Ortur Laser Master 3 – High Precision 20W Diode Laser Engraver and Cutter

The Ortur Laser Master 3 20W version offers a powerful upgrade for creators who need more cutting strength and engraving speed without compromising on precision. Built for makers, artists, small businesses, and professionals, this 20W diode laser engraver delivers clean, high-speed results across a wide variety of materials including wood, acrylic, leather, stainless steel, and more.

True 20W Optical Laser Power

Powered by Ortur’s advanced LU3-20A laser module, the 20W version uses COS packaging technology to combine multiple laser beams into a single, ultra-focused output. This delivers true 20-watt power—strong enough for one-pass cutting through materials such as:

15 millimeters pinewood

10 millimeters plywood

8 millimeters black acrylic

Whether you’re cutting or engraving, this laser is optimized for power, precision, and speed.

Ultra-Fine Precision for Detailed Engraving

The compressed square laser spot measures just 0.08 by 0.08 millimeters, enabling 256 levels of grayscale engraving for smooth gradients and sharp image detail. This makes it ideal for photo engraving, fine line work, and intricate designs on various surfaces.

Enhanced Color Engraving on Stainless Steel

With the right engraving parameters, the Ortur 20W laser can unlock over 380 vivid colors on stainless steel. This advanced capability allows users to create full-spectrum artwork and logos far beyond traditional monochrome laser engraving.

Built-In Air Assist for Cleaner Results

The LU3-20A module includes a built-in air tube, designed to work with the included Ortur Air Pump 1.0. This 50-liter-per-minute pump reduces burn marks by up to 50 percent, improves cutting edge clarity, and keeps your workspace clean.

Advanced Cooling System for Long-Term Durability

The dual high-speed cooling fans operate at up to 10,000 RPM, ensuring your laser stays cool during extended use. Airflow-guided blinds direct dust away from the lens, preserving optical clarity and reducing maintenance.
