About PrintBench
Simple, accurate, free tools for the everyday math of 3D printing.
⚙️ AI disclosure: PrintBench's tools, copy, and
reference tables are built and maintained with AI assistance. We show the formula behind
every calculator so you can check the math yourself, and we label typical figures as ranges
rather than presenting them as specs for any specific machine.
Why trust the numbers?
Because you don't have to trust them — every calculator shows its formula in plain text, and the math is standard arithmetic (cost per gram, kilowatt-hours, and so on). If a result ever looks off for your setup, check it against the formula and your own measurements.
How it stays free
PrintBench is free to use. In future, some pages may include links to products (such as filament or accessories); where they do, those links will be clearly disclosed. Affiliate links, if used, never change the price you pay.
Found an error or want a tool?
The calculator library grows continuously. If a figure looks wrong or there's a calculation you wish existed, that feedback shapes what gets built next.
