Kerf in 3D Printing Kerf refers to the material lost during cutting, milling, or laser processes, but in 3D printing, it applies to the slight discrepancies between the intended and actual printed dimensions due to nozzle width or material shrinkage. Proper kerf compensation ensures parts fit together correctly, especially for interlocking components or mechanical assemblies. Adjusting slicer settings, such as extrusion width or dimensional compensation, helps correct kerf issues. Different materials exhibit varying degrees of kerf due to thermal expansion and contraction. Understanding kerf is crucial when designing precise models for applications like snap-fit parts, hinges, or modular assembly systems. |
