Understand the importance of layer thickness of 3D printing to printing, and how it affects the quality, appearance and printability of hand plate processing.

　　所有的制造过程都是一层一层的打印，所以打印层的厚度决定了打印的分辨率和质量，类似于电视或电脑屏幕的分辨率，越薄的层分辨率越高。打印一个光滑的表面。所以缺点是打印时间会增加。重要的是设计者是看重外观还是能够引入快速打印。

　　All the manufacturing processes are layer by layer printing, so the thickness of the printing layer determines the resolution and quality of printing, similar to the resolution of TV or computer screen, the thinner the layer, the higher the resolution. Print a smooth surface. So the disadvantage is that the printing time will increase. It is important for designers to focus on appearance or to be able to introduce fast printing.

　　手板加工为什么分层厚度很重要。

　　Why layer thickness is very important in hand board processing.

　　对于某些打印技术，如SLS和PulJET，层的厚度并不重要，因为这种技术的分辨率对于大多数应用来说是足够的。对于FDM和SLA技术来说，层厚是一个重要的工艺参数，因为它影响到打印。时间，成本，外观和机械性能。

　　For some printing technologies, such as SLS and puljet, the thickness of the layer is not important because the resolution of this technology is sufficient for most applications. For FDM and SLA technologies, layer thickness is an important process parameter because it affects printing. Time, cost, appearance and mechanical properties.

　　有些手板加工技术，相同厚度的0.1mm和0.2mm的零件很难打印，但前者需要两倍的时间和更多的成本。

　　In some hand board processing technologies, parts with the same thickness of 0.1mm and 0.2mm are difficult to print, but the former requires twice the time and more cost.

　　在确定涂层厚度时，考虑更终的应用是很重要的。如果零件需要非常锋利的边缘或需要装配，需要更小的层厚度。

　　It is important to consider the final application when determining the coating thickness. If the part requires a very sharp edge or assembly, a smaller layer thickness is required.

　　层的厚度对夹角位置和曲率的影响更为明显。如果在设计中包含大量的曲线或角度，那么使用更小的层厚可以减少层的视觉冲击。

　　The influence of the thickness of the layer on the angle position and curvature is more obvious. If a large number of curves or angles are included in the design, a smaller layer thickness can reduce the visual impact of the layer.

　　垂直分辨率和层厚对垂直方向的影响主要体现在平滑度上。当厚度为0.1mm时，纹理显示在侧面。当厚度为0.2mm时，纹理变得更加明显，当各部分相互锁接或连接，且表面紧密结合时，纹理变得更加明显。

　　The influence of vertical resolution and thickness on vertical direction is mainly reflected in smoothness. When the thickness is 0.1mm, the texture is displayed on the side. When the thickness is 0.2mm, the texture becomes more obvious. When the parts are locked or connected with each other and the surface is closely connected, the texture becomes more obvious.

　　打印失败的可能性。对于某些印刷工艺，当层厚较小时，可能不利于印刷。对于DLP技术，使用0.1mm进行层状厚度打印的可能性是0.025mm的三倍。这是因为树脂固化后会从数值凹槽中分离出来，这两层的视觉效果受到视觉效果的影响，不明显。

　　Possibility of printing failure. For some printing processes, when the layer thickness is small, it may not be conducive to printing. For DLP technology, it is three times more likely to use 0.1mm for layer thickness printing than 0.025mm. This is because the resin will be separated from the numerical groove after curing, and the visual effect of these two layers is affected by the visual effect, which is not obvious.

　　处理后，贴膜厚度也会影响处理后的工艺。如果模型在打印后经过抛光、清洗或喷漆，可以使用更大的板材厚度。

　　After treatment, the film thickness will also affect the process after treatment. If the model is polished, cleaned, or painted after printing, a greater sheet thickness can be used.
