| Wattage (avg printing) | 165W | 120W |
| Electricity cost/hr | £0.061/hr | £0.044/hr |
| Print speed (avg) | 250 mm/s | 150 mm/s |
| Depreciation/hr (3yr) | £0.034/hr | £0.023/hr |
| Total running cost/hr | ~£0.095/hr | ~£0.067/hr |
| Monthly cost (8hr/day) | ~£22.80/mo | ~£16.10/mo |
| Failure rate (typical) | ~3–5% | ~8–12% |
Electricity at £0.37/kWh (UK average 2026). US figures: multiply by 0.65. Use the electricity calculator for your exact rate.
Why running cost matters more than purchase price
A cheap printer that fails 12% of the time wastes filament and time. A £100 difference in purchase price disappears in 3 months of printing. The Ender 3 V3 SE is cheaper to buy and run per hour — but the Bambu A1 Mini's lower failure rate and higher throughput change the maths for anyone selling prints.
Electricity: the daily cost you never think about
At 8hr/day, the A1 Mini costs ~£5.40/mo more in electricity alone than the Ender 3 V3 SE. That's £65/year — roughly the price difference between the two machines. If you print infrequently, the Ender wins on electricity. If you print daily, the gap narrows when you factor in throughput.
Depreciation: spreading the purchase price
Calculate depreciation as price ÷ hours of life. At 5,000hr lifespan: Ender = £0.040/hr, A1 Mini = £0.060/hr. Over 3 years at 8hr/day = ~8,760 hours. The A1 Mini's higher purchase price means higher depreciation per hour — but its speed means you complete more jobs per hour, so depreciation per finished print can be similar or lower.
Speed changes the maths
Because the A1 Mini prints at 250mm/s vs 150mm/s, it finishes a job ~40% faster. A job that takes 4hr on the Ender takes 2.5hr on the A1 Mini — meaning less total electricity per completed print. At 40mm³/s effective flow vs 24mm³/s, a 100g PLA print takes significantly less time and electricity on the Bambu.
Which is cheaper if you're selling prints?
For Etsy sellers, throughput = revenue. At 8hr/day the A1 Mini can complete ~3.2 jobs vs ~2 jobs for the Ender (assuming average 2.5hr print). Revenue difference compounds fast. The A1 Mini pays for itself within 4–6 months through higher throughput if you're selling.
The Ender 3 V3 SE is cheaper to buy and run per hour. The A1 Mini pays for itself within 4–6 months through higher throughput if you're selling. If you're a hobbyist printing occasionally, get the Ender.
