What are the key design considerations for additive manufacturing (DfAM)?

DfAM considerations include: Orientation optimization (affects surface finish, support needs, build time), Support structure minimization (design self-supporting angles >45 degrees), Wall thickness constraints (minimum depends on process, typically 0.4-1mm), Feature size limits (holes, gaps, fine details), Lattice structures and topology optimization for lightweighting, Part consolidation opportunities, Material-specific considerations (anisotropy, porosity), and Post-processing requirements (support removal, heat treatment, surface finishing). Effective DfAM enables parts impossible with traditional manufacturing while avoiding common AM pitfalls.
