3D Print Cost & Time Calculator

The filament type. It sets the density used to turn volume into grams and the typical print throughput — TPU prints far slower than PLA, for example.

What a kilogram of this filament costs you, in your own currency; every cost in the result inherits that currency.

Choose which number you can read off. The sliced weight in grams is the accurate route; the model volume plus an infill guess is a rougher first estimate.

The solid volume of the model in cm³, as CAD or the slicer reports it; the infill percentage below scales it down to the material actually deposited.

The material weight the slicer predicts for the finished print, in grams. It is used as-is, which makes this the most accurate input.

How solid the interior is printed. 20% is a common default; the estimate assumes about a quarter of the volume is solid shell regardless of the infill setting.

Extra material beyond the model itself: purge lines, brims, rafts and supports. 10% is typical for simple parts; support-heavy prints can need far more.

The print-quality profile, which drives the time estimate: draft layers print about 1.6× faster than standard, fine quality about 0.6× as fast.

The printer’s average electrical draw while printing, used for the electricity cost. Averages run well below the rated peak once the bed is warm.

Your electricity tariff per kilowatt-hour, in the same currency as the filament price.

How many prints fail in the long run. Their wasted material and time are spread over the good ones: at 5%, each successful print carries about 5% extra cost.

Profit margin added on top of the total cost to suggest a selling price: 0 reports the bare cost, 100 doubles it.
