The price is primarily driven by the laser source power (measured in Watts) and the brand of the generator (e.g., IPG, Raycus, or Max). For B2B buyers, it is crucial to match the power to your material thickness; for example, a 1000W-3000W machine is ideal for thin to medium sheets, while 6000W+ is required for heavy industrial plates. Additionally, check the cutting bed size (e.g., 3015 or 4020 formats) and the servo motor precision, as high-end brands like Yaskawa or Panasonic will increase the initial cost but ensure long-term accuracy and lower maintenance costs.
