“…Relevant researches on the selective laser melting (SLM) fabricated NiTi alloy are mainly concentrated on the processing optimization with both pre-alloying powder [6][7][8][9][10][11][12][13][14][15][16][17][18] and mixed pure powders [19] as starting powder materials, the measurement of martensitic transformation temperatures [6][7][8][9][10][11][12][13][14][15][16][17][18], the detection of the stress or strain-induced martensitic transformation from different thermomechanical conditions [10,12,15,[16][17][18], the effect of post-heat treatment [10,12], evaluation of other functional properties such as the damping properties [6] and the fatigue behavior [13,14]. Based on these numerous investigations, it is worth noting that it exists large discrepancies in results, especially in terms of the final mechanical properties and shape memory effects.…”

“…As the origin of functional properties of NiTi alloy, the MT indeed plays a crucial role in the final processing and optimization. That is why the MT temperatures [6][7][8][9][10][11][12][13][14][15][16][17][18] and the critical stress inducing the martensitic transformation [10,12,15,[16][17][18] are widely investigated by most of…”

“…No functional grading has yet been demonstrated along the X-Y plane of biomedical alloys within a single component. However, alternating layers of microstructures have been produced in a NiTi shape memory alloy, with alternate austenitic and martensitic structures inducing the Elinvar effect, where the temperature dependence of stiffness is negligible [240]. A similar high degree of microstructural control has been demonstrated over low modulus Ti-15Mo-5Zr-3Al alloy, preferentially generating either < 001 > and < 011 > orientations along the build direction [239].…”

A B S T R A C TFor over ten years, metallic skeletal endoprostheses have been produced in select cases by additive manufacturing (AM) and increasing awareness is driving demand for wider access to the technology. This review brings together key stakeholder perspectives on the translation of AM research; clinical application, ongoing research in the field of powder bed fusion, and the current regulatory framework. The current clinical use of AM is assessed, both on a mass-manufactured scale and bespoke application for patient specific implants. To illuminate the benefits to clinicians, a case study on the provision of custom cranioplasty is provided based on prosthetist testimony. Current progress in research is discussed, with immediate gains to be made through increased design freedom described at both meso-and macro-scale, as well as long-term goals in alloy development including bioactive materials. In all cases, focus is given to specific clinical challenges such as stress shielding and osseointegration. Outstanding challenges in industrialisation of AM are openly raised, with possible solutions assessed. Finally, overarching context is given with a review of the regulatory framework involved in translating AM implants, with particular emphasis placed on customisation within an orthopaedic remit. A viable future for AM of metal implants is presented, and it is suggested that continuing collaboration between all stakeholders will enable acceleration of the translation process. fection or surgical complications [11][12][13].Currently, the majority of skeletal endoprostheses are produced from titanium (Ti) or cobalt chromium (CoCr) based alloys, which meet the criteria of durability, strength, corrosion resistance and a low immune response [14,15]. These characteristics however come at the cost of the high stiffness of these alloys in comparison to bone. Mismatch between the mechanical properties of bone and orthopaedic materials

The use of conventional manufacturing methods is mainly limited by the size of the production run and the geometrical complexity of the component, and as a result we are occasionally forced to use processes and tools that increase the final cost of the element being produced. Additive manufacturing techniques provide major competitive advantages due to the fact that they adapt to the geometrical complexity and customised design of the part to be manufactured. The following may also be achieved according to field of application: lighter weight products, multimaterial products, ergonomic products, efficient short production runs, fewer assembly errors and, therefore, lower associated costs, lower tool investment costs, a combination of different manufacturing processes, an optimised use of materials, and a more sustainable manufacturing process. Additive manufacturing is seen as being one of the major revolutionary industrial processes of the next few years. Additive manufacturing has several alternatives ranging from simple RepRap machines to complex fused metal deposition systems. This paper will expand upon the structural design of the machines, their history, classification, the alternatives existing today, materials used and their characteristics, the technology limitations, and also the prospects that are opening up for different technologies both in the professional field of innovation and the academic field of research. It is important to say that the choice of technology is directly dependent on the particular application being planned: first the application and then the technology.
