In Vitro Corrosion Resistance and Antibacterial Performance of Novel Fe–xCu Biomedical Alloys Prepared by Selective Laser Melting

et al. 2021

Antibacterial Fe-xCu biomedical alloys are designed to have a satisfactory biodegradation rate compared with pure iron. Fe-xCu (x ¼ 0, 1.5, 2.3, 7.8, and 10.1 wt%) alloys are produced by selective laser melting (SLM). Alloying with Cu has a significant influence on the grain size, hardness, biodegradation rate, and antibacterial performance of SLMed Fe-xCu alloys. Increasing Cu content decreases the grain size and increases the hardness. SLMed Fe-1.5Cu, Fe-2.3Cu, and Fe-10.1Cu have degradation rates similar to that of pure iron, while the degradation rate of SLMed Fe-7.8Cu is almost 2.5 times faster. The SLMed Fe-2.3Cu, Fe-7.8Cu, and Fe-10.1Cu produce strong antibacterial performance. The mechanisms of degradation behavior and antibacterial performance are clarified. SLMed Fe-7.8Cu had appropriate mechanical properties, satisfactory degradation rates, strong antibacterial performance, and good cytocompatibility, and therefore is a novel type of antibacterial biomedical alloy with good potential for clinical application.

“…The 3D printing machines, based on the stimulation used for integrating matter, can be categorized into (1) laser-based 3D printing technologies which operate using laser stimulation to bond either material powders or fluid medium; (2) extrusion-based 3D printing technologies which extrude molten materials that either cool and physically bond or are further solidified by UV stimulation, and (3) ink-based 3D printing technologies which print liquid or aerosol chemical binders to chemically bond the material powders together. Laser-based technologies include stereolithography (SLA) [118][119][120][121][122][123][124][125][126][127][128][129][130], selective laser sintering (SLS) [131][132][133][134][135][136], electron beam melting (EBM) [137][138][139], LENS [140], SLM [39,[141][142][143][144][145][146][147][148][149], and two-photon polymerization (2PP) [150,151]. Extrusionbased technologies include fused deposition modeling (FDM) [152], and material jetting (MJ) [96].…”

Background Bones in human body are prone to damage due to different causes such as fractures, diseases, and infections. Nevertheless, they have a remarkable capacity to repair and heal themselves after trauma and illness. Large defects, however, are never completely reinstated because their sizes are beyond the limit up to which the bones can repair [1]. In these conditions, therefore, a medical remedy is required to stabilize, align and support the damaged bone region to restore the lost function. Bone autografts are considered the gold standard treatment. However, they have a number of shortcomings including the limited sources and donor site morbidity. Allografts also have the risk of immune rejection and disease transmission [2, 3]. Therefore, the research has headed for other solutions via tissue engineering. Bone tissue engineering provides three-dimensional (3D)

Additive manufacturing (AM) of parts using a layer by layer approach has seen a rapid increase in application for production of net shape or near-net shape complex parts, especially in the field of aerospace, automotive, etc. Due to the superiority of manufacturing complex shapes with ease in comparison to the conventional methods, interest in these kinds of processes has increased. Among various methods in AM, laser powder bed fusion (LPBF) is one of the most widely used techniques to produce metallic components.
