Bambu Lab A1 vs Creality SPARKX i8: 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.
