Understanding layer height and resolution

Understanding layer height and resolution

- [Instructor] Let's talk about layer height, what it is and the impact it has on the appearance or resolution of your 3D printed object. Layer height is the measurement of the height of a single extruded plastic layer and it's measured in millimeters or microns. For example, 0.1 millimeters is equal to 100 microns. It's a common layer height which for reference is about the thickness of one to two sheets of paper. You'll see ranges from 60 to 400 microns for most FDM 3D printers. Compare these two prints. One has layers that are 300 microns and the other 100 microns. Sometimes you'll hear layer height equated with resolution or quality, marking prints as high or low quality. But while layer height is certainly a component of resolution, it's only part of the story. Low quality doesn't necessarily mean sloppy. It just means that the layers are more prominent which in many cases won't impact the end use of the design. Also consider that line width has an impact on appearance. If you…
