Layers and surface finish
- [Instructor] When you create something with a 3D printer, you control how smooth the surface is when you set the height of each layer. How long your piece will take to print out also depends on layer height. As we'll see, how many solid top and bottom layers you'll need to use is affected by the layer height too. We've launched Cura and loaded an STL file that we use to demonstrate what happens and we change these settings. When you change layer height, a curved surface is smoother, but the print takes longer. First, we show how these affect the dome 20 millimeters in radius with 0.1 layer height. If we look at the lower right, we'll see they'll take 49 minutes to print. Now do the same thing for layer height of 0.3. Note how much faster it will be printing, just about a factor of three. Here's what the finished prints look like. In this model, most visible surfaces have perimeters but you get a bit of the top…
