Biomedical applications of the powder‐based 3D printed titanium alloys: A review

Reduced TiO2 Nanotubes/Silk Fibroin/ZnO as a Promising Hybrid Antibacterial Coating

“…Titanium and its alloys are commonly used materials in the medical field due to their properties [2] . Since titanium and its alloys are regarded as biologically inert materials, there are a variety of surface modification methods that enhance surface properties in terms of osseointegration during bone healing and antimicrobial activity [1b,3] . Changing the surface morphology, through nanostructures grown on Ti surface as nanotubes, could create a suitable platform for biomedical applications due to the advantages of high surface area.…”

3D printed electronics with nanomaterials

“…For all these techniques, the basic principle is that the pattern of each deposited layer of powder is converted into a continuous solid. This conversion can be achieved by Selective Laser Sintering (SLS), Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS), Electron Beam Melting (EBM), and by ink-jetting a binder on the layer of powder (Binder-Jet) that might be additionally sintered with an IR lamp in Multi-Jet Fusion techniques (MJF) [195][196][197][198][199] or post-processed in furnaces for sintering ink-jet binding metal powders like Metal-Jet. 200,201 As an example of powder techniques, in SLS, instead of a photocurable resin, a bed of polymer, ceramic, or metal powder is sintered (or melted for SLM) with a laser, 198,199 after that the bed retracts, a fresh layer of powder is rolled onto the top of the part, and the process repeats.…”

“…At the same time, some disadvantages are related to the high porosity of the final parts, and for high-temperature laser or electron beam processes, thermal stresses have to be considered as they can cause distortion to the printed part. 195,199 As for the VAT polymerisation techniques, the drawback for electronics applications is in the "one powder at a time" process, although bulk conductive metal parts are also possible to fabricate. And the same as for SLA, some attempts for multi-material fabrication will be presented in the Perspectives section.…”

“…В последние годы важным вектором развития материаловедения для медицины являются исследования и разработки, направленные на создание персонализированных медицинских изделий для остеоинтеграции, учитывающих анатомо-физиологические особенности каждого пациента [7,8]. Современные медицинские протоколы допускают использование в ряде случаев не типовых остеоинтегрируемых изделий, а персонализированных эндопротезов и имплантатов, изготовленных по CAD-моделям, полученным по результатам рентгенографии, компьютерной томографии и 3D-реконструкции [9].…”
