What can a CO₂ laser like the Glowforge Spark cut that a diode laser cannot?
CO₂ lasers can cut and engrave clear acrylic, glass (with care), fabric, and thicker wood more cleanly than diode lasers, because the CO₂ wavelength is absorbed by materials that are transparent to diode light. This makes the Glowforge Spark more versatile for craft and production use.
