Material Compatibility (The Most Important Factor)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is usually the deciding factor for buyers. Because different materials absorb light at different wavelengths, these machines are rarely interchangeable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>CO2 Lasers (Non-Metals)<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Best for:<\/strong>&nbsp;Wood, Paper, Leather, Acrylic, Glass, Fabrics, Rubber, Cork, Stone.<\/li>\n\n\n\n<li><strong>Metal limitations:<\/strong>&nbsp;Cannot mark bare metals directly. The beam usually bounces off metal surfaces unless the metal is painted, anodized, or coated with a marking spray (like Cermark).<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Fiber Lasers (Metals)<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Best for:<\/strong>&nbsp;Stainless Steel, Aluminum, Brass, Copper, Titanium, Gold, Silver, Carbides.<\/li>\n\n\n\n<li><strong>Plastics:<\/strong>&nbsp;Works very well on engineered plastics (ABS, Nylon, PES) often creating a high-contrast color change.<\/li>\n\n\n\n<li><strong>Non-Metal limitations:<\/strong>&nbsp;The beam will pass right through transparent materials like glass or acrylic without marking them, and it can burn or char wood dangerously rather than engraving it cleanly.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. Lifespan and Maintenance<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fiber Laser:<\/strong>&nbsp;Often called &#8220;fit and forget.&#8221; The laser source is solid-state, meaning there are no loose parts inside the source to break. A fiber unit can easily run for 8-10 years (100,000 hours) with minimal maintenance.<\/li>\n\n\n\n<li><strong>CO2 Laser:<\/strong>&nbsp;The laser tubes are consumables. A glass DC tube might last 1,000\u20132,000 hours, while a higher-end RF metal tube might last 20,000+ hours. They also require a system of mirrors that must be kept clean and perfectly aligned to function correctly.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3.
