Filament estimate (STL mode) — Derived from STL solid volume using simplified wall, top/bottom, and infill geometry. Accuracy is typically ±10–15% of slicer output. Supports, brim, skirt, and non-standard infill patterns are not modelled.
Print time estimate — Derived from estimated path lengths and print speed. Perimeters modelled at 75% of set speed; travel overhead ~15%. Accuracy is typically ±20–25%. Acceleration limits, pressure advance, and cooling pauses are not modelled. Use your average speed, not peak speed.
Electricity cost — Print hours × (watts ÷ 1000) × rate per kWh. Actual draw varies by phase; 150 W is a reasonable average for a standard FDM printer.
