Review load-bearing FDM/material-extrusion parts using process-specific evidence, printed orientation, walls and infill, anisotropy, creep, fatigue, environmental exposure, and coupon planning. Use when sizing a functional printed bracket, enclosure, boss, insert, snap-fit, beam, or lattice; when choosing walls versus sparse or solid infill; when interpreting PLA, PETG, ABS, ASA, nylon, or composite data; or when deciding whether effective properties, explicit lattice FEM, coupons, proof tests, or an engineer are required.
