Build Orientation Optimization Based on Weighted Analysis of Local Surface Region Curvature

摘要: Build orientation becomes a hot issue in 3D printing, which has significant impact on the surface quality, support structure and final cost of fabricated model. In this paper, we focus our attention quality part when by printer under certain specific build orientation. A novel method using curvature shift is proposed to search local regions with obvious changes model printed. Based strategy, divided into separate can be treated differently. Every triangle facet given different weight factor calculating average each region. Weighted facets introduced building volume error function. Candidate obtained eigenvalue decomposition optimal one leads minimal From case study, gets smaller lower printing time, means higher weighted
