The term &#8220;CO2 Laser&#8221; covers a wide range of machines, but for\u00a0marking\u00a0applications, the most critical choice is between the\u00a0Laser Source Type\u00a0(Glass vs. Metal) and the\u00a0Machine Structure\u00a0(Galvo vs. Gantry).<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here is a step-by-step guide to making the right choice.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Choose the Machine Structure: Galvo vs. Gantry<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is the first and most important decision. It depends on whether you need&nbsp;<strong>speed<\/strong>&nbsp;(marking) or&nbsp;<strong>size\/cutting<\/strong>&nbsp;capability.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Feature<\/th><th><strong>Galvo CO2 (Galvanometer)<\/strong><\/th><th><strong>Gantry CO2 (Flatbed\/Plotter)<\/strong><\/th><\/tr><tr><td><strong>Best For<\/strong><\/td><td><strong>High-speed marking<\/strong>, coding, logos, serial numbers.<\/td><td><strong>Cutting<\/strong>&nbsp;shapes, processing large sheets, engraving photos.<\/td><\/tr><tr><td><strong>Speed<\/strong><\/td><td>Extremely fast (up to 7000mm\/s).<\/td><td>Slower (mechanical movement of the head).<\/td><\/tr><tr><td><strong>Working Area<\/strong><\/td><td>Fixed, usually small (e.g., 100x100mm to 300x300mm).<\/td><td>Large and scalable (e.g., 600x400mm, 1300x900mm).<\/td><\/tr><tr><td><strong>Typical Use<\/strong><\/td><td>Marking expiration dates, leather patches, denim jeans, greeting cards.<\/td><td>Cutting acrylic letters, architectural models, wood crafts.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Verdict:<\/strong>&nbsp;If your goal is &#8220;Marking&#8221; (adding text\/logos quickly), choose a&nbsp;<strong>Galvo<\/strong>&nbsp;machine. If you need to cut out shapes, choose a&nbsp;<strong>Gantry<\/strong>&nbsp;machine.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. Choose the Laser Source: RF Metal Tube vs. DC Glass Tube<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This determines the quality of the mark, the machine&#8217;s lifespan, and the price.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>A. RF Metal Tube (Radio Frequency)<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pros:<\/strong>&nbsp;Produces a very fine, precise beam (0.07mm spot size). Very long lifespan (~20,000\u201340,000 hours). Air-cooled (no water chiller needed for lower powers). fast switching speed (good for detailed images).<\/li>\n\n\n\n<li><strong>Cons:<\/strong>&nbsp;Expensive (often 5x the price of a glass tube).<\/li>\n\n\n\n<li><strong>Best For:<\/strong>&nbsp;High-precision marking, barcodes, detailed graphics, industrial 24\/7 production.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>B. DC Glass Tube<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pros:<\/strong>&nbsp;Very affordable. Excellent for&nbsp;<strong>cutting<\/strong>&nbsp;or deep engraving where precision is less critical.<\/li>\n\n\n\n<li><strong>Cons:<\/strong>&nbsp;Short lifespan (~2,000 hours). Fragile. Requires a water chiller. The beam is &#8220;thicker,&#8221; meaning it cannot do microscopic detail well.<\/li>\n\n\n\n<li><strong>Best For:<\/strong>&nbsp;Cutting applications, hobbyists, budget-conscious buyers.<\/li>\n\n\n\n<li><strong>Verdict:<\/strong>&nbsp;For professional&nbsp;<em>marking<\/em>, the&nbsp;<strong>RF Metal Tube<\/strong>&nbsp;is the standard. For&nbsp;<em>cutting<\/em>&nbsp;or low-budget engraving,&nbsp;<strong>Glass Tube<\/strong>&nbsp;is sufficient.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. Determine the Power (Wattage)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Higher power is not always better. It depends on the material depth.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>30 Watts:<\/strong>&nbsp;The standard for marking&nbsp;<strong>paper, cardboard, leather, and wood<\/strong>. It can mark quickly but is weak for cutting.<\/li>\n\n\n\n<li><strong>60 Watts:<\/strong>&nbsp;Good versatility. Can mark deeper and cut thin materials (e.g., 3mm acrylic\/wood).<\/li>\n\n\n\n<li><strong>100 Watts+:<\/strong>&nbsp;Primarily for high-speed&nbsp;<strong>cutting<\/strong>&nbsp;or marking denim (fabric burning). Note that high power can sometimes be too aggressive for delicate materials like paper, causing burning instead of marking.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. Select the Lens (Working Area)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In Galvo machines, the lens determines your working area.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Rule of Thumb:<\/strong>&nbsp;A&nbsp;<strong>smaller<\/strong>&nbsp;working area =&nbsp;<strong>Stronger<\/strong>&nbsp;marking power and&nbsp;<strong>finer<\/strong>&nbsp;detail.<\/li>\n\n\n\n<li><strong>Example:<\/strong>&nbsp;A 30W laser with a 100x100mm lens can mark deep into wood. The same 30W laser with a 300x300mm lens might barely leave a mark because the energy is spread out over a larger spot size.<\/li>\n\n\n\n<li><strong>Recommendation:<\/strong>&nbsp;Buy the lens that fits your&nbsp;<em>largest common product<\/em>, but don&#8217;t go bigger than necessary. A&nbsp;<strong>175x175mm<\/strong>&nbsp;lens is a common &#8220;sweet spot.&#8221;<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">5.
