Description

一种3D打印设计、打印、许可方法，装置以及系统

背景技术
3D打印，既区别于纸张平面对文字的打印，又区别于传统方式通过铣刨等方式对产品的制造，是一种以立体逐层打印方式完成物品制造的系列技术与方法。具体的实现方式为：以计算机三维设计模型为蓝本，通过软件分层离散和数控成型系统，利用激光束、热熔喷嘴等方式将金属粉末、陶瓷粉末、塑料、细胞组织等特殊材料进行逐层堆积黏结，最终叠加成型，制造出实体产品。

本发明实施例提供的3D打印设计方法的基本流程请参见图1，主要包括：
101、3D打印设计系统确定目标打印文件；
在使用3D打印技术进行生产时，用户首先要通过3D打印设计系统设计目标打印文件，该目标打印文件的设计方法有很多，如通过计算机建模来进行设计等，本发明实施例中不做限定。3D打印设计系统确定该目标打印文件。
其中，该目标打印文件是一种记录了制造目标特点的数据形式，本发明实施例中不限定该目标打印文件的格式。
102、3D打印设计系统判断目标打印文件是否满足第一安全标准；
3D打印设计系统确定该目标打印文件后，判断该目标打印文件是否满足第一安全标准。3D打印设计系统判断该目标打印文件是否满足第一安全标准的方法有很多，将在后面的实施例中详述，本实施例中不做限定。
103、若目标打印文件满足第一安全标准，则3D打印设计系统将目标打印文件发送给3D打印系统。
在现阶段的3D打印技术中，3D打印设计系统在设计好目标打印文件后， 要将设计的目标打印文件发送给3D打印系统进行打印。因此本实施例中，若3D打印设计系统确定该目标打印文件满足第一安全标准，则3D打印设计系统将该目标打印文件发送给3D打印系统，使得3D打印系统按照所述目标打印文件进行打印。
其中，3D打印设计系统可以通过互联网将目标打印文件发送给3D打印系统、也可以通过与3D打印系统之间的独立数据通道将目标打印文件发送给3D打印系统、也可以通过磁盘拷贝数据的形式将目标打印文件发送给3D打印系统、也可以采取其他方法将目标打印文件发送给3D打印系统，本发明实施例中不做限定。
若3D打印设计系统确定该目标打印文件不满足第一安全标准，则3D打印设计系统可以不向3D打印系统发送该目标打印文件，也可以对该目标打印文件进行处理后再发送给3D打印系统，也可以采取其它方法，具体将在后面的实施例中详述，本实施例中不做限定。
本实施例中，3D打印设计系统设计好目标打印文件后，判断该目标打印文件是否满足第一安全标准，若目标打印文件满足第一安全标准，则将目标打印文件发送给3D打印系统，使得3D打印系统按照所述目标打印文件进行打印。通过对目标打印文件是否满足第一安全标准的判断，实现了3D打印设计系统对目标打印文件安全性的判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。
图1所示的实施例给出了本发明实施例提供的3D打印设计方法的基本流程，其中，3D打印设计系统在确定目标打印文件后，判断该文件是否满足第一安全标准，并根据判断结果确定是否将目标打印文件发送给3D打印系统。下面的实施例将在图1所示的实施例的基础上，进一步解释3D打印设计系统如何判断该文件是否满足第一安全标准，请参见图2，本发明提供的3D打印设计方法的又一实施例的基本流程包括：
201、3D打印设计系统确定目标打印文件；
步骤201与步骤101基本相同，此处不做赘述。
202、3D打印设计系统获取目标打印文件对应的目标产品属性；
3D打印设计系统所设计的目标打印文件均对应有目标产品，如：若3D 打印设计系统设计了关于汽车的目标打印文件，则该目标打印文件对应的目标产品就为汽车。同时，目标产品有着自身的属性，该属性可以为：目标产品的原材料种类信息、目标产品的原材料精度信息、目标产品的制造工艺流程信息、目标产品的空间形状信息、目标产品的用途信息，也可以为其它方面的属性，此处不做限定。
本实施例中，3D打印设计系统获取目标打印文件对应的目标产品属性。
203、3D打印设计系统根据该目标产品属性，获取目标打印文件对应的目标产品类别；
3D打印设计系统获取了目标打印文件对应的目标产品属性后，就可以根据该目标产品属性，获取目标打印文件对应的目标产品类别，其中，目标产品类别用于表示所述目标打印文件的分类。
其中，根据该目标产品属性获取目标打印文件对应的目标产品类别的标准有很多，例如：根据目标产品属性中的目标产品的原材料种类来判断目标产品类别，若目标产品的原材料种类为铁，则目标产品类别为金属制品；若目标产品的原材料种类为聚乙烯，则目标产品类别为塑料制品。或，根据目标产品属性中的目标产品的用途来判断目标产品类别，若目标产品的用途为代步，则目标产品类别为交通工具；若目标产品的用途为承装液体，则目标产品类别为容器。3D打印设计系统也可以根据该目标产品的其它属性来获取目标打印文件对应的目标产品类别，也可以根据目标产品的多个方面的属性来获取目标打印文件对应的目标产品类别，此处不做限定。
其中，目标产品的类别也可以简单的分为安全类产品与非安全类产品。例如，若3D打印设计系统从目标产品属性中获知：该目标产品的原材料中包含违禁原料、或该目标产品的空间形状为武器等违禁品的形状、或该目标产品的制造工艺流程涉及到违禁品的制造工艺、或该目标产品用于可能危害公民的生命财产安全的行为活动，则3D打印设计系统确定目标产品类别为非安全类产品。3D打印设计系统也可以根据其他方面的目标产品属性确定目标产品类别为非安全类产品，或确定目标产品类别为安全类产品，此处不做限定。
204、3D打印设计系统根据产品类别与第一安全标准的对应关系，判断目标打印文件是否满足第一安全标准；
3D打印设计系统获取了目标打印文件对应的目标产品类别后，就可以进一步判断目标打印文件是否满足第一安全标准。其中，产品类别与第一安全标准之间有对应关系，如：金属制品对应满足第一安全标准、塑料制品对应不满足第一标准等。
获取产品类别与第一安全标准的对应关系的方法有很多，可以为人为设置，也可以为3D打印设计系统自发的从服务器获取，也可以3D打印设计系统被动的从服务器接受，也可以为其他方式，此处不做限定。3D打印设计系统根据产品类别与第一安全标准的对应关系，判断该目标产品类别对应的目标打印文件是否满足第一安全标准。
特别地，若步骤203中，产品类别只有安全类产品与非安全类产品，则3D打印设计系统根据产品类别与第一安全标准的对应关系，判断所述目标打印文件是否满足第一安全标准包括：若目标产品类别为安全类产品，则3D打印设计系统确定目标打印文件满足第一安全标准，若目标产品类别为非安全类产品，则3D打印设计系统确定所述目标打印文件不满足第一安全标准。
其中，若3D打印设计系统确定目标打印文件满足第一安全标准，则执行步骤205；
若3D打印设计系统确定目标打印文件不满足第一安全标准，则执行步骤206。

其中，为了防止目标打印文件等信息被篡改，影响到目标打印文件的安全性的判别，3D打印设计系统与3D打印系统之间的数据传输可以均经过非对称加密。
本实施例在图1所示的实施例的基础上对3D打印设计系统如何判断目标打印文件是否满足第一安全标准做出了细化，其中，3D打印设计系统确定了目标打印文件后，获取目标打印文件对应的目标产品属性，进而获取目标打印文件对应的目标产品类别，然后根据产品类别与第一安全标准的对应关系，判断目标打印文件是否满足第一安全标准，若满足，则将目标打印文件发送给3D打印系统。通过这样的方法，使得3D打印设计系统可以判断目标打印文件是否满足第一安全标准，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。
图2所示的实施例提供了一种方法，详细解释了3D打印设计系统如何判断目标打印文件是否满足第一安全标准。其中，3D打印设计系统确定了目标打印文件后，判断目标打印文件是否满足第一安全标准，若满足，则将目标打印文件发送给3D打印系统，若不满足，则执行其他操作。下面的实施例中将详细描述当3D打印设计系统确定目标打印文件不满足第一安全标准时，具体如何执行其他操作，请参见图3。本发明的又一实施例的基本流程包括：

305、3D打印设计系统向打印许可中心发送第一许可请求信息；
若3D打印设计系统确定目标打印文件不满足第一安全标准，则3D打印设计系统向打印许可中心发送第一许可请求信息。
其中，打印许可中心用于判断该打印许可中心接收到的请求信息是否符合特定的安全标准，若符合，则颁发该文件对应的打印许可，打印许可表示允许 3D打印系统按照所述目标打印文件进行打印。
其中，一个完善的3D打印系统可能包含不止一个打印许可中心。3D打印设计系统可以根据目标打印文件寻找对应的打印许可中心。
其中，第一许可请求信息用于向打印许可中心请求打印许可，该第一许可请求信息中可以包括：目标打印文件、或目标产品属性、或目标产品类别，也可以为其他信息，此处不做限定。
306、3D打印设计系统判断是否接收到许可中心发送的第一打印许可；
3D打印设计系统向打印许可中心发送第一许可请求信息后，该打印许可中心将判断第一许可请求信息是否满足第二安全标准，若满足，则向3D打印设计系统发送第一打印许可。3D打印设计系统判断是否接收到所述许可中心发送的第一打印许可。其中，第二安全标准为许可中心判断接收到的请求信息所对应的打印文件是否安全的标准。
其中，若3D打印设计系统确定接收到许可中心发送的第一打印许可，则说明打印许可中心确定所述第一许可请求信息满足第二安全标准，执行步骤307；
若3D打印设计系统确定没有接收到许可中心发送的第一打印许可，则说明打印许可中心确定所述第一许可请求信息不满足第二安全标准，执行步骤308；
307、3D打印设计系统将目标打印文件发送给3D打印系统；
若3D打印设计系统确定目标打印文件满足第一安全标准，或确定接收到许可中心发送的第一打印许可，则3D打印设计系统将目标打印文件发送给3D打印系统，使得3D打印系统按照所述目标打印文件进行打印。
308、3D打印设计系统执行其他操作。
若3D打印设计系统确定目标打印文件不满足第一安全标准，且3D打印设计系统确定没有接收到许可中心发送的第一打印许可，则3D打印设计系统执行其他操作，包括：3D打印设计系统不向3D打印系统发送该目标打印文件、或D打印设计系统对该目标打印文件进行处理后再发送给3D打印系统，也可以为其它操作，本实施例中不做限定。
其中，为了防止目标打印文件、许可请求信息或打印许可等信息被篡改， 影响到目标打印文件的安全性的判别，3D打印设计系统、打印许可中心与3D打印系统之间的数据传输可以均经过非对称加密。

401、3D打印设计系统接收许可中心发送的预判断打印许可，并保存该预判断打印许可；
许可中心要接收一个或多个3D打印设计系统发送的许可请求，因此该许可中心接收的数据量非常庞大，处理较多的数据会造成许可中心效率低下、服务器负荷过重等许多问题。因此，许可中心可以将预判断打印许可发送给3D打印设计系统，该预判断打印许可对应有预置种类的目标打印文件，具体可以对应具有某种目标产品属性的目标打印文件，如若该预判断打印许可对应目标产品的原材料种类为塑料的目标打印文件，则所有目标产品的原材料种类为塑料的目标打印文件均与该目标产品；也可以对应类别为目标产品类别的目标打印文件，如对应目标产品类别为安全类产品的目标打印文件。预判断打印许可对应的目标打印文件也可以为其他预置种类，此处不做限定。
3D打印设计系统接收许可中心发送的预判断打印许可，并保存该预判断打印许可。

若3D打印设计系统确定没有保存与目标打印文件对应的预判断打印许可，则执行步骤407；
407、3D打印设计系统向打印许可中心发送第一许可请求信息；
若3D打印设计系统确定定没有保存与目标打印文件对应的预判断打印许可，则向打印许可中心发送第一许可请求信息。
其中，打印许可中心用于判断该打印许可中心接收到的请求信息是否符合第二安全标准，若符合，则颁发该文件对应的打印许可，打印许可表示允许3D打印系统按照所述目标打印文件进行打印。
其中，第一许可请求信息用于向打印许可中心请求打印许可，该第一许可请求信息中可以包括：目标打印文件、或目标产品属性、或目标产品类别，也可以为其他信息，此处不做限定。
408、3D打印设计系统判断是否接收到许可中心发送的第一打印许可；
3D打印设计系统向打印许可中心发送第一许可请求信息后，该打印许可 中心将判断第一许可请求信息是否满足第二安全标准，并根据判断结果发送打印许可。3D打印设计系统判断是否接收到所述许可中心发送的第一打印许可。
其中，若3D打印设计系统确定接收到许可中心发送的第一打印许可，则说明打印许可中心确定所述第一许可请求信息满足第二安全标准，执行步骤409；
若3D打印设计系统确定没有接收到许可中心发送的第一打印许可，则说明打印许可中心确定所述第一许可请求信息不满足第二安全标准，执行步骤410。

若3D打印设计系统确定目标打印文件满足第一安全标准、或确定保存有与所述目标打印文件对应的预判断打印许可、或确定接收到许可中心发送的第一打印许可，则3D打印设计系统将所述目标打印文件发送给3D打印系统。
410、3D打印设计系统执行其他操作。
若3D打印设计系统确定目标打印文件不满足第一安全标准、且确定没有保存与所述目标打印文件对应的预判断打印许可、且3D打印设计系统确定没有接收到许可中心发送的第一打印许可，则3D打印设计系统执行其他操作，包括：3D打印设计系统不向3D打印系统发送该目标打印文件、或D打印设计系统对该目标打印文件进行处理后再发送给3D打印系统，也可以为其它操作，本实施例中不做限定。
其中，步骤401也可以位于步骤402至405中任一项之后，只要位于步骤406之前即可，本实施例中不做限定。
其中，为了防止目标打印文件、许可请求信息或打印许可等信息被篡改，影响到目标打印文件的安全性的判别，3D打印设计系统、打印许可中心与3D打印系统之间的数据传输可以均经过非对称加密。
图4所示的实施例提供了一种3D打印设计方法，使得3D打印设计系统可以根据预判断打印许可对目标打印文件进行安全性判别。其中，若3D打印设计系统确定目标打印文件不满足第一安全标准，则3D打印设计系统判断是否保存有与目标打印文件对应的预判断打印许可，若是，则所述3D打印设计系统将所述目标打印文件发送给3D打印系统。通过这种方法,实现了3D打 印设计系统与打印许可中心对目标打印文件安全性的判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。同时，由于3D打印设计系统在向打印许可中心发送第一许可请求信息前，先判断是否保存有与目标打印文件对应的预判断打印许可，若是则将所述目标打印文件直接发送给3D打印系统，使得部分安全判别操作在3D打印设计系统内就可以完成，减少了打印许可中心接收的许可请求数目与安全判别操作次数，进而减轻了打印许可中心的负荷，提高了对目标打印文件安全性判别的效率。
图4所示的实施例提供了一种方法，该方法可以提高对目标打印文件安全性判别的效率。下面的实施例将提供另一种3D打印设计方法，用于提高对目标打印文件安全性判别的准确度，请参阅图5，本发明提供的又一实施例的基本流程包括：

3D打印设计系统可以获取产品类别与第一安全标准的对应关系，并根据该对应关系判断目标打印文件是否满足第一安全标准。但是，在实际应用中，产品类别与第一安全标准的对应关系可能会由于政府政策、科技发展等原因而发生变化。例如按照原有的产品类别与第一安全标准的对应关系，某类刀具满足该第一安全标准，但是按照更新后的产品类别与第一安全标准的对应关系，某类刀具就满足该第一安全标准。若产品类别与第一安全标准的对应关系发生了变化，但3D打印设计系统没有更新该对应关系，那么3D打印设计系统根据未更新的对应关系所进行的判断的结果是不准确的。因此，3D打印设计系统需要时常更新产品类别与第一安全标准的对应关系。
本实施中，产品类别与第一安全标准的最新对应关系保存在目标服务器上，3D打印设计系统从打印许可中心获取目标服务器地址，所述目标服务器地址为目标服务器的地址。
512、3D打印设计系统访问该目标服务器地址，并从该目标服务器中下载 更新文件；
3D打印设计系统从打印许可中心获取目标服务器地址后，访问该目标服务器地址，并从该目标服务器中下载更新文件，所述更新文件用于更新产品类别与第一安全标准的对应关系。
513、3D打印设计系统根据更新文件更新产品类别与第一安全标准的对应关系。
3D打印设计系统从目标服务器中下载更新文件后，根据该更新文件更新产品类别与第一安全标准的对应关系。
其中，步骤511至513也可以位于步骤501至510中任一项之前，本实施例中不做限定。
其中，步骤511至513也可以每隔预置时常便执行一次，本实施例中不做限定。
其中，为了防止目标打印文件、许可请求信息或打印许可等信息被篡改，影响到目标打印文件的安全性的判别，3D打印设计系统、打印许可中心与3D打印系统之间的数据传输可以均经过非对称加密。
本实施例提供了一种3D打印设计方法，其中，3D打印设计系统根据产品类别与第一安全标准的对应关系对目标打印文件的安全性进行判别，并时常更新产品类别与第一安全标准的对应关系。通过这种方法,实现了3D打印设计系统与打印许可中心对目标打印文件安全性的判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。同时，由于3D打印设计系统时常更新产品类别与第一安全标准的对应关系，使得3D打印设计系统所获取的产品类别与第一安全标准的对应关系更具有实时性，根据产品类别与第一安全标准的对应关系对目标打印文件所做的安全性判别更加准确可信。
为了便于理解上述实施例，下面将以上述实施例的一个具体应用场景为例进行说明：
3D打印设计系统从许可中心接收到预判断打印许可，并保存该预判断打印许可。该预判断打印许可的内容为：用于警用用途的枪支满足该预判断打印许可，但是用于军用用途的枪支不满足该预判断打印许可。
用户使用该3D打印设计系统设计了一份小型枪支的打印文件。3D打印设计系统确定打印文件设计完成后，获取这份打印文件的目标产品属性，该属性中包括：设计的产品为枪支、枪支口径为5.8毫米、该枪支用于军事用途。由该属性可以获知，该打印文件设计的产品为枪支，由于枪支具有一定的危害性，故3D打印设计系统将该打印文件的目标产品类别划分为非安全类产品，并确定该打印文件不符合第一安全标准。于是3D打印设计系统判断是否保存有与该打印文件对应的预判断打印许可。由于该3D打印设计系统保存的预判断打印许可只许可警用用途，不许可军用用途，所以3D打印设计系统确定未保存有与该打印文件对应的预判断打印许可。因此，3D打印设计系统向打印许可中心发送第一许可请求信息，其中，第一许可请求信息的内容为该打印文件的目标产品属性。
打印许可中心经过安全性判别，认为该小型枪支可以被生产，所以打印许可中心向3D打印设计系统发送第一打印许可。3D打印设计系统接收到第一打印许可后，将该小型枪支的打印文件发送给3D打印系统。
3D打印设计系统每隔预置时长，就会从许可中心获取目标服务器地址，访问该目标服务器地址，并从目标服务器中下载更新文件，根据更新文件更新所述产品类别与第三安全标准的对应关系。

603、若3D打印系统确定接收到打印许可中心发送的第二打印许可，则打印目标打印文件。
若3D打印系统确定接收到打印许可中心发送的第二打印许可，则说明打印许可中心确定该第一许可请求信息满足第二安全性标准，即目标打印文件满足第二安全性标准，故3D打印系统打印所述目标打印文件。
其中，为了防止目标打印文件、许可请求信息或打印许可等信息被篡改，影响到目标打印文件的安全性的判别，3D打印设计系统、打印许可中心与3D打印系统之间的数据传输可以均经过非对称加密。

许可中心要接收一个或多个3D打印系统发送的许可请求，因此该许可中心接收的数据量非常庞大，处理较多的数据会造成许可中心效率低下、服务器负荷过重等许多问题。因此，许可中心可以将预判断打印许可发送给3D打印系统，该预判断打印许可对应有预置种类的目标打印文件，具体可以对应具有某种目标产品属性的目标打印文件，如若该预判断打印许可对应目标产品的原材料种类为塑料的目标打印文件，则所有目标产品的原材料种类为塑料的目标打印文件均与该目标产品；也可以对应类别为目标产品类别的目标打印文件，如对应目标产品类别为安全类产品的目标打印文件。预判断打印许可对应的目标打印文件也可以为其他预置种类，此处不做限定。

1007、3D打印系统向打印许可中心发送第二许可请求信息；
若3D打印系统确定目标打印文件不满足第三安全标准，则3D打印系统向打印许可中心发送第二许可请求信息。
其中，打印许可中心用于判断该打印许可中心接收到的请求信息是否符合特定的安全标准，若符合，则颁发该文件对应的打印许可，打印许可表示允许3D打印系统按照所述目标打印文件进行打印。
其中，第二许可请求信息用于向打印许可中心请求打印许可，该第二许可请求信息中可以包括：目标打印文件、或目标产品属性、或目标产品类别，也可以为其他信息，此处不做限定。

图10所示的实施例提供了一种3D打印方法，使得3D打印系统可以根据预判断打印许可对目标打印文件进行安全性判别。其中，若3D打印系统确定目标打印文件不满足第三安全标准，则3D打印系统判断是否保存有与目标打印文件对应的预判断打印许可，若是，则所述3D打印系统打印该目标打印文件。通过这种方法,实现了3D打印系统与打印许可中心对目标打印文件安全性的判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。同时，由于3D打印系统在向打印许 可中心发送第二许可请求前，先判断是否保存有与目标打印文件对应的预判断打印许可，若是则直接打印目标打印文件，使得部分安全判别操作在3D打印系统内就可以完成，减少了打印许可中心接收的许可请求数目与安全判别操作次数，进而减轻了打印许可中心的负荷，提高了对目标打印文件安全性判别的效率。
图10所示的实施例提供了一种方法，该方法可以提高对目标打印文件安全性判别的效率。下面的实施例将提供另一种3D打印方法，用于提高对目标打印文件安全性判别的准确度，请参阅图11，本发明提供的又一实施例的基本流程包括：

步骤1109、1110与步骤1009、1010基本相同，此处不做赘述。
1111、3D打印系统从打印许可中心获取目标服务器地址；
3D打印系统可以获取产品类别与第三安全标准的对应关系，并根据该对应关系判断目标打印文件是否满足第三安全标准。但是，在实际应用中，产品类别与第三安全标准的对应关系可能会由于政府政策、科技发展等原因而发生变化。例如按照原有的产品类别与第三安全标准的对应关系，某类刀具满足该第三安全标准，但是按照更新后的产品类别与第三安全标准的对应关系，某类刀具就满足该第三安全标准。若产品类别与第三安全标准的对应关系发生了变化，但3D打印系统没有更新该对应关系，那么3D打印系统根据未更新的对应关系所进行的判断的结果是不准确的。因此，3D打印系统需要时常更新产品类别与第三安全标准的对应关系。

其中，步骤1111至1113也可以每隔预置时常便执行一次，本实施例中不做限定。
其中，为了防止目标打印文件、许可请求信息或打印许可等信息被篡改，影响到目标打印文件的安全性的判别，3D打印设计系统、打印许可中心与3D打印系统之间的数据传输可以均经过非对称加密。
本实施例提供了一种3D打印方法，其中，3D打印系统根据产品类别与第一安全标准的对应关系对目标打印文件的安全性进行判别，并时常更新产品类别与第三安全标准的对应关系。通过这种方法,实现了3D打印系统与打印许可中心对目标打印文件安全性的二次判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。同时，由于3D打印系统时常更新产品类别与第三安全标准的对应关系，使得3D打印系统所获取的产品类别与第三安全标准的对应关系更具有实时性，根据产品类别与第三安全标准的对应关系对目标打印文件所做的安全性判别更加准确可信。
为了便于理解上述实施例，下面将以上述实施例的一个具体应用场景为例进行说明：
3D打印系统从许可中心接收到预判断打印许可，并保存该预判断打印许可。该预判断打印许可的内容为：用于警用用途的枪支满足该预判断打印许可，但是用于军用用途的枪支不满足该预判断打印许可。
用户使用3D打印设计系统设计了一份小型枪支的打印文件。3D打印系统从3D打印设计系统获取该打印文件，然后获取这份打印文件的目标产品属性，该属性中包括：设计的产品为枪支、枪支口径为5.8毫米、该枪支用于军 事用途。由该属性可以获知，该打印文件设计的产品为枪支，由于枪支具有一定的危害性，故3D打印系统将该打印文件的目标产品类别划分为非安全类产品，并确定该打印文件不符合第三安全标准。于是3D打印系统判断是否保存有与该打印文件对应的预判断打印许可。由于该3D打印系统保存的预判断打印许可只许可警用用途，不许可军用用途，所以3D打印系统确定未保存有与该打印文件对应的预判断打印许可。因此，3D打印系统向打印许可中心发送第二许可请求信息，其中，第二许可请求信息的内容为该打印文件的目标产品属性。
打印许可中心经过安全性判别，认为该小型枪支可以被生产，所以打印许可中心向3D打印设计系统发送第二打印许可。3D打印系统接收到第二打印许可后，将打印该打印文件，得到的目标产品为小型枪支。
3D打印系统每隔预置时长，就会从许可中心获取目标服务器地址，访问该目标服务器地址，并从目标服务器中下载更新文件，根据更新文件更新所述产品类别与第三安全标准的对应关系。

在图3至图5中任一幅图所示的实施例中，当3D打印设计系统确定目标打印文件不满足第一安全标准，3D打印设计系统会向打印许可中心发送第一许可请求信息。其中，第一许可请求信息用于向打印许可中心请求打印许可，该第一许可请求信息中可以包括：目标打印文件、或目标产品属性、或目标产品类别，也可以为其他信息。
因此，本实施例中，打印许可中心接收3D打印设计系统发送的第一许可请求信息。
1202、打印许可中心判断第一许可请求信息是否满足第二安全标准；
打印许可中心接收到3D打印设计系统发送的第一许可请求信息后，判断该第一许可请求信息是否满足第二安全标准。
1203、若打印许可中心确定第一许可请求信息满足第二安全标准，则打印许可中心向3D打印设计系统发送第一打印许可。
若打印许可中心确定第一许可请求信息满足第二安全标准，则认为3D打印设计系统所设计的目标打印文件较为安全，可以授权打印该目标打印文件。因此，打印许可中心向3D打印设计系统发送第一打印许可。该第一打印许可用于：允许所述3D打印设计系统将所述第一许可请求信息对应的目标打印文件发送给3D打印系统。
其中，若打印许可中心确定第一许可请求信息不满足第二安全标准，则打印许可中心可以不向3D打印设计系统发送第一打印许可，也可以采取其它操作，本实施例中不做限定。
其中，打印许可中心可以根据第一许可请求信息对应的目标产品属性、目标产品类别、或发送第一许可请求信息的3D打印设计系统的安全级别来判断第一许可请求信息是否满足第二安全标准，也可以采取其他方式来判断第一许可请求信息是否满足第二安全标准，本实施例中不做限定。其中，安全级别用于表示所述3D打印设计系统的安全性，安全级别越高的3D打印设计系统，其发送的请求信息就越容易被打印许可中心认为满足第二安全标准。
其中，为了防止目标打印文件、许可请求信息或打印许可等信息被篡改，影响到目标打印文件的安全性的判别，3D打印设计系统、打印许可中心之间的数据传输可以均经过非对称加密。
本实施例提供了一种3D打印许可方法，从打印许可中心的角度实现了对目标产品的管制。其中，打印许可中心接收3D打印设计系统发送的第一许可请求信息、判断第一许可请求信息是否满足第二安全标准、若满足，则向3D打印设计系统发送第一打印许可。通过这样的方法，实现了打印许可中心对目标打印文件安全性的判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。
图12所示的实施例给出了一种3D打印许可方法的基本流程，该方法通过判断第一许可请求信息是否满足第二安全标准，实现了打印许可中心对打印文件的安全性的判别。下面的实施例将提供一种新的3D打印许可方法，可以进一步加强对打印文件的安全管制，请参见图13，本发明又一实施例的基本 流程包括：
1301、打印许可中心接收3D打印设计系统发送的第一许可请求信息；
步骤1301与步骤1201基本相同，此处不做赘述。
1302、打印许可中心根据第一许可请求信息获取许可请求类别；
打印许可中心接收到3D打印设计系统发送的第一许可请求信息后，根据第一许可请求信息获取许可请求类别。其中，许可请求类别用于表示许可请求信息的分类。许可请求信息的分类方式可以有很多种，如按照用途分类，分为商用类、民用类或军用类；或按照目标产品的原材料分类，分为金属类、非金属类；或按照其它方式分类等。特别的许可请求类别也可以与目标产品类别的分类相同，也可以不同，此处不做限定。
1303、打印许可中心获取处理该许可请求类别所对应的许可请求信息的次数；
一个打印许可中心需要处理一个或多个3D打印设计系统或者3D打印系统发送的各种许可请求信息。打印许可中心接收这些许可请求信息，并判断这些请求信息是否满足第二安全标准。但是，第二安全标准的概念是非常灵活的。例如，针对特定类别的危害性较小的目标产品，如管制刀具等，政府会允许该类别的目标产品以较少的数量在市面上流通，但不允许该类别的目标产品以较大的数量在市面上流通。因此，打印许可中心获取到许可请求类别后，获取处理该许可请求类别所对应的许可请求信息的次数。
打印许可中心获取处理该许可请求类别所对应的许可请求信息的次数的方法有很多，包括：打印许可中心对处理的不同类别的许可请求信息进行计数，每处理一次许可请求信息，就将该许可请求信息所对应的许可请求类别的计数值加1，并将计数结果保存在存储器中，在需要获取处理该许可请求类别所对应的许可请求信息的次数时，从存储器中获取。打印许可中心获取处理该许可请求类别所对应的许可请求信息的次数也可以为其他方法，本实施例中不做限定。
1304、打印许可中心判断处理所述许可请求类别所对应的许可请求信息的次数是否达到预置次数；
为了限制特定类别的目标产品只能以较小的数量在市面上流通，本实施例 中，打印许可中心内设置有预置次数。打印许可中心获取处理该许可请求类别所对应的许可请求信息的次数后，判断获取的次数是否达到预置次数。
其中，打印许可中心处理的许可请求信息有多种类别，相应的，该预置次数也不必是一成不变的。较为危险的类别的许可请求信息，如对应的目标产品为枪支弹药的许可请求信息，其对应的预置次数应该较小；而较为安全的类别的许可请求信息，如对应生活用品的许可请求信息，其对应的预置次数应该较大。具体可以为：所有的类别的许可请求信息都对应相同的预置次数、或若干个类别的许可请求信息对应相同的预置次数、或每种类别的许可请求信息所对应的预置次数都不同，不同类别的许可请求信息与预置次数的关系也可以为其他形式，此处不做赘述。
其中，若打印许可中心确定处理所述许可请求类别所对应的许可请求信息的次数达到预置次数，则执行步骤1305；
若打印许可中心确定处理所述许可请求类别所对应的许可请求信息的次数没有达到预置次数，则执行步骤1306。
1305、打印许可中心不向3D打印设计系统发送第一打印许可；
若打印许可中心确定处理所述许可请求类别所对应的许可请求信息的次数达到预置次数，则说明打印许可中心已经对该类别的许可请求做出了较多的许可授权。为了避免该许可请求类别所对应的目标产品被更多的生产出来，打印许可中心不向3D打印设计系统发送第一打印许可。
1306、打印许可中心判断第一许可请求信息是否满足第二安全标准；
若打印许可中心确定处理所述许可请求类别所对应的许可请求信息的次数没有达到预置次数，则打印许可中心判断第一许可请求信息是否满足第二安全标准。
其中，若打印许可中心确定第一许可请求信息满足第二安全标准，则执行步骤1307；
若打印许可中心确定第一许可请求信息不满足第二安全标准，则执行步骤1308。
1307、打印许可中心向3D打印设计系统发送第一打印许可。
若打印许可中心确定第一许可请求信息满足第二安全标准，则认为3D打 印设计系统所设计的目标打印文件较为安全，可以授权打印该目标打印文件。因此，打印许可中心向3D打印设计系统发送第一打印许可。该第一打印许可用于：允许所述3D打印设计系统将所述第一许可请求信息对应的目标打印文件发送给3D打印系统。
1308、打印许可中心执行其他操作。
若打印许可中心确定第一许可请求信息不满足第二安全标准，则打印许可中心执行其他操作，包括：打印许可中心不向3D打印设计系统发送第一打印许可，也可以为其它操作，本实施例中不做限定。
其中，为了防止目标打印文件、许可请求信息或打印许可等信息被篡改，影响到目标打印文件的安全性的判别，3D打印设计系统、打印许可中心与3D打印系统之间的数据传输可以均经过非对称加密。
其中，打印许可中心可以根据第一许可请求信息对应的目标产品属性、目标产品类别、或发送第一许可请求信息的3D打印设计系统的安全级别来判断第一许可请求信息是否满足第二安全标准，也可以采取其他方式来判断第一许可请求信息是否满足第二安全标准，本实施例中不做限定。其中，安全级别用于表示所述3D打印设计系统的安全性，安全级别越高的3D打印设计系统，其发送的请求信息就越容易被打印许可中心认为满足第二安全标准。
本实施例提供了一种3D打印许可方法，从打印许可中心的角度实现了对目标产品的管制。其中，打印许可中心接收3D打印设计系统发送的第一许可请求信息、判断第一许可请求信息是否满足第二安全标准、若满足，则向3D打印设计系统发送第一打印许可。通过这样的方法，实现了打印许可中心对目标打印文件安全性的判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。同时，由于打印许可中心会判断处理所述许可请求类别所对应的许可请求信息的次数是否达到预置次数，若是则不向3D打印设计系统发送第一打印许可，使得打印许可中心只对预置次数以内的许可请求信息进行许可授权，实现了对目标产品的生产数量的控制，进一步加强了对打印文件的安全管制。
为了便于理解上述实施例，下面将以上述实施例的一个具体应用场景为例进行说明：
打印许可中心接收3D打印设计系统发送的第一许可请求信息，该第一许可请求信息为一份打印文件的目标产品属性，其中，该打印文件的目标产品为小型枪支，该目标属性包括：目标产品为枪支、枪支口径为5.8毫米、该枪支用于军事用途。
打印许可中心接收到第一许可请求信息之后，根据第一许可请求信息获取许可请求类别，得到许可请求类别为枪械类。此前，打印许可中心处理枪械类的许可请求信息共计345次，未达到预置次数500次，于是打印许可中心判断第一许可请求信息是否满足第二安全标准。其判断标准为：若第一许可请求信息中包括的枪支口径小于6毫米，则认为满足第二安全标准。所以打印许可中心认为第一许可请求信息满足第二安全标准，该打印文件可以被打印。于是打印许可中心向3D打印设计系统发送第一打印许可。
图12与图13所示的实施例提供了不同的3D打印许可方法，其中，若打印许可中心确定第一许可请求信息满足第二安全标准，则向3D打印设计系统发送第一打印许可。下面的实施例将提供另一种3D打印许可方法，其中，若打印许可中心确定第一许可请求信息满足第二安全标准，则向3D打印系统发送第二打印许可。请参见图14，本发明的又一实施例的基本流程包括：
1401、打印许可中心接收3D打印设计系统发送的第一许可请求信息；
在图3至图5中任一幅图所示的实施例中，当3D打印设计系统确定目标打印文件不满足第一安全标准，3D打印设计系统会向打印许可中心发送第一许可请求信息。其中，第一许可请求信息用于向打印许可中心请求打印许可，该第一许可请求信息中可以包括：目标打印文件、或目标产品属性、或目标产品类别，也可以为其他信息。
因此，本实施例中，打印许可中心接收3D打印设计系统发送的第一许可请求信息。
1402、打印许可中心判断第一许可请求信息是否满足第二安全标准；
打印许可中心接收到3D打印设计系统发送的第一许可请求信息后，判断该第一许可请求信息是否满足第二安全标准。
1403、若打印许可中心确定第一许可请求信息满足第二安全标准，则打印许可中心向3D打印系统发送第二打印许可。
若打印许可中心确定第一许可请求信息满足第二安全标准，则认为3D打印设计系统所设计的目标打印文件较为安全，可以授权打印该目标打印文件。因此，打印许可中心向3D打印系统发送第二打印许可。该第二打印许可用于：允许所述3D打印系统打印第一许可请求信息对应的目标打印文件。
其中，若打印许可中心确定第一许可请求信息不满足第二安全标准，则打印许可中心可以不向3D打印设计系统发送第二打印许可，也可以采取其它操作，本实施例中不做限定。
其中，为了防止目标打印文件、许可请求信息或打印许可等信息被篡改，影响到目标打印文件的安全性的判别，3D打印设计系统、打印许可中心与3D打印系统之间的数据传输可以均经过非对称加密。
其中，打印许可中心可以根据第一许可请求信息对应的目标产品属性、目标产品类别、或发送第一许可请求信息的3D打印设计系统的安全级别来判断第一许可请求信息是否满足第二安全标准，也可以采取其他方式来判断第一许可请求信息是否满足第二安全标准，本实施例中不做限定。其中，安全级别用于表示所述3D打印设计系统的安全性，安全级别越高的3D打印设计系统，其发送的请求信息就越容易被打印许可中心认为满足第二安全标准。
本实施例提供了一种3D打印许可方法，从打印许可中心的角度实现了对目标产品的管制。其中，打印许可中心接收3D打印设计系统发送的第一许可请求信息、判断第一许可请求信息是否满足第二安全标准、若满足，则向3D打印系统发送第一打印许可。通过这样的方法，实现了打印许可中心对目标打印文件安全性的判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。

打印许可中心接收3D打印设计系统发送的第一许可请求信息，该第一许可请求信息为一份打印文件的目标产品属性，其中，该打印文件的目标产品为小型枪支，该目标属性包括：目标产品为枪支、枪支口径为5.8毫米、该枪支用于军事用途。
打印许可中心接收到第一许可请求信息之后，判断第一许可请求信息是否 满足第二安全标准。其判断标准为：若第一许可请求信息中包括的枪支口径小于6毫米，则认为满足第二安全标准。所以打印许可中心认为第一许可请求信息满足第二安全标准，该打印文件可以被打印。于是打印许可中心向3D打印系统发送第二打印许可。
图12至图14所示的实施例中，许可中心均从3D打印设计系统接收第一许可请求信息。实际上，许可中心也可以从3D打印系统接收第二许可请求信息，请参见图15，本发明又一实施例的基本流程包括：
1501、打印许可中心接收3D打印系统发送的第二许可请求信息；
在图9至图11中任一幅图所示的实施例中，当3D打印系统确定目标打印文件不满足第三安全标准时，3D打印系统会向打印许可中心发送第二许可请求信息。其中，第二许可请求信息用于向打印许可中心请求打印许可，该第二许可请求信息中可以包括：目标打印文件、或目标产品属性、或目标产品类别，也可以为其他信息。
因此，本实施例中，打印许可中心接收3D打印系统发送的第二许可请求信息。
1502、打印许可中心判断第二许可请求信息是否满足第二安全标准；
打印许可中心接收到3D打印系统发送的第二许可请求信息后，判断该第二许可请求信息是否满足第二安全标准。
1503、若打印许可中心确定第二许可请求信息满足第二安全标准，则打印许可中心向3D打印系统发送第三打印许可。
若打印许可中心确定第二许可请求信息满足第二安全标准，则认为3D打印系统所要打印的目标打印文件较为安全，可以授权打印该目标打印文件。因此，打印许可中心向3D打印系统发送第三打印许可。该第三打印许可用于：允许所述3D打印系统打印第二许可请求信息对应的目标打印文件。
其中，若打印许可中心确定第二许可请求信息不满足第二安全标准，则打印许可中心可以不向3D打印系统发送第二打印许可，也可以采取其它操作，本实施例中不做限定。
其中，为了防止目标打印文件、许可请求信息或打印许可等信息被篡改，影响到目标打印文件的安全性的判别，3D打印设计系统、打印许可中心与3D 打印系统之间的数据传输可以均经过非对称加密。
其中，打印许可中心可以根据第二许可请求信息对应的目标产品属性、目标产品类别、或发送第二许可请求信息的3D打印设计系统的安全级别来判断第二许可请求信息是否满足第二安全标准，也可以采取其他方式来判断第二许可请求信息是否满足第二安全标准，本实施例中不做限定。其中，安全级别用于表示所述3D打印系统的安全性，安全级别越高的3D打印系统，其发送的请求信息就越容易被打印许可中心认为满足第二安全标准。
本实施例提供了一种3D打印许可方法，从打印许可中心的角度实现了对目标产品的管制。其中，打印许可中心接收3D打印设计系统发送的第二许可请求信息、判断第二许可请求信息是否满足第二安全标准、若满足，则向3D打印设计系统发送第三打印许可。通过这样的方法，实现了打印许可中心对目标打印文件安全性的判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。
为了便于理解上述实施例，下面将以上述实施例的一个具体应用场景为例进行说明：
打印许可中心接收3D打印系统发送的第二许可请求信息，该第二许可请求信息为一份打印文件的目标产品属性，其中，该打印文件的目标产品为小型枪支，该目标属性包括：目标产品为枪支、枪支口径为5.8毫米、该枪支用于军事用途。

上面的实施例给出了多种3D打印设计方法、3D打印方法以及3D打印许可方法，下面的实施例将详细介绍用于实现上述方法的装置，此处未详尽介绍的内容可参考上述方法中的介绍。

第一安全判断单元17023，用于根据产品类别与第一安全标准的对应关系，判断目标打印文件是否满足第一安全标准。
文件发送模块1703，用于当第一安全判断模块1702确定目标打印文件满 足第一安全标准时，将目标打印文件发送给3D打印装置，使得3D打印装置按照目标打印文件进行打印。
本实施例在图16所示的实施例的基础上对第一安全判断模块做出了细化，其中，文件确定模块1701确定了目标打印文件后，第一属性获取单元17021获取目标打印文件对应的目标产品属性，进而第一类别获取单元17022获取目标打印文件对应的目标产品类别，然后第一安全判断单元17023根据产品类别与第一安全标准的对应关系，判断目标打印文件是否满足第一安全标准，若满足，则文件发送模块1703将目标打印文件发送给3D打印装置。通过这样的方法，使得3D打印设计装置可以判断目标打印文件是否满足第一安全标准，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。
图17所示的实施例提供了一种装置，详细解释了第一安全判断模块。其中，文件确定模块1701确定了目标打印文件后，第一安全判断单元17023判断目标打印文件是否满足第一安全标准，若满足，则文件发送模块1703将目标打印文件发送给3D打印装置。下面的实施例中将提出另一种装置，用于详细描述当目标打印文件不满足第一安全标准时，如何采取相应操作，请参见图18。本发明的又一实施例1800的基本结构包括：

本实施例详细解释了当3D打印设计装置确定目标打印文件不满足第一安全标准时，具体如何执行其他操作。其中，若当第一安全判断模块1802确定目标打印文件不满足第一安全标准，则第一请求发送模块1803向3D打印许可装置发送第一许可请求信息，第一许可判断模块1804判断是否接收到3D打印许可装置发送的第一打印许可。若第一许可判断模块1804确定接收到3D打印许可装置发送的第一打印许可，则说明3D打印许可装置确定所述第一许可请求信息满足第二安全标准，文件发送模块1805将目标打印文件发送给3D打印装置，使得3D打印装置按照所述目标打印文件进行打印。本实施例所提供的方法实现了3D打印设计装置与3D打印许可装置对目标打印文件安全性的二次判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。
图18所示的实施例提供了一种3D打印设计装置，其中3D打印许可装置可以对接收到的文件进行安全判别。下面的实施例将在图18所示的实施例的基础上提供一种新的3D打印设计装置1900，该装置可以减少3D打印许可装置进行安全判别的任务量。请参见图19，本发明又一实施例1900的基本结构包括：
第一预置保存模块1901，用于接收3D打印许可装置发送的预判断打印许可，并保存该预判断打印许可；
文件确定模块1902，用于确定目标打印文件；

图19所示的实施例提供了一种3D打印设计装置，可以根据预判断打印许可对目标打印文件进行安全性判别。其中，若第一安全判断单元19033确定目标打印文件不满足第一安全标准，则第一预置判断模块1904判断是否保存有与目标打印文件对应的预判断打印许可，若是，则文件发送模块1907将目标打印文件发送给3D打印装置。通过这种方法,实现了3D打印设计装置与3D打印许可装置对目标打印文件安全性的判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。同时，由于在第一请求发送模块1905向3D打印许可装置发送第一许可请求 信息前，第一预置判断模块1904先判断是否保存有与目标打印文件对应的预判断打印许可，若是则文件发送模块1907将目标打印文件直接发送给3D打印装置，使得部分安全判别操作在3D打印设计装置内就可以完成，减少了3D打印许可装置接收的许可请求数目与安全判别操作次数，进而减轻了3D打印许可装置的负荷，提高了对目标打印文件安全性判别的效率。
图19所示的实施例提供了一种装置，可以提高对目标打印文件安全性判别的效率。下面的实施例将提供另一种3D打印设计装置2000，用于提高对目标打印文件安全性判别的准确度，请参阅图20，本发明提供的又一实施例的基本结构包括：

第一预置判断模块2004，用于当第一安全判断单元确定目标打印文件不满足第一安全标准时，判断第一预置保存模块是否保存有与该目标打印文件对应的预判断打印许可；
第一请求发送模块2005，用于当第一安全判断单元18023确定目标打印文件不满足第一安全标准时，或第一预置判断模块确定第一预置保存模块没有保存与目标打印文件对应的预判断打印许可时，向3D打印许可装置发送第一许可请求信息；
第一许可判断模块2006，用于判断是否接收到3D打印许可装置发送的第 一打印许可，该第一打印许可由3D打印许可装置确定第一许可请求信息满足第二安全标准时发送；
文件发送模块2007，用于：当第一安全判断模块2003确定目标打印文件满足第一安全标准、或当第一许可判断模块确定接收到3D打印许可装置发送的第一打印许可、或当第一预置判断模块确定第一预置保存模块保存有与目标打印文件对应的预判断打印许可时，将目标打印文件发送给3D打印装置，使得3D打印装置按照目标打印文件进行打印。
第一地址获取模块2008，用于从3D打印许可装置获取目标服务器地址，所述目标服务器地址为目标服务器的地址；
第一地址访问模块2009，用于访问目标服务器地址，并从所述目标服务器中下载更新文件；

本实施例提供了一种3D打印设计装置，其中，第一安全判断模块2003根据产品类别与第一安全标准的对应关系对目标打印文件的安全性进行判别，第一标准更新模块2010时常更新产品类别与第一安全标准的对应关系。通过这种方法,实现了3D打印设计装置与3D打印许可装置对目标打印文件安全性的判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。同时，由于第一标准更新模块2010时常更新产品类别与第一安全标准的对应关系，使得第一安全判断模块2003所使用的产品类别与第一安全标准的对应关系更具有实时性，根据产品类别与第一安全标准的对应关系对目标打印文件所做的安全性判别更加准确可信。
为了便于理解上述实施例，下面将以上述实施例的一个具体应用场景为例进行说明：
第一预置保存模块2001从3D打印许可装置接收到预判断打印许可，并保存该预判断打印许可。该预判断打印许可的内容为：用于警用用途的枪支满足该预判断打印许可，但是用于军用用途的枪支不满足该预判断打印许可。
用户使用该3D打印设计装置设计了一份小型枪支的打印文件。文件确定模块2002确定打印文件设计完成后，第一属性获取单元20031获取这份打印 文件的目标产品属性，该属性中包括：设计的产品为枪支、枪支口径为5.8毫米、该枪支用于军事用途。由该属性可以获知，该打印文件设计的产品为枪支，由于枪支具有一定的危害性，故第一类别获取单元20032将该打印文件的目标产品类别划分为非安全类产品，且第一安全判断单元20033确定该打印文件不符合第一安全标准。于是第一预置判断模块2004判断是否保存有与该打印文件对应的预判断打印许可。由于第一预置保存模块2001保存的预判断打印许可只许可警用用途，不许可军用用途，所以第一安全判断单元20033确定未保存有与该打印文件对应的预判断打印许可。因此，第一请求发送模块2005向3D打印许可装置发送第一许可请求信息，其中，第一许可请求信息的内容为该打印文件的目标产品属性。
3D打印许可装置经过安全性判别，认为该小型枪支可以被生产，所以3D打印许可装置向3D打印设计装置发送第一打印许可。第一许可判断模块2006接收到第一打印许可后，文件发送模块2007将该小型枪支的打印文件发送给3D打印装置。

图28所示的实施例提供了一种3D打印装置，可以根据预判断打印许可对目标打印文件进行安全性判别。其中，第二安全判断单元28033确定目标打印文件不满足第三安全标准，则第二预置判断模块2804判断是否保存有与目标打印文件对应的预判断打印许可，若是，则第二文件打印模块2807打印该目标打印文件。通过这种方法,实现了3D打印装置与3D打印许可装置对目标打印文件安全性的二次判别，进而实现了对目标产品的管制，解决了高危物品的生产难以管制的问题，保障了社会稳定与公民人身安全。同时，由于第二预置判断模块2804判断是否保存有与目标打印文件对应的预判断打印许可， 若是则第二文件打印模块2807直接打印目标打印文件，使得部分安全判别操作由第二预置判断模块2804就可以完成，减少了3D打印许可装置接收的许可请求数目与安全判别操作次数，进而减轻了3D打印许可装置的负荷，提高了对目标打印文件安全性判别的效率。

为了便于理解上述实施例，下面将以上述实施例的一个具体应用场景为例进行说明：
第二预置保存模块2901从3D打印许可装置接收到预判断打印许可，并保存该预判断打印许可。该预判断打印许可的内容为：用于警用用途的枪支满足该预判断打印许可，但是用于军用用途的枪支不满足该预判断打印许可。
用户使用3D打印设计装置设计了一份小型枪支的打印文件。第二文件获取模块2902从3D打印设计系统获取该打印文件，然后第二属性获取单元29031获取这份打印文件的目标产品属性，该属性中包括：设计的产品为枪支、 枪支口径为5.8毫米、该枪支用于军事用途。由该属性可以获知，该打印文件设计的产品为枪支，由于枪支具有一定的危害性，故第二类别获取单元29032将该打印文件的目标产品类别划分为非安全类产品，且第二安全判断单元29033确定该打印文件不符合第三安全标准。于是第二预置判断模块2904判断是否保存有与该打印文件对应的预判断打印许可。由于第二预置保存模块2901保存的预判断打印许可只许可警用用途，不许可军用用途，所以第二预置判断模块2904确定未保存有与该打印文件对应的预判断打印许可。因此，第二请求发送模块2905向3D打印许可装置发送第二许可请求信息，其中，第二许可请求信息的内容为该打印文件的目标产品属性。
3D打印许可装置经过安全性判别，认为该小型枪支可以被生产，所以打印许可中心向3D打印设计系统发送第二打印许可。第二许可判断模块2906确定接收到第二打印许可后，第二文件打印模块2907打印该打印文件，得到的目标产品为小型枪支。
该3D打印许可装置中，每隔预置时长，第二地址获取模块2908就会从3D打印许可装置获取目标服务器地址，第二地址访问模块2909访问该目标服务器地址，并从目标服务器中下载更新文件。第二标准更新模块2910根据更新文件更新所述产品类别与第三安全标准的对应关系。
