From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

Advanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Recyclability of PLA and PLA-PBAT Compounds

Periodica Polytechnica Mechanical Engineering
In this study, mechanical recycling of polylactic acid (PLA) was investigated for up to 10 cycles. As expected, PLAs mechanical properties (tensile strength and modulus, charpy impact strength, heat deflection temperature) decreased after multiple rounds of recycling.

Extrusion Foaming of Semi‐Crystalline PLA and PLA/Thermoplastic Starch Blends

Macromolecular Bioscience, 2007
AbstractLow density open‐cell foams were obtained from polylactic acid (PLA) and from blends of PLA with thermoplastic starch (TPS) using CO2as a blowing agent. Two unexpected features were found. First, a 2D cavitation process in the fractured cell walls was unveiled.

Defect Evolution and Mechanical Performance of Fused Filament Fabrication‐Manufactured 17‐4PH Stainless Steel Revealed by X‐Ray Computed Tomography

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography reveals how process‐induced defects evolve from green to sintered states in Fused Filament Fabrication (FFF)‐manufactured 17‐4PH stainless steel. Internal porosity, weakest cross‐sections, and fracture locations show strong correlation with tensile performance, demonstrating the potential of computed tomography (CT)‐based ...
