4. When Comparing The LP4 With LaserPecker 2/3, Which One Should I Choose?
We believe the model choice mainly depends on the material you intend to work with. LaserPecker 2 (LP2) is a 450nm diode laser, ideal for engraving on wood, leather, and certain types of metal like 304 stainless steel, coated metal, and oxidized metal. However, bare metals require additional pretreatment. LaserPecker 3 (LP3) is a 1064nm infrared laser capable of engraving on almost all metals, plastic, and some stones. The LaserPecker 4 features a dual laser system, combining the 450nm diode laser and 1064nm infrared laser, making it suitable for engraving on almost all materials.
