Researchers have developed a machine learning approach to predict the optimal build orientation for dental parts manufactured using selective laser melting (SLM). By training models on approximately 2400 patient-specific dental parts, they compared the effectiveness of various rotation representations, including classical SO(3) parameterizations and direct S2 representations. The study found that test-time augmentation significantly improved accuracy across most representations, reducing mean angular error by 31-73%. While direct S2 representations showed promising results, the best-performing representation was found to be backbone-dependent. AI
