Introduction

The capabilities of large laser engravers in processing a variety of materials have seen significant advancement. This article provides a detailed examination of the types of materials that can be processed using large laser engravers, focusing on specific parameters and the numerical aspects of laser engraving efficacy.

Materials Suitable for Laser Engraving

Metals

Laser engravers are highly effective on various metals. Common metals include stainless steel, aluminum, brass, copper, and titanium. The engravers can achieve a precision level of up to 0.001 inches, making them ideal for intricate designs and serial markings.

Plastics

Materials such as acrylic, polycarbonate, and ABS are suitable for laser engraving. Specific power settings depend on material thickness; for instance, acrylic requires about 10 watts for 1/8 inch thickness. The absorption rates of these materials influence the quality of the engraving.

Wood and Paper

For wood, engravers can work with both hardwoods and softwoods. Typical settings might include a speed of 400 mm/s and a power level of 50% for hardwoods. Paper absorbs laser energy well, allowing for fast processing speeds and fine detail.

Glass and Ceramics

Engraving on glass requires precision and low power settings to prevent fractures, often using a frosted appearance. Ceramics may need a diode-pumped laser operating at different wavelengths for effective results.

Textiles

Laser engravers can cut and engrave textiles such as cotton, polyester, and felt. The laser's speed and power settings are crucial for preventing burns or damage, with typical speeds around 500 mm/s.

Composite Materials

Materials like fiberglass and carbon fiber composites can be engraved, although high power settings are required due to their density. The exact laser parameters depend on the matrix material within the composite.
