3D Print Filament Calculator

Work out the mass and cost of 3D-printing filament for a print. Enter filament length (or object mass), the filament diameter and material density, and the price per spool or per kilogram; the tool gives the mass or length, the filament volume, and the material cost. Useful for costing prints and judging how much of a spool a job will use. Mass assumes solid filament of the chosen density — it does not account for infill or support material.
