Creality Ender-3 V3 KE running cost

The Creality Ender-3 V3 KE has an example price of $199.00 (entered by us, verify with the vendor) and draws roughly 100 W while printing. Amortized over an assumed 4,000-hour service life, that is $0.05 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 $0.07 per hour combined.

Example price (verify with vendor): $199.00
Average power draw: 100 W
Build volume: 220 x 220 x 240 mm
Machine allocation (4,000 hr life): $0.05/hr
Energy at 16.32¢/kWh: $0.02/hr
Combined machine + energy: $0.07/hr

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.
