Multi-material cellular structured orthopedic implants design: In vitro and bio...
Costa, M.M.; Lima, R.; Alves, N.; Silva, N.A.; Gasik, M.; Bartolomeu, F.; Miranda, G.In this study, Selective Laser Melting (SLM) was used to produce mono-material Ti64Al4V- and NiTi-cubic cellular structures with an open-cell size and wall thickness of 500 μm and 100 μm, respectively. Bioactive beta-tricalcium phosphate (βTCP) and polymer poly-ether-ether ketone (PEEK) were used to fill the produced structures open-cells, thus creating multi-material components. These structures were character...
Development of β-TCP-Ti6Al4V structures: Driving cellular response by modulatin...
Costa, M.M.; Lima, R.; Melo-Fonseca, F.; Bartolomeu, F.; Alves, N.; Miranda, A.; Gasik, M.; Silva, F.S.; Silva, N.A.; Miranda, G.Load-bearing implants success is strongly dependent on several physical and chemical properties that are known to drive cellular response. In this work, multi-material β-TCP-Ti6Al4V cellular structures were designed to combine Ti6Al4V mechanical properties and β-Tricalcium Phosphate bioactivity, in order to promote bone ingrowth as the bioactive material is being absorbed and replaced by newly formed bone. In t...
45S5 BAG-Ti6Al4V structures: The influence of the design on some of the physica...
Melo-Fonseca, F.; Lima, R.; Costa, M.M.; Bartolomeu, F.; Alves, Nuno; Miranda, A.; Gasik, M.; Silva, F.S.; Silva, N.A.; Miranda, G.Multi-material Ti6Al4V cellular structures impregnated with 45S5 bioactive glass were designed and produced using Selective LaserMelting (SLM), an additive manufacturing technique, combinedwith Press and Sintering focusing on load bearing components like hip implants. These structures were designed to combine Ti6Al4V mechanical properties and promote bone ingrowth into the structure as the bioactive material (4...
