Description

一种3D打印方法、装置及设备 技术领域
本发明涉及计算机技术领域，尤其涉及的是一种3D打印方法、装置及设备。
背景技术
3D打印是一种以数字模型文件为基础，运用粉末状金属或塑料等可粘合材料，通过逐层打印的方式来构造物体的技术。
现有技术的3D打印的设计过程是：先通过计算机软件，再将建成的三维模型分区成逐层的截面，即切片，从而指导打印机逐层打印。打印机通过读取文件中的横截面信息，用液体状、粉状或片状的材料将这些截面逐层地打印出来，再将各层截面以各种方式粘合起来从而制造出一个实体。
现有技术中的3D方法是基于点、线、面，采用Maya、3dsmax等传统CAD软件进行。3D打印时，由于受到地球重力的影响，并不是所有的3D模型都可以进行3D打印，需要保证模型在打印过程中不可倒塌，并且每个瞬间都足够兼顾，因此需要者在构型时就想好如何去3D打印，否则很难生成合适的可打印文件。上述过程除了算法复杂，耗时外，往往最终还需要人眼复查一遍，导致及打印效率比较低。
发明内容
本发明提供了一种3D打印方法、装置及设备，能够提高3D和打印的效率。
本发明实施例第一方面提供了一种3D打印方法，包括：

本发明实中的3D物体模型是以方块(立方体)为基本单位，能够将以方块为基本单位的物体模型直接转换成3D打印文件，再将3D打印文件发送至3D打印机进行打印。因为方块本身不是单纯几何图形，而是有体积的粒子，3D 打印过程中打印的是以方块为基本的3D像素，在将3D模型转换成3D打印文件过程中不需要考虑当前模型是否适合3D打印，因此，本发明实施例中的3D打印方法能够节省3D打印文件计算过程中的计算量，提高计算速度，从而能够提高3D打印的效率。
结合第一方面，在第一方面的第一种可能的实现方式中，获取以方块为基本单位的物体模型包括：根据用户选择从预定应用场景中获取用户所选择的以方块为单位的物体模型。
结合第一方面的第一种可能的实现方式，在第一方面的第二种可能的实现方式中，根据用户选择从预定应用场景中获取用户所选择的以方块为单位的物体模型包括：根据用户选择从基于方块的3D软件应用中选取以方块为单位的3D对象作为以方块为单位的物体模型。
结合第一方面的任一种可能的实现方式，在第一方面的第三种可能的实现方式中，在将以方块为基本单位的物体模型转换成支持3D打印的3D模型文件之前包括：在以方块为基本单位的物体模型中增加支撑物。
因为本方案是在基于方块为基本单位的物体模型上增加支撑物，而方块比点线面为基础的不规则面更具稳定性，并且能够更方便计算增加支撑物的点，从而节省计算时间，提高3D打印时建模的效率。
结合第一方面的任一种可能的实现方式，在第一方面的第四种可能的实现方式中，在将以方块为基本单位的物体模型转换成支持3D打印的3D模型文件之前还包括：标注出物体模型中的中空面和不可见面。
在以方块为基本单位的物体模型上能够比点线面的物体模型上更快速和更精准的识别出不可见面和中空面，从而节省计算时间，提高3D打印时建模的效率，使得在打印时无需打印出不可见面，并去除中空面，可以节省材料成本。
结合第一方面的任一种可能的实现方式，在第一方面的第五种可能的实现方式中，在将以方块为基本单位的物体模型转换成支持3D打印的3D模型文件之前还包括：将物理模型的尺寸比例调整至可一次打印完的尺寸比例。
第二方面，本发明实施例提供了一种3D打印装置，包括：
3D模型获取模块，用于获取以方块为基本单位的物体模型，方块为等边 立方体；3D打印文件生成模块，用于将以方块为基本单位的物体模型转换成支持3D打印的3D模型文件；发送模块，用于将支持3D打印的模型文件发送至3D打印机进行打印。
结合第二方面，在第二方面的第一种可能的实现方式中，3D模型获取模块具体用于：根据用户选择从预定应用场景中获取用户所选择的以方块为基本单位的物体模型。
结合第二方面的第一种可能的实现方式，在第二方面的第二种可能的实现方式中，3D模型获取模块具体用于：根据用户选择从基于方块的3D软件应用中获取以方块为基本单位的3D对象作为以方块为基本单位的物体模型。
结合第二方面的任一种可能的实现方式，在第二方面的第三种可能的实现方式，装置还包括：3D模型第一处理模块，用于在以方块为基本单位的物体模型中增加支撑物。
结合第二方面的任一种可能的实现方式，在第二方面的第四种可能的实现方式，装置还包括：3D模型第二处理模块，用于标注出物体模型中的中空面和不可见面。
结合第二方面的任一种可能的实现方式，在第二方面的第五种可能的实现方式，装置还包括：3D模型第三处理模块，用于将物理模型的尺寸比例调整至可一次打印完的尺寸比例。
第三方面，本发明实施例还提供了一种3D打印设备，该3D打印设备包括处理器和存储器；其中，存储器用于存储程序代码，处理器调用存储器中的所述程序代码，以执行以下操作：
获取以方块为基本单位的物体模型，所述方块为立方体；将所述以方块为基本单位的物体模型转换成3D打印文件；将所述3D打印文件发送至3D打印机进行打印。
从以上技术方案可以看出，本发明实施例的方案具有如下有益效果：
本发明实中的3D物体模型是以方块(立方体)为基本单位，能够将以方块为基本单位的物体模型直接转换成3D打印文件，再将3D打印文件发送至3D打印机进行打印。因为方块本身不是单纯几何图形，而是有体积的粒子，在方块上增加支撑面，或去除中空面和不可见面变得十分容易，就如同2D打 印是打印的像素，3D打印其实是打印的以方块为基本的3D像素，因此在将3D模型转换成3D打印文件过程中不需要考虑当前模型是否适合3D打印，从而能够提高3D打印过程中的计算速度，提高3D打印的效率。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例，基于本发明中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
我的世界(minecraft)及Paracraft等模拟类软件中，是让每一个用户在三维空间中自由地创造和破坏不同种类的方块。用户在软件中的形象可以在单人或多人模式中通过摧毁或创造方块以创造精妙绝伦的建筑物和艺术，或者收集物品探索地图以完成软件的主线，在这类软件中，软件中的基本元素为方块。
这类软件的用户可能有需求将软件中创造的某些物品、人物等内容制作成现实中的物品，现在可以利用3D打印技术来实现。
本发明提供了一种3D打印方法，可大大减少3D时需要处理的数据量，提高计算速度，从而提高和打印效率。
本实施例中3D打印方法的执行主体为3D打印装置，该3D打印装置具体可以集成在软件客户端中，该客户端可以装载在终端中，该终端具体可以为智能手机、平板电脑、MP4(Moving Picture Experts Group Audio Layer IV，动态影像专家压缩标准音频层面)播放器、膝上型便携计算机和台式计算机等等。
请参阅图1，本发明实施例中3D打印方法的一个实施例包括：
101、获取以方块为基本单位的物体模型，所述方块为立方体；
本发明中的物理模型以方块为基本单元组成的3D模型，其中，方块为立方体，立方体的棱长可以根据具体应用场景及用户的需求进行自定义。
可以根据用户选择从预定应用场景中获取用户所选择的以方块为单位的物体模型，预定的应用场景具体可以是基于方块的3D软件，例如上述举例的我的世界(minecraft)及Paracraft等基于方块的模拟类软件中，预定的应用场景不限于基于方块的3D软件，还可以是其他的基于方块的应用程序。
以基于方块的3D软件为例，用户在软件过程中可以选取相应的3D对象，例如：软件中的装饰品、虚拟物体等物品，该3D对象即为用户选择的以方块为基本单位的物体模型。
获取以方块为基本单元的物体模型的方法有多种，可选的，作为另一种实现方式，可以将平面模型(例如2D模型)或其他以非方块为基本单位的3D模型(例如以点线面为基础的3D模型)转化成以方块为基本单位的模型来获得以方块为基本单位的物体模型。
可选的，作为另一种实现方式，也可以先将以方块为基础的模型以模型集合的形式存储在存储设备中，例如云端服务器。用户在3D打印时从模型集合中获取自己所要打印的打印模型。
102、将以方块为基本单位的物体模型转换成3D打印文件；
在获取到以方块为基本单位的物体模型后，将以方块为基本单位的物体模型转换成支持3D打印的文件，支持3D打印的文件格式一般是stl，也可以是 bfb格式。
103、将3D打印文件发送至3D打印机进行打印。
将以方块为基本单位的物体模型转换成支持3D打印的文件之后，将3D打印文件发送至3D打印机，由3D打印机进行切片获得多层截面信息，再将获得多层截面信息逐层打印。
本发明实中的3D物体模型是以方块(立方体)为基本单位，能够将以方块为基本单位的物体模型直接转换成3D打印文件，再将3D打印文件发送至3D打印机进行打印。因为方块本身不是单纯几何图形，而是有体积的粒子，在方块上增加支撑面，或去除中空面和不可见面变得十分容易，就如同2D打印是打印的像素，3D打印其实是打印的以方块为基本的3D像素，因此在将3D模型转换成3D打印文件过程中不需要考虑当前模型是否适合3D打印，因此，本发明实施例中的3D打印方法能够节省3D打印文件计算过程中的计算量，提高计算速度，从而能够提高3D打印的效率。
可选的，在将以方块为基本单位的物体模型转换成3D打印文件之前，还可以对物理模型进行处理，以使得转换后的3D打印文件更有利于3D打印。图2为本发明实施例中3D打印方法的另一种流程图，包括：
201、获取以方块为基本单位的物体模型；
步骤201的具体实施方法请参阅图1所示的实施例中的步骤101。
202、在以方块为基本单位的物体模型中增加支撑物；为了确保在3D打印过程中打印出来的模型不会倒塌，在将以方块为基本单位的物体模型转换成3D打印文件之前，先对3D模型进行分析处理，在3D模型中增加合适的支撑物。因为本方案是在基于方块为基本单位的物体模型上增加支撑物，而方块比点线面为基础的不规则面更具稳定性，并且能够更方便计算增加支撑物的点，从而节省计算时间。
203、移除或填充以方块为基本单位的物体模型中的中空面和不可见面；
另外，为了节省打印时的材料成本，在将以方块为基本单位的物体模型转换成3D打印文件之前，先根据方块的点阵分析出3D模型中的不可见面和中空面，在3D模型文件中标注出不可见面和中空面，以使得在打印时无需打印出不可见面，并去除中空面，从而可以节省材料成本。
204、将以方块为基本单位的物理模型的尺寸比例调整至可一次打印完的尺寸比例；
另外，可选的，为了使打印时打印机能够一次性将物理模型打印出来，在将以方块为基本单位的物体模型转换成3D打印文件之前，需要先调整物体模型的尺寸比例，使得该模型能够适合打印机进行打印。
可选的，在将以方块为基本单位的物体模型转换成3D打印文件之前，先获取该模块的打印精度，根据打印精度将以方块为基本单位的物体模型转换成3D打印文件。
需要说明的是，步骤202、步骤203和步骤204之间可以不限定执行顺序，可以先执行步骤202、再执行步骤203，再执行步骤204；可以先执行步骤203、再执行步骤202，再执行步骤204；也可以在执行步骤202和203的同时执行步骤204。
205、将以方块为基本单位的物体模型转换成3D打印文件；
206、将3D打印文件发送至3D打印机进行打印。
步骤205和步骤206的具体实施方法请参阅图1所示的实施例中的步骤102和步骤103，此处不做赘述。
