The feature of Hybrid Laser Machine on Additive Manufacturing

Abstract

In this paper, we introduce a hybrid laser processing machine that employs directional energy deposition method in additive manufacturing. Since the hybrid laser processing machine can perform mechanical cutting by turning, milling and laser deposition, it is possible to build, coat and repair large structures.
The interference between the powder nozzle and the work piece in the conventional machine can be reduced by the single nozzle system. Stable deposition is achieved by monitoring the temperature at the melt pool and controlling the laser output to keep the temperature constant.
Titanium deposition is also possible by forming a localized argon atmosphere around the deposition area.
