3D打印与创客 “手电筒”3D打印后处理 课件：手电筒3D打印后处理（中英）.pptx

手电筒创新设计与3D打印;3D打印机由于打印材料以及打印精度的不同要求，一般还需要对打印出来的作品进行简单的后期处理，如去除打印物体的支撑。如果打印精度不够，就会有很多毛边，或者出现一些多余的菱角，影响打印作品的效果，因此需要我们通过一系列的后期处理来完善作品。 ;3D printing post-processing ;3、细部修正，在打印精度不高时，打印出来的物体在细节上可能跟期望的有所偏差，需要自己使用工具进行一定的修正，一般使用3D打印专用笔刀进行毛刺和毛边的修正； 3. Detail correction. When the printing accuracy is not high, the printed object may deviate from the expected details, so it needs to be corrected by tools.Generally, 3D printing pen and knife is used to correct the burr and burr edges.;　　砂纸打磨可以用手工打磨或者使用砂带磨光机这样的专业设备。砂纸打磨是一种廉价且行之有效的方法，一直是3D打印零部件后期抛光最常用、使用范围最广的技术。 　　一般用FDM技术打印出来的对象往往有一圈圈的纹路，用砂纸打磨消除电视机遥控器大小的纹路只需15分钟。;常见的上色方式有:喷涂、刷涂、笔绘喷涂和刷涂操作简单，除了常见的喷漆，也有手板模型专用的喷笔、龟泵，龟泵适合_上底漆，喷笔适用于小型模型或模型精细部分的上色。 笔绘则更适台处理复杂细节，用到的颜料有油性和水性之分,应注意选择对应的模型漆稀释剂。上色可以采用十字交叉法，即在第一-层快干还没干时，上第二层新鲜颜料，第二层的笔刷方向和第一-层垂直。除了.上色技法，优质的颜料也非常关键，可以让模型更生动、历久弥新。;Common coloring methods include: spray painting, brush painting and their operations are simple. Besides common spray painting , there are also airbushes and turtle pumps for hand-plate models. Turtle pumps are suitable for priming, and airbushes are suitable for painting small models or fine parts of models. Pen painting is more suitable for handling complex details, and the pigments used are oily or water-based, so the corresponding model paint thinner should be selected.Coloring can be done with the cross crossing method, that is, Apply the second layer of fresh paint to the first layer before it is dry, and its brush direction is vertical with the first - layer.In addition to the coloring technique, quality paint is also crucial to make the model more vivid and lasting.;丙烯颜料acrylic color;喷漆笔 spray painting;;;
