Fig. 2 shows the schematic flow sheet of the 3D Method of printing of the present invention in an embodiment, this embodiment is with Illustrate as a example by the processing procedure of 3D printer 101.

As in figure 2 it is shown, the 3D Method of printing in the present embodiment includes:

Step S201: receiving the 3D model slice file that 3D print platform sends, described 3D model slice file includes Slice of data after 3D model data is cut into slices；

Step S202: described 3D model slice file is resolved, it is thus achieved that described slice of data；

Step S203: use the described slice of data obtained after resolving to carry out 3D printing.

Accordingly, 3D printer, when printing, is directly to carry out after 3D print platform obtains 3D model slice file 3D prints, and acquire from 3D print platform is the most sliced good slice of data, and 3D printer is without performing again For the sectioning of 3D model data, thus, it is not necessary to the knowledge of the operation 3D printer of specialty can be carried out 3D and prints, and carries High user carries out the convenience of 3D printing, the application of beneficially 3D printing technique, universal and development.

Wherein, the most stolen by others in order to ensure 3D model slice file, above-mentioned 3D model slice file can be encryption 3D model slice file.Now, in the above-mentioned mode that 3D model slice file is resolved, include described in encryption 3D model slice file is decrypted operation.

In actual applications, 3D print platform may be different to the cipher mode of 3D model slice file so that 3D The corresponding manner of decryption of printer there is also difference, is illustrated below in conjunction with wherein several ways.

In in one way in which, transmission can be encrypted to use asymmetrical encryption and decryption mode.Now, print at 3D Machine this locality can store the private key of this 3D printer, has the PKI of this 3D printer in 3D print platform storage.In the case, The 3D model slice file of above-mentioned encryption is that the 3D model using the PKI corresponding with the private key of this 3D printer to be encrypted is cut Sheet file.3D printer, when being decrypted, is that the described 3D model slice file using locally stored private key pair encryption enters Row decryption oprerations.

Wherein, the private key of 3D printer and the PKI of correspondence, can be 3D printer when this 3D print platform is registered, It is that it distributes unique public private key pair by 3D printer.The private key of 3D printer is stored in 3D printer originally by 3D printer Ground, the PKI of 3D printer is by 3D print platform record and storage.3D print platform is sending information to this 3D printer every time Time, all use this PKI to be encrypted, after 3D printer receives, be decrypted with the private key of oneself storage.3D printer is each Need, when 3D print platform sends information, all to use the private key oneself stored to be encrypted, after 3D print platform receives, use Corresponding PKI is decrypted.Wherein, can be with irregular to public, private key double secret key between 3D printer and 3D print platform It is updated, the risk being cracked with reduction.

In another mode, 3D print platform can be carried out by the interim double secret key 3D model slice file generated Encryption, thus obtain the 3D model slice file of above-mentioned encryption.In the case, 3D print platform also sends raw to 3D printer The Key production information of this key, 3D printer is become also to receive the Key production information that described 3D print platform sends；According to institute State Key production information and generate corresponding key；Then the described 3D model slice file using the key pair encryption of generation is carried out Decryption oprerations.

Wherein, 3D printer, 3D print platform generate the mode of key, can print at 3D by the way of agreement in advance Platform presets in 3D printer.When generating key based on Key production information, generate in order to generate the key of key Information can by use any possible in the way of determine.

One of which generates the mode of key, after 3D print platform can be by generating a random number, by this random number As Key production information, use the encryption key that this generating random number of predetermined key generating mode is corresponding, and add with this 3D model slice file is encrypted by decryption key.In the case, this random number can be sent to 3D printing by 3D print platform Machine, after 3D printer receives this random number, uses corresponding key generating mode close with the deciphering that this generating random number is corresponding Key, and with this decruption key, the 3D model slice file of encryption is decrypted.

Another generates the mode of key, and the information of 3D printer self can be generated by 3D print platform as key Information, generates corresponding encryption key with this Key production information.The information of 3D printer here self can be such as 3D The configuration information of printer, the uniqueness serial number etc. of 3D printer.

In the case, 3D printer is before receiving the 3D model slice file that 3D print platform sends, also by this locality The configuration information of the described 3D printer of storage is sent to described 3D print platform.Now, above-mentioned Key production information includes institute State the configuration information of 3D printer.In the case, 3D printer is receiving the 3D model slice literary composition that 3D print platform sends After part, can without from 3D print platform receive Key production information, directly using own local store configuration information as Key production information generates corresponding decruption key.

When sending the configuration information of 3D printer, it is also possible to the uniqueness serial number of this 3D printer is sent to 3D and beats Print platform.Now, above-mentioned Key production information can also include the uniqueness serial number of 3D printer.

On the other hand, can be when 3D printer print every time, 3D print platform is the 3D model slice of this encryption One disposable chained address of file generated, and this disposable chained address is fed back to this 3D printer.3D printer passes through This disposable chained address that 3D print platform provides obtains the 3D model slice file of above-mentioned encryption.Concrete passing through is disposable Chained address obtains the mode of file, can carry out to use any mode that is the most existing and that be likely to occur later.

After 3D printer 3D has printed, it is also possible to delete locally stored described 3D model slice file.To avoid The risk that data are distributed.On the other hand, after 3D has printed, it is also possible to delete above-mentioned Key production information, on avoiding State Key production information to be stolen.

Fig. 3 shows the schematic flow sheet of 3D Method of printing in another embodiment.In this embodiment, it is to beat with 3D Illustrate as a example by the processing procedure of print machine.
