Additive manufacturing of patient–specific lattice prosthetic sockets via field–driven design and elastic-plastic homogenization
In this paper, a digital workflow for the design of patient-specific prosthetic socket, that integrates clinical data, 3D scanning, and computational design, is implemented. The proposed methodology combines finite element analysis with a Field-Driven design approach, enabling the generation of optimized graded lattice structures. A PA12 socket manufactured by Multi Jet Fusion demonstrates up to 25% weight reduction, compared to a solid design, while maintaining adequate mechanical performance. Numerical, CT analyses and full-scale experimental validate the proposed framework for lightweight, personalized prosthetic device.

Lightweight design of polymeric thin-walled components: Latticization and elastic–plastic homogenization
In this published work the mechanical behavior of Polyamide 12 (PA12) lattice structures, produced with Multi Jet Fusion (MJF) is investigated, aiming to meet the demand for lightweight and structural strength. Combining experimental tests, simulations, and theoretical modelling, a homogenized material was proposed to predict the elastic–plastic response of these lattice structures. The model incorporates periodic boundary conditions, Hill’s yield criterion, and the Levy-Mises flow rule to account for anisotropic plasticity and directional hardening. Numerical results closely matched experimental data, demonstrating the model’s accuracy.
