}

Functionally-graded material (FGM) deposition in multi-material AM.

Describes a composition transition between two constituent materials along the build direction using a power-law profile.

Fields

e_a: f64

Young’s modulus of material A (Pa).

e_b: f64

Young’s modulus of material B (Pa).

rho_a: f64

Density of material A (kg/m³).

rho_b: f64

Density of material B (kg/m³).

k_a: f64

Thermal conductivity of material A (W/m·K).

k_b: f64

Thermal conductivity of material B (W/m·K).

grading_exponent: f64

Power-law exponent n for the grading profile. n=0 → pure A; n→∞ → pure B; n=1 → linear.

grading_height_m: f64

Total build height over which grading occurs (m).
