Heat Resistance Heat resistance refers to the ability of a material to withstand elevated temperatures without undergoing significant degradation or structural changes. In laser engraving, materials with high heat resistance are preferred for applications involving intense laser energy, prolonged exposure to heat, or rapid temperature changes. Heat-resistant materials, such as certain metals, ceramics, and thermoplastics, exhibit minimal softening, melting, or deformation under engraving conditions, allowing for precise and consistent material processing without compromising dimensional accuracy or surface quality. |
