Additive Manufacturing (AM) methods are generally used to produce an early sample or near net-shape elements based on three-dimensional geometrical modules. To date, publications AM of metal implants have mainly focused knee and hip replacements bone scaffolds for tissue engineering. The direct fabrication metallic can be achieved by methods, such as Selective Laser Melting (SLM) Electron Beam (EBM). This work compares the SLM EBM in titanium analyzing microstructure, mechanical properties...
Nowadays, post-surgical or post-accidental bone loss can be substituted by custom-made scaffolds fabricated additive manufacturing (AM) methods from metallic powders. However, the partially melted powder particles must removed in a post-process chemical treatment. The aim of this study was to investigate effect polishing with various acid baths on novel scaffolds' morphology, porosity and mechanical properties. In first stage, Magics software (Materialise NV, Leuven, Belgium) used design...
ABSTRACT Bone tissue regeneration can be affected by various architectonical features of 3D porous scaffold, for example, pore size and shape, strut size, curvature, or porosity. However, the design additively manufactured structures studied so far was based on uniform geometrical figures unit cell structures, which often do not resemble natural architecture cancellous bone. Therefore, aim this study to investigate effect (aka printed) titanium scaffolds designed microtomographic scans...
NiTi alloys are widely used in different industrial and medical applications. Due to the inherent difficulty machining of these alloys, use Additive Manufacturing (AM) methods has become a popular method for their production. When working with there is requirement on precise control chemical composition, as this determines phase transition temperatures which responsible shape memory or superelastic behaviour. The high energies AM melt alloy leads nickel evaporation, resulting change between...
The use of laser 3D printers is very perspective in the fabrication solid and porous implants made various polymers, metals, its alloys. Selective Laser Melting (SLM) process, which consolidated powders are fully melted on each layer, gives possibility personalized based Computer Aid Design (CAD) model. During SLM a printer, depending system applied, there for setting amount energy density (J/mm³) transferred to powders, thus controlling porosity, contact angle roughness. In this study, we...
The use of elemental metallic powders and in situ alloying additive manufacturing (AM) is industrial relevance as it offers the required flexibility to tailor batch powder composition. This solution has been applied AM nickel-titanium (NiTi) shape memory alloy components.

To solve problem three different annealing heat treatments were...
A new powder production method has been developed to speed up the search for novel alloys additive manufacturing. The technique involves an ultrasonically agitated cold crucible installed at top of a 20 kHz ultrasonic sonotrode. material is melted with electric arc and undergoes pulverization standing wave vibrations. Several different in various forms, including noble metallic glass alloys, were chosen test process. atomized particles showed exceptional sphericity, while output suitable...
Nickel-titanium (NiTi) alloys have shown promise for a variety of biomedical applications because their unique properties shape memory, superelasticity, and low modulus elasticity (Young's modulus). Nevertheless, NiTi bulk components cannot be easily machined (e.g., CNC, rolling, grinding, casting, or press molding) due to thermomechanical sensitivity as well inherent superelasticity memory. Thus, powder bed fusion (PBF) additive manufacturing has been used successfully fabricate medical...
