Example one
Fig. 1 is a schematic flow diagram of a 3D printing method according to an embodiment of the present invention, where the 3D printing method according to the embodiment of the present invention may be implemented by a centralized control platform of a 3D printing system, and the centralized control platform may be integrated on a user personal computer (client) or may be operated by an independent device. As shown in fig. 1, a 3D printing method according to a first embodiment of the present invention includes:
and S110, acquiring the printing encryption information sent by the client.
Specifically, the printing encryption information sent by the client is formed after the printing information sent by the user during 3D printing, and includes a 3D printing file. Generally, printing encryption information sent by a client is firstly transmitted to a cloud platform, and then the cloud platform forwards the printing encryption information to a centralized control platform.
S120, decrypting the printing encrypted information to obtain printing information.
Specifically, the printing encryption information is decrypted by adopting a decryption method matched with the encryption printing information, so that the printing information contained in the printing encryption information is obtained, wherein the printing information comprises a 3D printing file.
Further, when the client sends the printing encryption information, a check value is generated based on the 3D printing file. After decrypting the printing encryption information, the centralized control platform stores the decrypted printing information locally, and meanwhile, verifies the verification value of the 3D printing file to ensure the integrity of the 3D printing file. And if the verification fails, notifying the client to print the file in the 3D mode again, namely notifying the client to regenerate and send the printing encryption information.
And S130, determining a target printer according to the printing information and a preset printer list.
Specifically, the preset printer list lists the models of all printers connected to the centralized control platform. When performing 3D printing, a user usually designates a specific printer, which is indicated by a model (referred to as a designated model) of the designated printer, and the decrypted printing information includes the designated model.
And comparing the designated model with the printer models in the preset printer list, and if the same printer models exist in the preset printer list, indicating that the printer of the designated model is connected with the centralized control platform, so that 3D printing can be performed, wherein the printer of the designated model is taken as a target printer. If the same printer model does not exist in the preset printer list, other suitable printers in the preset printer list can be selected as target printers, and at this time, the model of the target printer needs to be fed back to the client, so that the user knows which printer to perform the 3D printing operation.
Optionally, when the same printer model does not exist in the preset printer list, information that the printer of the specified model does not exist may be fed back to the client, and the preset printer list is presented to the user, so that the user reselects a printer from the preset printer list as the target printer.
S140, sending the printing information and the verification information to the target printer so that the target printer prints the printing information according to the verification condition of the verification information.
Specifically, before issuing a print job to a target printer, the centralized control platform automatically allocates a unique IP address to each accessed printer through a Dynamic Host Configuration Protocol (DHCP), where the IP address is a unique identity of each printer in a network. The printer actively connects with the centralized control platform after obtaining the IP address, and reports the attribute information (such as printer model, IP address, port number, type, etc.). After the connection is completed, the centralized control platform automatically generates a printer list and stores the printer list in a local database.
And generating the verification information according to the 3D file information needing to be printed. The decrypted printing information includes the attribute information of the target printer, and after the target printer is determined, the printing information and the verification information are sent to the target printer according to the attribute information (such as a port number, an IP address and the like) of the target printer. And the target printer conducts verification based on the verification information so as to verify the integrity of the printing information sent by the centralized control platform. If the verification is passed, the target printer performs 3D printing according to the printing information; and if the verification fails, the centralized control platform is informed to resend the printing information and the verification information.
According to the 3D printing method provided by the embodiment of the invention, the printing encryption information sent by the client is obtained; decrypting the printing encrypted information to obtain printing information; determining a target printer according to the printing information and a preset printer list; and sending the printing information and the verification information to the target printer so that the target printer prints the printing information according to the verification condition of the verification information. The 3D printing method provided by the embodiment of the invention can automatically issue the printing tasks to the printer, can quickly select the appropriate target printer through the preset printer list, does not need manual selection of a user, and improves the efficiency and flexibility of 3D printing. Meanwhile, the centralized control platform can automatically allocate IP addresses for the accessed printers, so that automatic network distribution of the printers is realized, and the difficulty of configuring the printer network by a user is reduced.
Example two
Fig. 2 is a schematic flow chart of a 3D printing method according to a second embodiment of the present invention, which is a further refinement of the first embodiment. As shown in fig. 2, a 3D printing method provided by the second embodiment of the present invention includes:
s201, obtaining printing encryption information sent by a client, wherein the printing encryption information is encrypted through an RSA public key.
Specifically, before sending the printing information to the centralized control platform, the client firstly sends a communication request to the cloud platform, the cloud platform forwards the communication request to the centralized control platform, and the centralized control platform generates an encrypted RSA public key and an RSA private key by using an RSA encryption algorithm after receiving the communication request. The centralized control platform keeps the RSA private key and sends the RSA public key to the cloud platform, and the cloud platform returns the RSA public key to the client. When the client sends the printing information, the RSA public key is used for encrypting the printing information to form printing encrypted information.
Further, the client generates an MD5(Message-Digest Algorithm) value based on the printing information, and the MD5 value is sent to the cloud platform together with the printing encryption information and then forwarded to the centralized control platform by the cloud platform.
S202, decrypting the printing encrypted information through a prestored RSA private key to obtain the printing information.
Specifically, when the centralized control platform generates the RSA public key through the RSA encryption algorithm, the RSA private key corresponding to the RSA public key is generated together, and the RSA private key is stored locally. After the centralized control platform obtains the printing encryption information, the printing encryption information is decrypted through a pre-stored RSA private key, and the printing information is obtained and stored locally. And, the MD5 value of the printing information is subjected to integrity check, if the check fails, error information is fed back to the client, and the client is informed to transmit the printing encryption information again.
S203, determining the printer designated by the user according to the printing information.
Specifically, the print information includes a printer model (referred to as a designated model) designated by the user, and a printer corresponding to the designated model is referred to as a user-designated printer.
And S204, if the user-designated printer is in a preset printer list, sending a printing application to the user-designated printer so as to receive the current running state of the printer fed back by the user-designated printer based on the printing application.
Specifically, whether the printer model is the same as the specified model is determined in the preset printer list, and if yes, the user specifies that the printer is in the preset printer list; if not, the user specifies that the printer is not a printer in the preset printer list. And if the printer specified by the user is in the preset printer list, sending a printing application to the printer specified by the user through a TCP/IP communication protocol so as to inquire the current running state of the printer specified by the user.
The current operation state of the printer refers to whether the printer is normally operated at the current time. The printer normally runs to show that the printer is currently in an online state, is connected with the centralized control platform through a network, has normal parameters (such as printing materials, storage space, states of all parts and the like), and can perform normal 3D printing operation. The printer abnormal state indicates an off-line state of the printer or a printer failure.
S205, if the current running state of the printer is normal running, the printer designated by the user is used as a target printer.
Specifically, if the current running state of the printer is normal running, the printer is designated by the user as a target printer for executing the 3D printing operation.
And S206, if the printer specified by the user is not in a preset printer list or if the current running state of the printer is an abnormal state, taking the printer which is in the normal running state and has the least printing task in the preset printer list as a target printer.
Specifically, if the printer specified by the user is not in the preset printer list or the current running state of the printer is an abnormal state, that is, it indicates that the printer specified by the user is not currently available, the printer capable of performing the 3D printing operation needs to be reselected. At this time, the printer with the current running state in the preset list being normal running and the least printing task is taken as the target printer, so that the 3D printing operation of the user can be executed in shorter time, and the time consumed for the user to manually select the target printer is saved. Meanwhile, after the target printer is determined, the model of the target printer needs to be fed back to the client.
And S207, sending the printing information and the verification information to the target printer so that the target printer prints the printing information according to the verification condition of the verification information.
Specifically, the print information is generated in conjunction with the target printer. In this embodiment, the verification information is an MD5 value generated based on the 3D file information to be printed in the print information. And sending the printing information and the verification information to the target printer so as to enable the target printer to perform the 3D printing operation. The target printer receives the printing information and stores the printing information locally, and meanwhile, the MD5 value is verified. And if the verification is passed, performing 3D printing operation according to the 3D file information needing to be printed in the printing information.
And S208, if the verification failing information fed back by the target printer is received, the printing information and the verification information are sent to the target printer again.
Specifically, if the MD5 fails, the target printer feeds back the verification failure information to the centralized control platform. And after receiving the verification failure information, the centralized control platform regenerates the MD5 value according to the printing information and retransmits the MD5 value and the printing information to the target printer.
Further, when the number of times of resending the printing information and the verification information exceeds the preset number of times, error information is fed back to the client to inform the user whether the 3D file information needing to be printed is wrong or not. Alternatively, when the number of times of resending the print information and the verification information exceeds the preset number of times, the operating state of the target printer is set to be abnormal, and the process returns to step S206 to redetermine the target printer.
And S209, acquiring the printing progress of the target printer in real time.
Specifically, the printing progress of the target printer is obtained in real time or fed back to the client to monitor the printing process. And when the printing fails, feeding back abnormal information to the client, and timely informing the user to investigate the reason of the printing failure. Therefore, the user can check the real-time state of the printer accessed to the network only at the client, the remote control of a large number of printers is realized, the space limitation is broken through, and the maintenance investment is reduced.
The 3D printing method provided by the embodiment of the invention can automatically issue the printing tasks to the printers, can quickly select the appropriate target printer through the preset printer list, does not need manual selection of a user, and improves the efficiency and flexibility of 3D printing. Meanwhile, the centralized control platform can automatically allocate IP addresses for the accessed printers, so that automatic network distribution of the printers is realized, and the difficulty of configuring the printer network by a user is reduced. In addition, a user can check the real-time state of the printer accessed to the network only at the client, so that remote control over a large number of printers is realized, the space limitation is broken through, and the maintenance investment is reduced.
