Identifying thin lines and walls
In Chapters 10 and 12, we discussed the quality and detail we could expect from common types of 3D printing techniques, such as FFF, FDM, and SLA. As discussed, the resolution achievable by a 3D printer is typically defined as the layer height, and the smaller the layer, the smoother the print and the more detailed it will be.
But what about resolution in the other dimensions? Layer height is a factor in the vertical dimension, or Z, and we should also be concerned with how small our printers can create lines and walls in our design. Let’s say we want to create a ring, for example, as shown in Figure 13.7:
Figure 13.7: The Ring shape in Tinkercad
The Ring shape is shown in Figure 13.7, and initially, we might not question whether or not this can be 3D printed. But something we need to check in our design before attempting to 3D print our models is the wall thickness, which is highlighted in Figure 13.8:
