Metallic porous structures (scaffolds) produced by additive manufacturing represent an important class of personalised implants used in load-bearing orthopaedic applications. As such, their fatigue performance must be excellent to prevent the need for revision surgery. This paper provides insight into high-cycle behaviour novel titanium scaffolds with hierarchical porosity and properties comparable those human bone that were direct ink writing (DIW) tested under cyclic loading typical...
Abstract This contribution focuses on the nitriding of hierarchically porous titanium scaffolds to enhance their fatigue behaviour. Firstly, recent experimental findings that demonstrate benefits intra-filament porosity in improving resistance are discussed, providing details crack growth shielding micromechanisms. Subsequently, study explores application as a promising technique prolong initiation. The scaffolds, prepared using direct ink writing method with ~ 6% and inter-filament 68%,...
The article introduces a two‐level finite element model for metallic scaffolds with porosity at both design and material levels. Despite several additive manufacturing methods producing structures controlled hierarchical porosity, their functional properties remain largely unknown, hindering industrial utilization. This examines how microporosity affects the mechanical of scaffold prepared by direct ink writing from pure titanium dimensions typical orthopedic implants. study focuses on...
Additive manufacturing of titanium porous structures by direct ink writing involves the removal binder needed for powder extrusion and subsequent sintering to consolidate 3D-plotted body. In this work, pressure-less spark plasma (PL-SPS) was systematically studied fast consolidation structures. Furthermore, poloxamer 407 used as lowest temperature possible identified its thermal elimination. The results show first time that PL-SPS generated conditions similar those conventional sintering,...
