3. Product Overview
3.1 Dual Integrated Laser System
The P1 combines two distinct laser modules for enhanced versatility:
- 5W Diode Laser (455 nm): Ideal for cutting and engraving non-metallic materials such as wood, bamboo, paper, leather, cardboard, cork, stone, and felt. It delivers clear and defined results.
- 1.2W Infrared Laser (1064 nm): Excels in marking and engraving challenging materials with high precision, including all metals (stainless steel, aluminum, copper, iron, gold, silver, platinum, titanium), plastics, and opaque dark acrylic.
3.2 High Speed and Precision
The P1 features a CoreXY design with dual motors, enabling high-speed operations and precise detailing.
- Engraving Speed: Achieves speeds of up to 10,000 mm/min.
- Laser Spot Size: The compressed laser spot ensures fine details and precise cuts. The diode laser has a spot size of 0.08 × 0.06 mm, and the infrared laser has a spot size of 0.03 × 0.03 mm.
