Additive Manufacturing Specifications

• Material: PETG & Polycarbonate (PC-CF with carbon fiber reinforcement)
• Layer Height: 0.16mm adaptive layer height for high-stress overhangs
• Infill: 40% Gyroid infill for isotropic mechanical shear resistance
• Dimensional Tolerances: $\pm 0.12\text{ mm}$ for press-fit bearing assemblies

Finite Element Analysis & Topology Optimization

Topology optimization removes non-load-bearing volume from brackets using SIMP (Solid Isotropic Material with Penalization):

$$E(\rho_e) = \rho_e^p E_0, \quad p \ge 3$$

Subject to the global compliance minimization constraint:

$$\min_{\boldsymbol{\rho}} c(\boldsymbol{\rho}) = \mathbf{U}^\top \mathbf{K} \mathbf{U} = \sum_{e=1}^N \rho_e^p \mathbf{u}_e^\top \mathbf{k}_0 \mathbf{u}_e$$
