[0026] 在本实施例中提供了一种3D打印方法，图1是根据本发明实施例的3D打印方法的流程图，如图1所示，该流程包括如下步骤: [0026] Providing a 3D printing method in the present embodiment, FIG. 3D is a flowchart of a printing method of an embodiment of the present invention, shown in Figure 1, the process comprising the steps of:

[0027] 步骤S102，划分3D打印对象物体模型的边缘与内部； [0027] step S102, and the internal dividing edge 3D printing target object model;

[0028] 步骤S104，确定打印的层厚，其中，该层厚可以依据需求而定，例如，可以设定该层厚为0.1〜0.3mm ; [0028] step S104, to determine the printed layer thickness, wherein the layer thickness can be based on needs, for example, you can set the thickness of 0.1~0.3mm;

[0029] 步骤S106，以层厚逐层打印边缘的预定层数，需要说明的是，该预定层数也可以依据具体操作条件来设定，例如，该预定层数可以设定为10〜30层； [0029] step S106, the printing layer by layer with a layer thickness of the edge of a predetermined number of layers should be noted that the predetermined number of layers can also be set based on the specific operating conditions, for example, the predetermined number of layers can be set to 10~30 layer;

[0030] 步骤S108，将打印完的预定层数合并为一层打印内部。 [0030] step S108, the finished print of a predetermined number of layers merged into one print inside.

[0031] 通过上述步骤，将3D打印对象物体模型划分为边缘与内部，对边缘与内部分别打印，边缘采用逐层打印，能够实现打印的精度，内部合并预定层数打印，提高打印的速度，相对于相关技术中每层均按照相同的层厚打印，不能满足精度与速度兼顾的问题，通过采用上述处理，有效地达到了精度与速度同时兼顾的效果。 [0031] Through the above steps, the 3D object model into print objects with the internal edge of the edge of each print inside edge printing layer by layer, to achieve precision printing, printing layers of predetermined internal consolidation, improve the printing speed, with respect to the related art, the thickness of each layer according to the same print, can not satisfy both the accuracy and speed problems, by using the above-described processing, effective to achieve the accuracy and speed while taking into account the effect.

[0032] 划分3D打印对象物体模型的边缘与内部时，依据具体物体的形状结构不同，可以采用不同的处理，例如，可以采用比例的方式来确定，比如，确定3D打印对象物体模型的横截面向外预定比例为3D打印对象物体模型的边缘，该预定比例也可以依据具体物体要求而定，比如，对于精度要求高的物体可以将该比例设置为低一些，而对于精度要求稍微低一些，而要求速度更高时，可以将该预定比例设置得高一些；又例如，可以直接采用预定距离的方式，即确定3D打印对象物体模型的横截面边缘向内预定距离为3D打印对象物体模型的边缘。 [0032] When the dividing edges and interiors of 3D printing target object model, depending on the shape of the structure of a specific object can be used in different processes, e.g., be proportional way to determine, for example, to determine the cross-section of 3D printing target object model outwardly a predetermined proportion of the target object edge 3D printing model, the predetermined ratio can also be based on specific requirements of the object may be, for example, for high precision of the ratio of the object can be set to low, but slightly lower for the accuracy, while higher demands speed, the predetermined ratio is set to a high number; another example, directly by way of a predetermined distance, which determines the cross-sectional 3D model of the target object print edge inwardly a predetermined distance of the target object model 3D printing edge. 如，可以设置距离边缘的向内的距离为3mm时则认为是边缘，剩余的即为内部。 For example, you can set the distance inward from the edge of 3mm is considered when the edge is remaining inside.

[0033] 在采用以层厚逐层打印边缘的预定层数，以及将打印完的预定层数合并为一层打印内部的边缘与内部打印方式之前，还可以以预定层数为单位将边缘划分为预定组数；依据预定组数，采用边缘与内部打印方式重复打印边缘与内部直至完成3D打印对象物体。 [0033] Prior to using the printing layer by layer thickness of the edge of a predetermined number of layers, and the finished print of a predetermined number of layers merged into one print inside edge of the internal printing method, a predetermined number of layers may also be divided into units of the edge is the number of a predetermined group; based on a predetermined set of numbers using the internal edge printing method print repeated until the completion of the internal edge 3D printing target object. 即可以对整个对象物体的打印过程分多个相同的步骤完成。 That process can print the entire object in several objects the same steps.

[0043] 针对相关技术中，快速成型机路径规划方法采用物体边界与内部相同的规划策略，打印速度无法得到有效提高。 [0043] For the related art, rapid prototyping machine path planning method using an object boundary and the same internal planning strategy, the print speed can not be effectively improved. 在相关技术中也给出了一些解决方案，例如，采用基于一定规则的变层厚方案，即每一层的厚度不一定一致，这样可以提高速度，但这样处理无法保证打印的精度。 In the related art also gives some solutions, for example, the use of variable thickness scheme based on certain rules that do not necessarily match the thickness of each layer, which can improve the speed, but this process can not guarantee the accuracy of print. 即在相关技术中采用每层边缘与内部相同的打印策略，即层厚相同的处理，要么用精度换速度，或者速度换精度，而采用每一层采用自适应层厚，又没有层间的规划，针对相关技术中上述问题，在本实施例中，提供了一种快速成型机打印路径规划方法，通过该方法，可以在不影响打印精度的前提下有效提高打印速度。 I.e., each layer in the related art using the internal edge of the same printing strategy, i.e., the same processing as the layer thickness, or by changing the speed of the accuracy, precision or speed change, and the use of adaptive thickness of each layer, the intermediate layer and no planning for the related art described above, in the present embodiment, there is provided a rapid prototyping machine print path planning method, by this method, without affecting the printing accuracy of the premise of effectively improve the printing speed.

[0045] 步骤S602，根据用户的需求将物体模型按照一定的层厚进行切分，例如，每一层层厚为xmm ； [0045] step S602, according to the needs of users in accordance with the object model of a certain thickness be segmented, for example, each layer having a thickness of xmm;

[0046] 步骤S604，将每一层靠近边缘的部分不做处理，对于内部的以N为单位进行合并，即每N层的内部合并成为一层； [0046] step S604, the part near the edge of each layer not treated for internal units combined with N, N that is the interior of each layer is merged into one;
