Understanding Laser Plotters and Galvo Laser Markers
What are Galvo Laser Markers?
Galvo laser markers use mirrors to guide the laser beam, offering speed and precision. 2D models work on flat surfaces, while 3D models handle curved materials. They’re perfect for detailed designs, used in industries like electronics and jewelry, and are ideal for mass production due to their compact size and speed.
What is a Laser Plotter?
A laser plotter is a flatbed laser machine that cuts and engraves with precision. It uses a gantry system to move the laser head along X and Y axes, making it ideal for large materials. Commonly used for signs, woodworking, and textiles, it works well with wood, acrylic, and fabric. Great for large tasks.
Key Differences in Motion Mechanisms
Laser Plotters (Gantry System): The laser head moves across the material for accurate cutting and engraving. Best for large materials, but slower for detailed tasks.
Galvo Lasers (Galvanometer Mirrors): Small mirrors guide the laser beam, making the system fast and precise. Ideal for intricate designs and smaller areas, with high speed for detailed work.
