3D Printing & CAD Calculator
Standardized mechanics and slicing calculations for filament volumes, layer speeds, material infill, bed boundaries, and precision ISO tolerancing fits.
1. Nominal Size & Fit Selector
2. Tolerances & Slicer Compensation Report
Standard FDM 3D printers expand printed holes inward by about 0.1 to 0.15mm due to plastic shrinkage and extrusion overhangs. To achieve true ISO sliding fits, apply an XY Size Compensation / Horizontal Expansion of -0.10mm inside your slicer settings!
