Material Detail

A production-grade, mathematically rigorous Open Educational Resource (OER) module covering Design for Additive Manufacturing (DfAM) for undergraduate STEM mechanical and aerospace engineering curricula. The module explores first-principles thermal conduction penalties and overhang stability mechanics governing the 45-degree threshold, quantitative sizing rules across LPBF, SLS, SLA, and MEX processes, and print-in-place kinematic clearance requirements. Additionally, it addresses internal fluid channel geometry (teardrop and diamond cross-sections) and powder evacuation dynamics via the Beverloo discharge formulation. The module includes an embedded, client-side parametric DfAM rule calculator and a worked Lamé hoop-stress case study for high-pressure titanium hydraulic manifolds, aligned with Washington Accord (WA1–WA5) and EUR-ACE standards.
