Laser additive manufacturing with mixed powders of boron carbide and aluminum alloy is investigated.Parameters such as laser fortiflex stable super fork - head only power, scan speed, scan pattern, and hatching space are systematically evaluated and optimized to obtain the desired density and porosity.These results show that the AM part contains 20 wt% boron carbide and 80 wt% aluminum alloy, which are chiefs wine glass well mixed and synthesized during the melting process.Its mechanical properties are close to those of aluminum.A thin-wall structure based two dimensional and three dimensional radial collimators were fabricated with well-controlled geometry for neutron scattering measurement.
