Abstract Additive manufacturing (AM) is able to generate parts of a quality comparable those produced through conventional manufacturing, but most the AM processes are associated with low build speeds, which reduce overall productivity. This paper evaluates how increasing powder layer thickness from 20 µm 80 affects speed, microstructure and mechanical properties stainless steel 316L that using laser bed fusion. A detailed characterization was performed scanning electron microscopy,...
Parts produced by Selective Laser Melting (SLM) presents a roughness due to thickness of fusion layers but also partially sintered particles stuck the edge parts. In order ensure finished product with dimensional and structural requirements an industrial part, post processing machining is necessary. The aim proposed study compare machinability Ti-6Al-4 V obtained SLM process that cast alloy. Micro-cutting tests are conducted examine effect operating conditions on cutting forces, chip...
Contour scanning and process gas type are parameters typically considered achieving second order effects compared to first factors such as laser power speed. The present work highlights that contour is crucial ensure geometrical accuracy thereby the high performance under uniaxial compression of complex Alloy 718 lattice structures. Studies X-ray computed tomography visualizations as-built compression-strained structures reveal continuous smooth bending walls, earlier onset internal contact...
Abstract Additive manufacturing (AM) using powder bed fusion is becoming a mature technology that offers great possibilities and design freedom for of near net shape components. However, many gas turbine aerospace applications, machining still required, which motivates further research on the machinability work piece integrity additive-manufactured superalloys. In this work, turning tests have been performed components made with both Powder Bed Fusion Laser Beam (PBF-LB) Electron (PBF-EB) in...
Metastable beta titanium alloys TixNb (22at%<x< 27at%) are excellent candidates for biomedical applications because of their very low elastic modulus close to that cortical bone, biocompatibility and high strength. The flexibility the selective laser melting (SLM) process enables manufacturing complex parts, such as custom-made implants but also fusion a wide range alloys. In this study, microstructural properties TiNb alloy elaborated by SLM mixture Ti Nb powder (26at%) were investigated....
After a joint replacement, stress-shielding phenomenon often appears resulting from Young's modulus mismatch between the implant and cortical bone. In accordance with Wolff's law, it will result in bone resorption could lead to loosening of implant.Ti-Nb beta metastable alloys are excellent candidates for biomedical applications because their very low elastic close that high strength. This material, associated direct laser deposition or CLAD® process allows fabrication biomimetic implants....
