CLAMIR: LMD/DED processes

Continuous control of the laser
Avoids overheating of the part under process and allows a continuous and high quality manufacturing process.

Reduces rates of defective parts, material reduction cost up to 60% and saves 50% more energy than uncontrolled processes.

CLAMIR: LMD/DED processes

Constant laser power causes overheating and lack of adherence to the base material.

Laser power is closed loop controlled in real time using the information extracted from the melt pool IR images.

CLAMIR: Cladding processes

Reduces damage
To the base material due to excess of laser power application (average reduction of dilution: > 40%)

Allows continuous processing
Increasing productivity.
