Layer thickness refers to the height of each individual layer deposited during an additive manufacturing process, such as 3D printing. It's a crucial parameter influencing the final product's quality, printing time, and resolution. In essence, it's the vertical dimension of each layer that stacks to form the three-dimensional object.
Layer Thickness in 3D Printing
In 3D printing, layer thickness, often called layer height, directly impacts the print's appearance and properties. A thinner layer height generally results in smoother surfaces and higher detail resolution, but increases printing time. Conversely, a thicker layer height leads to faster prints but may exhibit visible layer lines and less detail. The optimal layer thickness depends on the printer, material, and desired outcome.

Examples of Layer Thickness: Common layer thicknesses in 3D printing range from 0.1 mm to 0.4 mm, with some printers capable of even finer or coarser layers.
-
Impact on Print Quality: Thinner layers produce smoother surfaces, while thicker layers are faster but show more visible layering.

Software Control: Software like PreForm (referenced in the provided links) allows users to adjust layer thickness according to their printing needs and materials. http://support.formlabs.com/

Relationship with Nozzle Diameter: The nozzle diameter and layer height are related; a guideline suggests the extrusion width should be at least 1.5 times the layer thickness. https://community.ultimaker.com/topic/1079-max-layer-thickness/
Layer Thickness in Other Contexts
The concept of layer thickness also extends beyond 3D printing. For example:
-
Printed Circuit Boards (PCBs): In PCB manufacturing, layer thickness refers to the thickness of each conductive layer within a multi-layer board. Standard thicknesses are commonly used. https://www.reddit.com/r/PrintedCircuitBoard/comments/1ep70na/4_layer_pcb_layer_thickness/
-
Cell Biology: In microscopy and image analysis, layer thickness can refer to the measurement of the depth or height of a cellular layer. Determining the thickness of specific layers within a cell structure often requires sophisticated image analysis techniques. https://forum.image.sc/t/analyzing-cell-layer-thickness/8045
-
Ophthalmology: The term may also refer to the thickness of the lipid layer in the tear film of the eye, which is relevant in diagnosing and understanding dry eye conditions. https://pubmed.ncbi.nlm.nih.gov/19574906/
