Layer height refers to the thickness of each individual layer of material deposited by a 3D printer during the printing process. This setting is typically adjusted within the slicer software, which translates a 3D model into instructions for the printer.
For Fused Deposition Modeling (FDM) printers, common layer heights range from 0.1 millimeters to 0.5 millimeters. A smaller layer height results in finer detail and a smoother surface finish, but it also increases print time. Conversely, a larger layer height leads to faster printing but may produce visible layer lines and a less refined surface.
Factors to consider when choosing a layer height:
- Desired level of detail: Smaller layer heights are ideal for intricate designs and intricate surfaces.
- Printing time: Smaller layer heights increase printing time significantly.
- Nozzle diameter: It is recommended that the layer height is between 25% and 80% of the nozzle diameter.
- Material properties: Some materials may require specific layer heights for optimal results.
Example:
Imagine a 3D printed object with a layer height of 0.2 millimeters. This means that each layer of the object is 0.2 millimeters thick, and the printer will stack these layers on top of each other until the final object is complete.
