Bambu Lab vs Prusa vs Creality: Total Cost of Ownership (2026)

"Which printer should I buy?" is the wrong question. "Which printer costs less to run for three years for my workload?" is the right one. Here's a real TCO comparison.

The contenders

• Bambu Lab P1S Combo — $850
• Prusa MK4S Kit — $900
• Creality K1 Max — $750

All three are mid-tier FDM machines that small print shops commonly choose. Numbers below assume 1,500 hours/year of printing for 3 years (~4,500 hours total).

Year 1 purchase

Cost	Bambu P1S	Prusa MK4S	Creality K1 Max
Printer	$850	$900	$750
AMS / MMU / no	included	+$300 MMU3	n/a
First spare set	$50	$40	$60
Total Y1 capital	$900	$1,240	$810

Consumables over 3 years

Cost	Bambu	Prusa	Creality
Nozzles (×6–8)	$40	$30	$50
Hotend / heater swap	$90	$40	$110
Build plate replacement (×1–2)	$50	$40	$40
AMS/MMU service	$80	$120	n/a
Belts / fans	$25	$30	$50
3-yr consumables	$285	$260	$250

Reliability & downtime

This is where the spreadsheet starts lying.

• Bambu: ~5% of weeks have a calibration or AMS issue. ~2 hr/week troubleshooting at the median. Annual support cost in time: ~50 hr.
• Prusa: ~2% of weeks. Boring. Issues are rare and fixable from documentation. ~20 hr/year.
• Creality K1: ~12% of weeks. Slicer quirks, screen failures, klipper updates. ~80 hr/year.

At $25/hr opportunity cost:

Machine	Annual downtime cost	3-year
Prusa	$500	$1,500
Bambu	$1,250	$3,750
Creality	$2,000	$6,000

Resale value at year 3

Machine	Resale	Net depreciation
Bambu P1S	$400	$500
Prusa MK4S	$500	$740
Creality K1 Max	$250	$560

Prusa holds value because Prusa machines stay supported. Creality machines age out of the community fast.

All-in 3-year cost

Machine	Capital	Consumables	Downtime	Net of resale	TCO
Prusa MK4S	$1,240	$260	$1,500	-$500	$2,500
Bambu P1S	$900	$285	$3,750	-$400	$4,535
Creality K1 Max	$810	$250	$6,000	-$250	$6,810

Prusa wins on TCO despite the highest sticker price, because reliability is the dominant cost.

When the math flips

This analysis flips if:

• You print less than 500 hours/year — capital cost dominates; the Creality wins.
• You print rainbows/multi-color constantly — Bambu's AMS reliability beats Prusa MMU3, and the labor delta wipes out everything.
• You run unattended overnight — Bambu's lidar and crash detection are objectively better; the downtime cost gap shrinks.

What to actually buy

• Print farm running 8+ hours daily: Prusa MK4S. Boring is profitable.
• Multi-color hobbyist/Etsy seller doing 30 prints/month: Bambu P1S Combo.
• Budget-constrained, willing to tinker, single-color: Creality K1 Max.

Capital cost is the smallest part of the equation. Reliability is the largest. Quote that to anyone who says "I'll just buy the cheap one to start."
