LASER TREE 10W Engraving Module With Air Assist
The LASER TREE 10W engraving module offers 10W optical output with a built-in FAC for smaller focus spot and improved penetration. It features an upgraded air assist system and a 45mm focus length, enabling faster engraving on stainless steel and reliable cutting on plywood and other materials. The module is designed for Class 1 safety with a compact form factor and 24V input, making it a straightforward upgrade for compatible CNC routers and laser engravers. The included features aim to boost engraving precision and edge quality, particularly on reflective metals.
LASER TREE 60W+ Power Module For Stronger Cuts
The 60W+ LASER TREE module provides robust cutting power for thicker materials like hardwoods and acrylics. It uses a multi-diode arrangement capable of delivering up to 60000mW optical power. Features include a power-switching mode to select 60W, 40W, or 20W, along with integrated air assist and dual-fan cooling to optimize cutting depth, speed, and stability during extended runs. Designed for upgrade paths on various CNC platforms, it emphasizes fast switching between heavy-cut and precise engraving modes.
LASER TREE 5W Engraver Module For Upgrades
This 5W optical output module targets compact CNC upgrades. It supports direct engraving on 304 stainless steel with a faster pace at 40mm focus length and offers clean edge results on plywood with a top speed suitable for hobbyist workflows. The unit includes a magnetic removable eye protection feature and a compact, robust aluminum housing. It suits 3018-style CNC machines and other small-format routers, enabling precise, small-scale engraving and light cutting tasks.
LASER TREE 10W Engraver Module With FAC And Air Assist
This 10W module combines a real 10W optical output with built-in FAC for a tighter focus spot (0.08 x 0.08 mm). It is designed for compatibility with 3018-based machines and similar CNC setups, offering a balance of engraving speed (up to 300 mm/s at 45 mm focus) and cutting depth (up to 8 mm plywood in one pass). The module embraces a dual-faceted approach: air assist improves edge cleanliness and deeper penetration, while a robust copper-aluminum construction supports stable operation and longevity. The system supports 24V input and PWM modulation for power control.
AENBUSLM 80W/10W Air-Assist Module
The AENBUSLM module family includes options with 10W optical power, 45mm focus, and integrated air assist and FAC for tighter beam control. The 80W machine power designation indicates a strong-class diode system designed for high-speed cutting and engraving on stainless steel, wood, and plastics. A built-in cooling fan and a 12V-24V universal input expand compatibility with a range of CNC platforms. The FAC ensures a smaller focal spot, improving penetration and edge quality during cutting and engraving tasks. This module is suitable for upgrading standard CNC routers to handle more demanding materials.
Buying Guide: Key Purchase Considerations For CNC Upgrades
When choosing a laser module for CNC upgrades, consider laser power needs, beam quality, and how the module integrates with your machine. Do you require high-speed engraving on metal or deeper cuts in plywood? Look for FAC-enabled diodes for smaller focus spots that improve resolution and penetration. Air assist can dramatically improve edge cleanliness and reduce burn marks on dense materials. Cooling is essential for sustained operation, especially during lengthy jobs. Compatibility matters: confirm mounting patterns, electrical interfaces (PWM, voltage), and connector types with your CNC controller and upgrade bracket. Compare modules that offer adjustable focus or multiple power modes to optimize for both engraving and cutting. For safety, verify that the module is Class 1 compliant or that protective features (eye protection and shielding) are included or easily added. Finally, assess the availability of spare parts, replacement diodes, and service life estimates to ensure long-term reliability for your workflow.
