Abstract
Imperative to the adoption of additive manufacturing for heat transfer applications is the understanding of as-built surface texture. In this work we analyze surface height data to determine the effect of build angle. Surface data is analyzed using existing and novel techniques and results are interpreted with respect to potential impact on heat transfer efficiency. Results show that complexity in the scan strategy of the build lead to difficulties developing correlation to existing techniques. Particles are also segmented from the surface and analysis of position show relationship to surface build angle, which may create stagnation points that detriment heat transfer.Citation
