Nanofractal surface structure under laser sintering of titanium and nitinol for bone tissue engineering

Metals for bone implants. Part 1. Powder metallurgy and implant rendering

“…For processing NiTi, the entire process is usually done in an enclosed chamber filled with Argon to minimize oxidation. While in principle it is possible to use elemental powder mixtures [137,138,[152][153][154], the majority of published results are from pre-alloyed NiTi powder [137-146, 148, 150, 151].…”

The biocompatibility of dense and porous Nickel–Titanium produced by selective laser melting

“…While NiTi-SMA are gaining interest for both engineering applications and for medical applications, AM of NiTi has received less attention so far. To date, there are almost a dozen international research papers or conference proceedings concerning the processing of NiTi via AM techniques [11][12][13][14][15][16][17][18][19][20]. This paper reports on the fitness and biocompatibility of additive manufactured NiTi parts as implant material.…”

Processing conditions and microstructural features of porous 316L stainless steel components by DMLS

“…Direct metal laser sintering (DMLS), as a typical solid freeform fabrication (SFF) technique, enables the quick production of complex shaped three-dimensional (3D) parts directly from metal powder [14][15][16][17][18]. The DMLS process creates parts in a layer-bylayer fashion by selectively fusing and consolidating thin layers of loose powder with a scanning laser beam.…”
