3D Printing Cost Calculator: The True Cost Per Print
Most makers underprice their work because they use a basic filament cost calculator and stop there. To run a profitable farm, you must account for Electricity and Machine Depreciation too.
Hidden Costs: Power & Wear
An Ender 3 or Bambu Labs printer runs for hours. We calculate the Watts/Hour against your local kWh rate (average $0.14/kWh). We also amortize your machine's lifespan (e.g., 2,500 print hours) to cover the inevitable replacement of nozzles, fans, and belts.
The "Failure Rate" Buffer
Prints fail. It's a fact of life. Whether it's a bed adhesion issue or a spaghetti monster, you need a buffer. Our tool adds a default 10% Failure Rate to your cost, acting as "self-insurance" so your successful sales pay for the failed ones.
Pro Tip: Reduce your failure rate by keeping your filament dry. Moisture is the #1 enemy of print quality. A simple filament dryer or dry box can save you hundreds of dollars in failed prints over a year.

Printing ROI FAQs
Does infill percentage affect price?▼
Yes, significantly. Higher infill uses more material and triples print time (increasing electricity cost). Only use high infill (>20%) for functional mechanical parts that need strength.
How do I calculate grams without a scale?▼
Your Slicer software (Cura, PrusaSlicer, Orca) will give you an estimated weight in grams after slicing. Use that number in this calculator for a pre-print estimate.
Is this the same as a filament cost calculator?▼
A basic filament cost calculator only accounts for material — spool cost divided by grams used. This tool goes further, adding electricity usage and machine depreciation on top of filament cost, so you get your true total cost per print instead of just the material price.
