It features an adjustable focal range from 20mm to 50mm, enabling precise engraving with a narrower line width on plywood and similar substrates. The module supports PWM modulation and runs on 12V input with a compact 35x35x99.6mm form factor. It ships with essential cabling and is positioned as an easy upgrade or replacement option for three-axis machines, focusing on stable performance and straightforward installation.
LASER TREE 5W Engraving Module
This 5W laser head offers a 23mm fixed focal length and magnetic eye shield for eye protection. It claims high engraving speed and precision, suitable for cutting thin plywood and engraving various materials with stable blue-laser performance. The unit includes a protective design and straightforward control wiring (XH2.54-3P). At 450nm wavelength and 12V operation, it emphasizes reliability and ease of integration with common CNC platforms and upgrade paths for existing laser modules.
LASER TREE 10W Engraving Module With Air Assist
This 10W module combines a powerful blue diode laser with built-in FAC to shrink the beam at focus and boost cutting depth and engraving speed. It supports air assist to improve material edges and reduce smoke, and it includes a magnetic or air-driven nozzle upgrade to enhance airflow. Documentation highlights compatibility with 3018/3018 Pro CNC platforms and a 45mm focus length ideal for thicker plywood, leather, and some metals when used with appropriate settings.
LASER TREE 10W Module With Air Assist And FAC
Offering 10W optical output and a built-in FAC, this module is designed for precise engraving on stainless steel and other challenging materials. The device ships with a robust air-assist framework and a more refined air nozzle system, aimed at deeper cuts and cleaner edges. It is Class 4 and built for integration with CNC machines that require higher power and improved focal control for faster throughput and deeper penetrations on select substrates.
HUAHENGCHI 12W Laser Engraver Module
This module advertises a real 12W optical output with a built-in FAC and wind-gathering design to protect the lens and maintain precision during long engraving sessions. It supports air assist and an autorun-friendly 50mm focus length, enabling direct engraving on stainless steel and other materials. The unit emphasizes stability, long diode life, and dual-protection features for extended operation in busy workshop environments.
Creality Falcon Pro 10W Laser Engraver
The Creality Falcon Pro 10W Pro Engraver integrates safety features like an emergency stop, a laser protection cover, and a safety lock. The upgraded airflow and a dedicated control box simplify offline operation, with an emphasis on user-friendly one-button workflows. It’s designed to deliver consistent results on wood, paper, acrylic, and some metals, making it a practical option for hobbyists and small workshops seeking reliability and ease of use.
Buying Guide: Key Considerations For CNC Laser Cutter Heads
- Power and materials: Higher wattage enables deeper cuts and faster engraving on harder materials (metal, dense woods, acrylic). Match the wattage to typical projects and required cutting depth.
- Focal length and beam quality: Adjustable vs fixed focus affects versatility with different workpiece thicknesses. FAC and compressed-spot technology improve precision and speed, particularly on stainless steel and dense plastics.
- Air assist and cooling: Air assist reduces scorching and smoky edges, while integrated cooling or fans extend diode life and maintain consistent performance during longer jobs.
- Safety features: Class 1 vs Class 4 modules determine user safety and enclosure requirements. Look for eye protection, emergency stop, protective covers, and interlocks when possible.
- Compatibility and integration: Check mounting compatibility (3018, 3018 Pro, or custom frames), connector types (PWM and 3-pin headers), and required power supplies (12V, power adapters, etc.).
- Software and workflow: Ensure compatibility with common laser software (LightBurn, LaserGRBL) and the ability to run offline or via USB/Wi-Fi. Consider modules with built-in control features for easier operation.
- Maintenance and longevity: Look for modules with proven diode longevity (often 20,000 hours or more) and reputable brands offering spare parts and reliable customer support.
- Price-to-performance balance: While higher wattage delivers more capability, evaluate whether your typical projects justify the added cost and required safety investments.
When choosing a laser head for a CNC system, consider your typical materials, required cut depth, enclosure situation, and software workflow. The options above span compact 4W modules suitable for light engraving to robust 10W–12W units designed for faster cutting and deeper engraving on thick woods, acrylics, and metals. Prioritize features that align with your projects, especially focus flexibility, air assist, and safety considerations to maximize throughput and accuracy.
