Filament and print cost

Spool remaining: weigh the spool and subtract the empty-spool weight (choose a type or enter your brand’s exact figure).

Length ↔ weight: grams = π × (d/2)² × length × density. A 1 kg spool of 1.75 mm PLA is about 330 m.

Print cost: material (grams × price per kg) + electricity (average watts × hours × price per kWh) + wear per hour, plus a failure allowance and any extras, split over the copies printed.

Job from G-code: drop in a .gcode file and the tool reads the slicer’s own estimates of time and filament from its comments — Cura (;TIME:, ;Filament used:), PrusaSlicer, SuperSlicer, OrcaSlicer and Bambu Studio (estimated printing time, total estimated time, filament used [g]), and Simplify3D. Without those comments it sums the extrusion and estimates the time from the moves at their feed rates; that ignores acceleration, so it reads short. Then cost a batch: parts per plate and parts needed give the number of plates; each plate adds its heat-up energy and your hands-on time (removing parts, cleaning the bed) at a labour rate. Binary G-code (.bgcode) is compressed — export plain G-code to read it here. The file never leaves your browser.

For a customer quote with several lines, saved printer and material profiles, markup, minimum charge, tax and a printable quote, use the 3D print cost quoter. It reads the G-code with this tool’s reader.

Materials: typical nozzle and bed temperatures, enclosure needs, drying, heat resistance, and densities — starting points; your filament’s label wins.
