About PrintGrams

PrintGrams started with a simple annoyance: every time I wanted to know what a print cost, how much filament was left, or whether 0.15 mm was a sensible layer height, I ended up on a different blog with a different half-working calculator and no way to check its maths.

So this site does three things differently. Every calculator shows the formula it uses. Every number it relies on — filament density, printer wattage, marketplace fees — is listed with its source on the filament and printer pages. And everything runs in your browser: files you drop into the STL analyzer never leave your computer.

How it is funded

The site is free and will stay free. It shows a small number of ads, which pay for the domain, hosting and the time spent keeping the data current. We do not sell data and we do not take payment to change a number.

Corrections

If a figure is wrong, tell us with a source and it will be fixed. Measured printer wattages are especially welcome: plug-meter readings beat estimates every time.
