In this study, the impact of CO₂ laser engraving and scanning on various types of wood before and after thermal treatment is investigated. An infrared CO₂ laser with a wavelength of 10640 nm is used in the study for engraving various wood samples before and after thermal treatment at a specific processing temperature of 214 °C. All samples had similar moisture content – approximately 8%. The engraving depth and width were measured for each wood sample. The findings reveal that thermal pre-treatment exert a discernible influence on the efficacy of laser engraving, and the engraving depth is notably influenced by the particular wood species involved. Consequently, the study offers a platform for assessing the optimization of laser engraving parameters applicable to different wood types and thermally modified wood, thereby facilitating the enhancement of product quality through judicious parameter selection.
