer as the lower computer is legally registered as the 3D printing method provided by the present invention. After the lower computer of the equipment is realized, the universal printing code of the 3D model to be printed can be obtained through the 3D printing equipment, and then the 3D printing is realized, which is simple and convenient, and saves the storage space of the 3D printer.
