3D Printing Cost Calculator
Work out what a print really costs you. Load an STL or type the grams from your slicer to get filament, power and failure costs, plus a price to sell it at.
Quick start
- Load an STL, OBJ, 3MF or PLY model, or choose “Enter weight” and type the grams your slicer reports.
- Adjust infill, print time, filament price and your electricity rate.
- Read the total, then add a markup to get a selling price.
The formula
Material = grams × price per kilo. Power = watts × hours × price per kWh. A failure rate covers prints that go wrong, and optional labor and markup turn the cost into a price.
Weight from a file vs. from a slicer
Weight estimated from a 3D file uses typical walls and your infill. The number your slicer shows after slicing is always the most precise, so use it when you have it.
Questions & answers
Do you keep a copy of my model?
Never. The file is opened by your own browser and is not sent to any server, which makes the tool safe for commissioned, paid or unreleased models.
Does it cost anything?
No. There is no account to create, no watermark and no limit on how many files you open.
What does an average 3D print cost?
Small and medium prints usually cost well under two dollars. A 50 g PLA figure is roughly a dollar of filament plus a few cents of electricity.
How many watts does a 3D printer draw?
Most FDM printers average 80 to 200 W while printing, with a short peak while the bed heats up. Type your own value for a closer result.
How should I price prints I sell?
Take the total cost, add your time for slicing, support removal and sanding as labor, then add a profit margin. A markup of 100% or more is common.
