How Does 3D Laser Cutting Work?
Laser Sources
The most common laser sources used in 3D laser cutting are:
- Fiber Lasers: Compact and efficient, providing high power and beam quality.
- CO2 Lasers: Powerful and versatile, suitable for cutting a wide range of materials.
Beam Manipulation
The laser beam is manipulated using various optical components:
- Mirrors: Direct and steer the beam along the desired path.
- Lenses: Focus the beam to achieve the required power density.
- Beam Expanders: Increase the beam diameter to improve cutting speed and reduce heat-affected zones.
Material Interaction
The laser beam interacts with the material in one of three ways:
- Melting: The laser beam melts the material, and the molten material is removed by an assist gas.
- Vaporization: The laser beam vaporizes the material, creating a clean and precise cut.
- Sublimation: The laser beam directly converts the material from solid to gas, leaving no residue.
Cutting Path
The cutting path is determined by the CAD design and is controlled by a computer numerical control (CNC) system. The CNC system guides the laser beam along the desired trajectory, ensuring precision and accuracy.
Materials Suitable for 3D Laser Cutting
