Bambu Lab X1 Carbon: specs, power draw and print cost calculation

The X1 Carbon is Bambu Lab's flagship FDM model, built for engineering plastics and high print repeatability without manual calibration.

Key specs

• Build volume: 256 × 256 × 256 mm.
• Calibration: lidar scanning of the first layer plus automatic vibration compensation (Micro Lidar + accelerometers).
• Max nozzle temperature: up to 300°C — prints PA, PC, and carbon-reinforced composite filaments.
• Power draw: 150–200 W at steady-state printing in a heated room. During the first 5 minutes, while the bed and nozzle heat up together, draw can spike to 400 W. The power supply's rated capacity is 1000 W at 220V (a theoretical ceiling, not operating draw).

Who it suits

• Shops printing engineering plastics (PC, PA, reinforced composites) where an enclosed chamber matters.
• For cost calculation, lidar calibration saves manual first-layer tuning time — worth budgeting as labor savings, not just material.

What to watch for in cost calculation

When converting the rated 150–200 W into hourly print cost, it's convenient to budget an average of ~180 W — the peak 400 W only lasts the first minutes of heat-up and doesn't drive the cost of a multi-hour print.
