36V PWM Powerful Water Cooling 450nm 120W Blue Diode Laser Module for Laser Cutting Machine

BU-Laser presents the industrial heavy-duty 450nm combined 120W blue laser module, integrated with multiple laser diodes, a high-efficiency beam combining optical path, a built-in 36V high-current PWM constant-current driver, and a professional circulating water cooling system. Delivering stable 120W real CW optical power, this high-energy blue laser light source is specially developed for industrial laser cutting, non-ferrous metal welding, large-format SLA 3D printing, galvanometer scanning precision processing, and mass-production light curing equipment.

Core Product Advantages

1. 450nm Blue Wavelength: Universal High Absorption for Multi-Material Processing

450nm ±3nm pure blue wavelength features high photon energy, with far higher absorption efficiency than infrared lasers on copper, aluminum, brass, and thin stainless steel. For non-metallic materials such as wood, acrylic, leather, PCB, and all types of photosensitive resin, it realizes clean cutting edges, minimal carbonization, and a low heat-affected zone.

Narrow spectral linewidth ≤5nm FWHM eliminates stray light interference, ensuring consistent processing precision and uniform curing effect;

Perfectly compatible with industrial tough resin, castable resin, ceramic resin, and flexible resin for high-speed 3D printing exposure.

2. Combined 120W Ultra-High Optical Power Boosts Mass Production Efficiency

Adopts multi-beam space combining technology to stack multiple laser emitters into one beam, reaching a total 120W stable CW output with 0–120W stepless power adjustment.

Compared with 30W–80W low-power blue modules, it greatly improves processing speed and material adaptability:

One-pass cutting: 22mm solid wood, 10mm acrylic, 1.6mm aluminum sheet, 1.0mm copper plate;

Supports thick-layer resin exposure up to 280μm for large-format industrial 3D printers;

Built-in closed-loop APC automatic power control, power stability ≤±0.4% within 24h full-power continuous operation, no power attenuation during long unmanned batch production, consistent cutting depth and curing energy for every workpiece.

3. Integrated 36V PWM Driver for Easy Industrial Integration

Standard DC 36V wide input voltage (34–38V tolerance), matching the power system of high-power CNC cutting machines, galvanometer equipment, and large industrial 3D printers.

Supports high-frequency PWM modulation (1–40kHz, 0–100% duty cycle) with fast response ≤40ns;

Synchronizable with galvanometer scanners, DMD exposure chips, and mainstream control software, including LightBurn, GRBL, and industrial motion control systems;

The driver circuit is fully encapsulated inside the housing; no extra external drive board is required, simplifying wiring and equipment assembly.

4. Heavy-Duty Water Cooling System for 24/7 Non-Stop Continuous Operation

Equipped with a high-flow circulating water cooling system, customized for a high heat load of 120W full power output:

Fanless, zero-noise internal structure without dust accumulation, suitable for clean workshops and sealed automated production lines; MTBF ≥ 10,000 hours for long-term heavy industrial use.
