Experimental Study of L-PBF Micro-channel Surface Roughness: An Experimental Study on the Effects of Build Angle on Surface Roughness and Fluid Flow Performance in Laser-Powder Bed Fusion manufactured Micro-channels

Progress in Laser powder bed fusion manufacturing has led to greater use of Additive Manufacturing in combustion chambers/nozzles. This allows for the creation of more intricate and efficient solutions, but generates the need for a better understanding of how surface roughness in micro-channels used for engine cooling relates to build angle and...
