Coaxial Laser Wire Deposition

Abstract

The new coaxial fine wire deposition optic presents reduced weight (∼10 kg without fiber and wire feed) and has extended functionality. The optical components are designed for wavelengths of 450 – 550 nm and 890 – 1100 nm. The head is prepared for the processing of even thin wires down to 100 μm in diameter. The new system is equipped with an integrated mini camera, sensors and interfaces to control units and networks. As a result the new head exhibits potential to produce very precise metallic structures as low as 200 - 300 μm. Suitable materials are steel, titanium, nickel and cobalt base alloys as well as materials on the basis of copper.
