    How is it calculated?

    Filament

    Grams × (1 + waste) × price per kg ÷ 1000. If you use several filaments each one is calculated on its own.

    Electricity

    Printer power (kW) × print time (hours) × electricity price. Power is an average that includes heating cycles.

    Shipping & quantity

    Packages = quantity ÷ items per package (rounded up). Shipping is split across the items and no margin is added on it.

    Selling price

    (Cost × (1 + margin) + shipping + fixed fee) ÷ (1 − fee). After the marketplace takes its cut, your target profit stays yours.

    What is Filanomy?

    Filanomy is a free tool that works out the real cost of a 3D print. Upload a sliced .3mf or .gcode, or the model's .stl, and weight and print time fill in automatically. It adds filament, electricity, machine wear, failure margin and, if you sell, shipping and marketplace fees to give you the cost of the print and a selling price. Pick your printer and its power draw and bed size come preset, and you see your part on the bed in 3D.

    To learn the formulas, read how to calculate 3D printing cost; for electricity use see the printer power table; if you sell prints, the pricing guide.

    Frequently asked questions

    Is Filanomy free, and do I need an account?

    It is free and needs no account. Your inputs and saved calculations stay in your own browser only.

    Is my file uploaded to a server?

    No. .3mf, .stl, .gcode and .obj files are read entirely in your browser and never uploaded.

    Which file types can it read?

    .3mf, .stl, .gcode and .obj. Binary G-code (.bgcode) and STEP (.step/.stp) files cannot be read; export them as STL or 3MF.

    How accurate are the weight and time?

    For sliced files (.gcode and Bambu Studio/Orca .3mf) the weight and time are read from what the slicer wrote. For unsliced STL/OBJ files they are estimated from your printer and infill setting and can be off by ±30%.

    What is the difference between Simple and Pro mode?

    Simple mode shows only the real cost for your own prints. Pro mode adds profit margin, shipping, marketplace fees, bulk discounts and PDF quotes.

    What if my printer is not listed?

    Choose "Other / enter manually" and enter the average power draw (watts) and bed size yourself. If a model is missing, let us know on the contact page.
