Calculators

These calculators do the arithmetic around a print: what it costs, what to charge, how much filament it takes, whether it fits, and how long a run of plates will take. They do not replace your slicer. Wherever a calculator needs a weight, a volume or a time, take it from the slicer after slicing.

Nothing you type is saved. Length fields follow the Inch switch; every other field shows its unit next to the label. Money fields only change the symbol shown; nothing is converted between currencies.

Filament cost

The material cost of one FDM print, from the spool price and the filament weight your slicer reports.

Print cost and price

Material plus power, your time, finishing and an allowance for failed prints, and the price that gives the margin or markup you choose.

Resin cost

The material cost of one resin print, from the bottle price and the volume your slicer reports with supports. For how resin and FDM differ, see FDM vs Resin.

Filament length and weight

Grams to meters and back, for checking whether what is left on a spool will finish a print.

Layer count

How many layers a part takes at a given layer height. Polymaker notes that a 0.1 mm layer height triples print time compared with 0.3 mm at the same nozzle and speeds Rule of thumb. For choosing a layer height, see Choosing a Layer Height.

Job time

The slicer's estimate for one plate, multiplied out over a run of plates with the time to change each one.

Volumetric flow

How many cubic millimeters of plastic per second a line width, layer height and speed ask the hotend to melt.

Model scale

Scale a model by a percentage, or to a size you need on one axis, and see every new dimension.

Dimensional accuracy

Compare a measured print with its designed size and get a first corrected size for the model.

Build volume fit

Check whether a model fits your printer, in every way its sides can line up with the printer's axes.
