8 3D printing calculators.
No sign-up. No tracking. No ads.
Real cost of a print: filament used, electricity and a failure allowance.
Convert filament grams to metres and back, per material and diameter.
Weigh a spool to see the grams and metres left, and if your print fits.
Cost of an SLA/MSLA print from ml used, bottle price and waste allowance.
Corrected extruder steps/mm from a measured 100 mm extrusion test.
Corrected slicer flow / extrusion multiplier from a measured single wall.
Scale factor and compensated size so a print shrinks to the target dimension.
mm³/s from layer height x line width x speed, vs your hotend melt limit.
A set of 3D printing calculators for FDM and resin printing: what a print really costs (filament plus electricity), filament length to weight, how much is left on a part-used spool, resin cost per print, e-steps and flow-rate calibration, shrinkage compensation and the volumetric-flow speed limit of your hotend. All pure maths, running in your browser.
They use the standard closed-form formulas: cylinder volume times density for filament weight (1 kg of 1.75 mm PLA is about 335 m), the classic e-steps and flow corrections, target ÷ (1 − shrinkage) for compensation, and layer height × line width × speed for volumetric flow. Material densities and hotend limits are typical values; enter your own for precision work.
They complement them. The slicer tells you grams, millilitres and time; these calculators turn that into money, tell you if the spool has enough left, and correct the numbers your slicer assumes (flow, shrinkage, speed limits).
No. Every calculator runs entirely in your browser with no download, sign-up, or data leaving your device.
