Creality SPARKX i8 vs Elegoo Centauri Carbon 2: print cost head-to-head

Specs side by side

Sample calculation

Same input on both columns: 50 g PLA part, 6 h print time, 8% failure rate. Energy cost held at $0.18/kWh, amortization uses each printer's regional price — so both the machine and its price drive the numbers.

Verdict by dimension

• Cheaper to buy

  Tie

  Both printers land within the noise threshold for this dimension.

• Cheaper to run

  Creality SPARKX i8

  Creality SPARKX i8 draws 200 W on average vs 210 W for the Elegoo Centauri Carbon 2 — lower power means a smaller energy line in every print.

• Longer useful life

  Elegoo Centauri Carbon 2

  Elegoo Centauri Carbon 2 is rated at 22,000 h vs 20,000 h for the Creality SPARKX i8, so amortization spreads over more printing hours.

• Larger build volume

  Tie

  Both printers land within the noise threshold for this dimension.

• More recent release

  Tie

  Both printers land within the noise threshold for this dimension.

Both target Enthusiasts buyers, so the decision usually comes down to brand ecosystem and after-sale service.

Over a 5-year horizon, the Elegoo Centauri Carbon 2 amortizes 1.1× more print-hours than the Creality SPARKX i8.
