Bambu Lab A1 running cost
The Bambu Lab A1 has an example price of $399.00 (entered by us, verify with the vendor) and draws roughly 110 W while printing. Amortized over an assumed 4,000-hour service life, that is $0.10 of machine allocation per hour; at the 2024 U.S. average electricity price of 16.32¢/kWh, energy adds another $0.02 per hour, for about $0.12 per hour combined.

How this is calculated
Machine allocation = (purchase price − expected resale value) ÷ service life hours; this page assumes zero resale and a 4,000-hour service life. Energy = watts ÷ 1,000 × price per kWh. Both are cost-model assumptions, not a manufacturer specification; open the calculator to use your own service life, resale value, and electricity rate.
