What filament densities does this use?

PLA: 1.24 g/cm³, PETG: 1.27 g/cm³, ABS: 1.04 g/cm³, TPU: 1.21 g/cm³. These are standard values; actual density varies slightly by brand.

How is machine depreciation calculated?

Printer cost divided by expected lifetime in hours gives cost per hour. This is multiplied by print time to get the depreciation portion of your total cost.

What does the failure rate field do?

It divides total cost by (1 − failure rate). If 10% of prints fail, each successful print must cover that lost material and time, so the expected cost per good print rises.

How is the selling price calculated?

Selling price = expected cost per successful print × (1 + markup / 100). A 30% markup on a $2.00 cost yields a $2.60 selling price.

Can I enter filament in cm³ instead of grams?

Yes. Toggle the unit selector next to the filament field. The tool converts cm³ to grams using the selected filament density.

What is a realistic printer wattage to enter?

Entry-level FDM printers (Ender 3, Bambu A1 Mini) draw roughly 80–180 W during a print. Check your printer's spec sheet for the rated power draw.
