Mechanical Analysis and Simulation of 3D‐Printed Femur Segments With Biomimetic Porosity

Material Design &Processing Communication, Volume 2026, Issue 1, 2026.
Three‐dimensional (3D) printing has transformed medical engineering by enabling customized bone prostheses. This study designs and evaluates a 3D‐printed femur segment with manually crafted porosity mimicking natural bone tissue. Mechanical performance is assessed through compression testing, dynamic simulation, fatigue analysis, and crack propagation.

Determination of Crystallization Kinetics of Polyetheretherketone in Material Extrusion Process Using Numerical Simulation

Polymers for Advanced Technologies, Volume 36, Issue 12, December 2025.
ABSTRACT Despite considerable progress over the past 3 years, some issues remain in obtaining printed polyetheretherketone (PEEK) parts printed by the material extrusion process (MEX). The fast crystallization of PEEK during printing results in distortion, poor dimensional accuracy, and low inter‐filament adhesion.
