The widespread adoption of additive manufacturing (AM) techniques in biomedical device production, especially with shape memory materials like NiTi alloys, is well-established due to their unique properties. However, traditional manufacturing techniques face limitations when working with these alloys, prompting high interest in AM research, with a special focus on the Selective Laser Melting (SLM) technique. In this study, a comprehensive analysis of the printing conditions for NiTi alloys depositions through the SLM technique was conducted. With the support of a previously explored analytical approach, experimental trials were designed to investigate the printability of the NiTi alloy. NiTi samples were produced using an SLM machine with a maximum laser power of 500 W, operating in continuous mode (also called pulsed), and with two different layer thicknesses, i.e. 30 μm and 60 μm. Experimental analyses, including optical and electron microscopy were carried out to assess the microstructural characteristics of the printed samples. Our findings enabled a preliminary exploration of the material's printability.

Abstract
The widespread adoption of additive manufacturing (AM) techniques in biomedical device production, especially with shape memory materials like NiTi alloys, is well-established due to their unique properties. However, traditional manufacturing techniques face limitations when working with these alloys, prompting high interest in AM research, with a special focus on the Selective Laser Melting (SLM) technique. In this study, a comprehensive analysis of the printing conditions for NiTi alloys depositions through the SLM technique was conducted. With the support of a previously explored analytical approach, experimental trials were designed to investigate the printability of the NiTi alloy. NiTi samples were produced using an SLM machine with a maximum laser power of 500 W, operating in continuous mode (also called pulsed), and with two different layer thicknesses, i.e. 30 μm and 60 μm. Experimental analyses, including optical and electron microscopy were carried out to assess the microstructural characteristics of the printed samples. Our findings enabled a preliminary exploration of the material's printability.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
