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

　　所有的制造過程都是一層一層的打印，所以打印層的厚度決定了打印的分辨率和質量，類似于電視或電腦屏幕的分辨率，越薄的層分辨率越高。打印一個光滑的表面。所以缺點是打印時間會增加。重要的是設計者是看重外觀還是能夠引入快速打印。

　　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.

　　手板加工為什么分層厚度很重要。

　　Why layer thickness is very important in hand board processing.

　　對于某些打印技術，如SLS和PulJET，層的厚度并不重要，因為這種技術的分辨率對于大多數應用來說是足夠的。對于FDM和SLA技術來說，層厚是一個重要的工藝參數，因為它影響到打印。時間，成本，外觀和機械性能。

　　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.

　　有些手板加工技術，相同厚度的0.1mm和0.2mm的零件很難打印，但前者需要兩倍的時間和更多的成本。

　　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.

　　在確定涂層厚度時，考慮更終的應用是很重要的。如果零件需要非常鋒利的邊緣或需要裝配，需要更小的層厚度。

　　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.

　　層的厚度對夾角位置和曲率的影響更為明顯。如果在設計中包含大量的曲線或角度，那么使用更小的層厚可以減少層的視覺沖擊。

　　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.

　　垂直分辨率和層厚對垂直方向的影響主要體現在平滑度上。當厚度為0.1mm時，紋理顯示在側面。當厚度為0.2mm時，紋理變得更加明顯，當各部分相互鎖接或連接，且表面緊密結合時，紋理變得更加明顯。

　　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.

　　打印失敗的可能性。對于某些印刷工藝，當層厚較小時，可能不利于印刷。對于DLP技術，使用0.1mm進行層狀厚度打印的可能性是0.025mm的三倍。這是因為樹脂固化后會從數值凹槽中分離出來，這兩層的視覺效果受到視覺效果的影響，不明顯。

　　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.

　　處理后，貼膜厚度也會影響處理后的工藝。如果模型在打印后經過拋光、清洗或噴漆，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.
