Fragmentation and branch elimination are generally noticed in the conventionally processed Ti-6Al-4V. Such a key morphological change produces a positive change in certain mechanical properties. We, for the first time, observe fragmentation and branc

As-built, SLM-printed Ti-6Al-4V parts suffer from non-equilibrium, brittle microstructures due to the formation of metastable α’-phase martensite as a result of the printing process. Post-processing heat treatments are required to alleviate residu

Abstract In this study, the effects of surface roughness and pore characteristics on fatigue lives of laser powder bed fusion (LPBF) Ti–6Al–4V parts were investigated. The 197 fatigue bars were printed using the same laser power but with varied s

Selective Laser Melting is an additive manufacturing practice that permits the production of metal alloy-based parts. While facilitating the design of complex geometry, SLM leads to the fabrication of a unique material structure that showcases distin

Metallic powder reuse is a simple method to significantly reduce material cost for direct metal laser sintering; however, the recycled materials must not produce defects that compromise part performance. In this study, virgin 316L and 17-4PH stainles

Additive manufacturing techniques such as selective laser melting enable the production of customised components with high geometrical freedom. However, SLM results in a material condition with different properties to their conventionally manufacture

Though direct cost-savings are attainable with powder reuse in additive manufacturing (AM), the use of non-virgin material has raised concerns over as-built properties. Considerable efforts to validate feedstock recycling have examined static materia

Rib fractures and chest flail injuries are life threatening injuries that often require surgical treatment using metal (e.g. titanium) fracture reconstruction plates and screws. Current implant designs do not account for the variable stiffness presen
