Understand the importance of layer thickness of 3D printing to printing, and how it affects the quality, appearance and printability of hand plate processing.
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.
Why layer thickness is very important in hand board processing.
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.
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.
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.
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.
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.
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.
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.
