Values assume a filament dryer or oven. Always dry below the material's softening point so the spool keeps its shape.
Tap any cell to see how the row material bonds to the column material when printed together or fused in a multi-part assembly.
The size you want the finished, cooled part to measure. The tool scales the model up so it shrinks down to this.
Drying values are conservative starting points for a filament dryer or oven and are kept below each material's softening point. Check your spool maker's datasheet — fillers (CF/GF) and brand differences shift the ideal temperature. Never dry PLA above ~50 °C or the spool can deform.
Adhesion and shrinkage figures are typical-case averages across common desktop filaments. Inter-material bonding depends on print temperature, layer overlap, and surface prep; shrinkage depends on geometry, part size, cooling, and moisture. For anything dimensionally critical, calibrate with a test print. Cross-check fits on the Tolerance & Fit Calculator and material limits in the Filament Material Guide.
