LASER TREE 10000mW Engraving Module
The LASER TREE 10000mW Engraving Module delivers real 10W optical power with a compact form factor designed for CNC upgrades. It uses an original diode with FAC to shrink the beam at focus, boosting depth penetration and engraving precision. A 45mm fixed focus length supports fast engraving on stainless steel and ceramics, while the module’s air assist and built-in cooling help reduce burn marks and heat buildup. Notable improvements include a 20,000-hour diode lifetime and a 6mm air nozzle to reduce airflow resistance, enhancing cutting depth and edge quality.
Compatibility and installation emphasize ease of integration with common CNC routers. This module is advertised as class 1, suitable for hobby and light commercial applications, and supports PWM modulation for power adjustments at 5V. The combination of FAC-assisted focusing and robust cooling makes it a strong candidate for users upgrading entry-level engravers to handle tougher materials and faster workflows.
LASER TREE 60W+ Output Power Laser Module
This high-power 60W+ laser module is built for serious cutting tasks. It employs 12th high-performance diodes to deliver up to 60,000mW optical power, enabling faster cutting through thicker materials such as pine and plywood in a single pass. A switchable power mode allows users to choose between cutting power and precision engraving, adding versatility for mixed-material projects. The integrated air assist reduces charring and improves kerf quality, while a dual-fan cooling system supports stable performance during longer work sessions. It’s designed as a one-stop upgrade for more capable laser CNC setups.
Key considerations include power management, heat dissipation, and safe operation. The module’s higher power output demands careful alignment, sturdy mounting, and appropriate laser safety practices. Support for a range of materials—from wood to acrylic to some metals with proper settings—makes it a robust option for users expanding into heavy-duty engraving and cutting. The device’s comprehensive cooling and air-assist features help maintain performance consistency across longer runs.
LASER TREE 5W Engraver Module
The 5W LASER TREE module focuses on precision engraving and fine detail. With a fixed 45mm focus length, it can comfortably engrave 304 stainless steel and various woods. An upgraded air assist and heat dissipation design help produce cleaner edges and clearer cuts, reducing burn marks on delicate materials. The unit uses an original diode with FAC for stable, high-quality output and a 12V operating setup suitable for compact CNC machines. A compact form factor and easy assembly make this a practical upgrade for hobbyists seeking sharper, faster results with less material damage.
Designed with compatibility in mind, this module supports 5V PWM adjustment and convenient 3-pin control wiring. It balances a lower power profile with improved optical quality, making it a practical choice for those who primarily engrave and perform light-cutting tasks on wood, plastics, and certain coated metals. It’s especially suitable for upgrading smaller CNC machines where space and power budgets are considerations.
AENBUSLM 80W Laser Module With Air Assist
The AENBUSLM 80W Laser Module emphasizes both high power and reliable operation. It delivers 10W optical power with 80W machine power, enabling deep engraving and cutting through thicker materials like pine and black acrylic in a single pass. The built-in FAC shrinks the focal spot to boost cutting penetration and accuracy, while air assist improves edge cleanliness and reduces soot. A universal 12–24V input and 5V PWM modulation support offer flexible integration with a wide range of CNC systems. A robust cooling system ensures stability during extended use, backed by a durable diode lifetime.
Users should evaluate the module’s mounting compatibility, required air supply, and safety considerations for higher-power setups. The combination of FAC, air assist, and a compact footprint makes this option appealing for those upgrading mid-range machines to handle denser materials and more demanding engraving tasks without sacrificing control or precision.
Buying Guide: Key Considerations For Selecting A CNC Laser Module
- Power versus material compatibility: Higher optical power enables deeper cuts and faster engraving on denser materials, but it also demands stronger hardware and safety measures. Match power to your typical workload and materials.
- Beam quality and FAC: A built-in FAC (fast focus or field-adjustable focus) helps concentrate laser energy for cleaner edges, deeper penetration, and higher precision. Consider modules with FAC for improved performance on metal and ceramic if your work requires it.
- Air assist and cooling: Air assist reduces charring, improves edge quality, and speeds up cutting. Efficient cooling keeps the laser head stable during extended runs and prevents power drop-offs.
- Compatibility and mounting: Check whether the module fits your CNC upgrade kit (3018, 3018 Pro, or similar) and whether mounting hardware and connectors align with your machine’s control system (PWM, 3-pin connectors, and power input).
- Safety features: Look for eye protection options, enclosure compatibility, and class labeling. Modules with integrated eye protection and safe operation modes are beneficial for beginners and shared workshop environments.
- Reliability and service life: Diode quality and diode lifetime impact long-term costs. Modules with reputable brands and documented lifetimes offer greater return on investment.
- Wavelength and material compatibility: Most blue-violet 450 nm modules perform well on wood, plastics, and coated metals. Some specialized modules claim capabilities on mirror stainless steel and ceramics, but verify required settings and safety notes.
- Voltage and control interfaces: Ensure your CNC controller can provide the required input voltage, PWM range, and control signals. Some modules use 12V or 24V inputs and 5V PWM modulation for speed control.
When evaluating options, consider a balanced package: solid optical power, reliable FAC, integrated air assist, and effective cooling, all wrapped in a form factor that fits your CNC upgrade path. Reading product manuals and confirming compatibility with your machine’s spindle, enclosure, and controller will reduce setup issues and speed up deployment.
