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 leads 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.

用于传热应用的激光粉末床融合表面的表征

在传热应用中采用增材制造的必要条件是了解竣工表面纹理。在这项工作中，我们分析表面高度数据以确定构建角度的影响。使用现有和新技术分析表面数据，并根据对传热效率的潜在影响来解释结果。结果表明，构建扫描策略的复杂性导致难以与现有技术建立关联。粒子也从表面分割，位置分析显示与表面构建角度的关系，这可能会产生不利于传热的停滞点。
