7W+ Laser Head – Precision Engraving Champion

• Best For: Photo engraving, vector engraving, fine detail work
• Power Output: ~6–7W typical
• Focus: Fine spot (~0.0035–0.006 inches) and adjustable
• Key Benefit: Single ultra-fine beam ideal for high-resolution images and intricate designs
• Use Case: If you’re creating photo-realistic wood engravings or engraving anodized aluminum, this is your go-to.

14W Dual PRO SI – Faster Engraving with Precision

• Best For: Versatile engraving with limited cutting (thin or soft materials)
• Power Output: ~12–14W typical
• Focus: Fixed focus with magnetic shroud
• Key Benefit: Two 7W beams combined for higher density and speed
• Use Case: A great step up for users who want to do faster engraving and experiment with thin material cutting like balsa or cardstock.

24W Quad PRO – Versatile Mid-Range Workhorse

• Best For: Engraving and cutting wood, leather, acrylic
• Power Output: ~22–24W typical
• Focus: Fixed ¼” below the shroud
• Key Benefit: Four 7W beams combined for consistent, powerful cutting and engraving
• Use Case: Perfect balance between speed, performance, and affordability for serious makers and small business use.

44W Octo PRO – High-Power Production Tool

• Best For: Faster cutting and production-level engraving
• Power Output: ~44W
• Focus: Optimized beam for speed, with air assist and magnetic shroud
• Key Benefit: Eight 7W beams combined for rapid job turnaround and deep cuts
• Use Case: Ideal for cutting thicker woods, or speeding up large projects. Great for batch production.

64W 3-in-1 PRO – Ultimate Power and Flexibility

• Best For: All-in-one engraving, photo work, and high-speed cutting
• Power Output: Configurable 24W, 44W, or full 64W
• Modes: Switch between cutting and photo engraving without changing hardware
• Key Benefit: Combines raw power with the precision of a dedicated engraving mode; includes crosshair alignment laser
• Use Case: For users who want it all — high-end cutting and top-tier photo engraving in one device. Perfect for professionals or advanced hobbyists.

Speed Comparison (for vector engraving on birch plywood)

Birch plywood is one of the most popular materials for laser engraving due to its smooth grain, light color, and consistent performance. It offers excellent contrast when engraved, especially with blue diode lasers. Whether you’re burning in logos, names, or intricate artwork, birch delivers sharp detail and clean edges. Lighter laser head for CNC like the 7W+ produce beautifully dark, precise engravings at slower speeds, while higher-powered models like the 24W, 44W, or 64W can dramatically increase throughput. For example, you can expect deep, dark lines at around 40–60 in/min with the 7W+, or speeds of 600–1000 in/min with the 64W—assuming your CNC can keep up. It’s the go-to material for everything from personalized signs to product tags.

Which One Should You Choose?

• New to laser engraving? Start with the 7W+ kit—high definition, safe, and upgrade-ready.
• Want engraving + light cutting? Step up to the 14W Dual PRO SI.
• Doing leather, acrylic, thicker wood? The 24W Quad PRO delivers power at great value.
• High-volume or thick material cutting? The 44W Octo PRO accelerates your workflow.
• Need the ultimate flexibility? The 64W 3‑in‑1 PRO does it all—cutting, engraving, and photo work.

Each laser for CNC is fully compatible with our Safety Interface System, ensuring reliable performance and adherence to Class 4 safety standards. Choosing the right model depends on your speed needs, materials, and budget. Still not sure which one is for you? Feel free to reach out — we love helping makers make the best choice!
