3D printing calculators

Every calculator updates as you type, works offline once loaded, and keeps your numbers in the link so you can share them.

Cost

Work out what a 3D print really costs: filament, electricity, machine wear and failures, plus a suggested sell price. Free and instant.

Estimate resin volume, weight and cost per print including supports, and how many prints you get from a 1 L bottle.

Get a rough print time from part volume, layer height, line width and speed, and check you are within your hotend flow limit.

Calibrate your extruder: enter your marks and get the corrected E-steps, the M92 command, and the Klipper rotation_distance.

Measure a single-wall test cube and get the corrected flow rate or extrusion multiplier for your slicer.

Find the dimension to model so the printed part comes out right after shrinkage, plus hole clearance for press, slip and loose fits.

Convert filament meters to grams and grams to meters for PLA, PETG, ABS, TPU, nylon and more, at 1.75 or 2.85 mm.

Weigh your spool and find out how many grams and meters of filament are left, and whether it is enough for your next print.
