How CO2 Lasers Work in Acrylic Cutting

At the heart of CO2 laser machines is a laser beam generated through an electrically stimulated mixture of gases, including carbon dioxide (CO2). The laser produces a high-powered, invisible infrared light (with a wavelength of 10.6 micrometers) that can easily be absorbed by non-metallic materials like acrylic. The concentrated light beam is directed through a series of lenses to focus on the work surface, which is acrylic in this case.

Once the laser beam comes in contact with the material, it heats the acrylic to a point where it melts or vaporizes, allowing for a clean, precise cut. The cutting process involves localized heat, which minimizes damage to surrounding material, giving CO2 laser machines an edge in fine-detail cutting.

Why Acrylic is Ideal for CO2 Laser Cutting

Acrylic (also known as PMMA) is an ideal material for CO2 laser cutting for several reasons:

• Transparency to Visible Light: Acrylic’s transparency allows it to interact efficiently with the infrared wavelengths of the CO2 laser.
• Thermal Reaction: When the high-energy laser beam interacts with acrylic, the heat causes localized melting, which can be controlled for precision cutting or engraving.
