Laser direct manufacturing (LDM) is intensively developed in recent years to directly and flexibly manufacture metallic components with full metal density, functions and properties, especially for some specific materials or geometry. This paper presents a project work on laser direct manufacturing a novel designed collimation component for out-space hard X-ray modulation telescope. The research work contained the characteristics study of overlap multi-pass laser cladding of tungsten or tungsten nickel alloys, the microstructure analyses and the processing stability of laser direct manufacturing. The research indicated that a triangle shape clad appeared when vertically overlap W and W90Ni10 alloy. The W60Ni40 and W45Ni55 alloys showed good forming capability for manufacturing. With optimized parameters
