Bambu Lab vs Prusa vs Creality: Which 3D Printer Is Cheapest to Run? (2026)
The sticker price is only part of the story. A £1,149 Bambu X1 Carbon might cost less per hour to run than a £229 Ender-3 if its lifespan is long enough. This guide works out the true running cost per hour for the most popular printers — electricity, depreciation, and maintenance — using real spec data. See our electricity cost post for the formula.
Running Cost Per Hour: Top Picks
| Printer | Price | Total cost/hr (UK) | Total cost/hr (US) |
|---|---|---|---|
| Prusa Mini+ | £399 | £0.131 | $0.104 |
| Ender-3 V3 | £229 | £0.174 | $0.130 |
| Bambu A1 Mini | £299 | £0.188 | $0.151 |
| Prusa MK4 | £799 | £0.215 | $0.157 |
| Bambu P1S | £699 | £0.299 | $0.220 |
| Creality K1 | £349 | £0.243 | $0.161 |
| Bambu X1 Carbon | £1,149 | £0.381 | $0.269 |
Surprisingly, the cheapest printer to buy is not always cheapest to run. The Ender-3 V3 (£229) and Bambu A1 Mini (£299) are very close in cost-per-hour despite a £70 price difference.
How We Calculate Running Cost
Running cost per hour = Depreciation/hr + Maintenance/hr + Electricity/hr
- Depreciation/hr = Printer purchase price ÷ Rated lifespan (hours)
- Maintenance/hr = Annual maintenance cost ÷ 1,500 (estimated annual print hours)
- Electricity/hr = (Print wattage ÷ 1,000) × Electricity rate (£/kWh)
Worked example for Bambu A1 Mini (UK): Depr: £299 ÷ 3,000h = £0.100/hr. Maint: £40 ÷ 1,500h = £0.027/hr. Elec: (180W ÷ 1,000) × £0.34 = £0.061/hr. Total: £0.188/hr.

Brand-by-Brand Analysis
Bambu Lab (A1 Mini, P1S, X1 Carbon)
A1 Mini: best value Bambu — low entry price, decent lifespan, low wattage. Running cost comparable to Ender-3 at nearly the same price. P1S: enclosed CoreXY, much higher wattage (350W), shorter lifespan per price — cost/hr is noticeably higher. Justified by speed and reliability for high-volume farm use. X1 Carbon: highest absolute cost/hr due to price + wattage. Justified only if print speed means significantly more output per hour.
Prusa (MK4, Mini+)
MK4: 8,000h rated lifespan is exceptional — spreads the £799 purchase price over 2.5× as many hours as budget machines. Total cost/hr competitive with machines costing half the price. Mini+: lowest wattage (120W) in the comparison. Excellent cost/hr. Limitation is build volume (180×180×180mm) — not suitable for large parts.
Creality (Ender-3 V3, K1)
Ender-3 V3: cheapest upfront, reasonable lifespan, moderate wattage. Total cost/hr is actually higher than Bambu A1 Mini once electricity is factored in due to higher wattage at similar lifespan. K1: high wattage (350W) cuts into running cost efficiency. Better justified by print speed (600mm/s rated) if you're printing at volume.
The Speed Factor — Cost Per Print vs Cost Per Hour
A faster printer printing the same item costs less total even if its hourly rate is higher, because it finishes in fewer hours. Example — 80g PLA phone stand at 100% quality:
| Printer | Print time | Running cost/hr | Total running cost for print |
|---|---|---|---|
| Ender-3 V3 (60mm/s) | 3.5h | £0.174 | £0.61 |
| Bambu A1 Mini (200mm/s) | 1.5h | £0.188 | £0.28 |
| Bambu P1S (350mm/s) | 0.8h | £0.299 | £0.24 |
Fast printers often have a lower total cost per print, not just per hour. This is why print farms increasingly standardise on fast machines despite higher sticker prices. See the print farm guide.
Which Printer Should You Choose?
- Hobbyist, budget-conscious: Ender-3 V3 (£229) or Bambu A1 Mini (£299) — similar running cost, Bambu is faster and easier to use
- Serious Etsy seller, 1–2 printers: Bambu A1 Mini or Prusa MK4 — reliability over speed
- Print farm (5+ printers): Bambu A1 Mini fleet — low cost per machine, fast, parts available, farm-mode in Bambu Studio

- Budget, already have one: Second Ender-3 V3 — lowest capital outlay per additional machine
FAQ
Is Bambu Lab cheaper than Prusa to run?
The A1 Mini (£0.188/hr) is slightly more expensive than the Prusa Mini+ (£0.131/hr) but cheaper than the Prusa MK4 (£0.215/hr). Bambu's advantage is speed, which lowers cost-per-print even if cost-per-hour is similar.
What is the cheapest 3D printer to run long-term?
The Prusa Mini+ has the lowest running cost per hour (£0.131/hr UK) due to low wattage and long lifespan. The Ender-3 V3 is cheapest upfront but has moderate running cost.
Does printer wattage really matter for cost?
At 8 hours/day, the difference between a 120W Mini+ and 350W P1S is £0.31/day or ~£113/year. Not decisive alone, but multiplied across a 10-printer farm it's £1,130/year.
How long do 3D printers last?
Budget printers (Ender series): 2,000–4,000 hours. Mid-range (Bambu A1, Prusa): 3,000–6,000 hours. High-end (Prusa MK4, Voron): 6,000–10,000+ hours with proper maintenance.
