Surface chemistry of Ti6Al4V components fabricated using selective laser melting for biomedical applications

Abstract: Selective laser melting (SLM) has previously been shown to be a viable method for fabricating biomedical implants; however, the surface chemistry of SLM fabricated parts is poorly understood. In this study, X-ray photoelectron spectroscopy (XPS) was used to determine the surface chemistries of (a) SLM as-fabricated (SLM-AF) Ti6Al4V and (b) SLM fabricated and mechanically polished (SLM-MP) Ti6Al4V samples and compared with (c) traditionally manufactured (forged) and mechanically polished Ti6Al4V samples. The SL… Show more

“…Selective laser melting (SLM), one of the most modern types of additive manufacturing (AM), is particularly well suited to fabricate customized implants or bone substitutes with free-form geometry [5][6][7]. Since the bone-implant interface is crucial to osseointegration, numerous studies have focused on evaluating the biocompatible properties of the SLM surface [8][9][10][11]. Compared to conventional machineprocessed titanium, the biocompatibility of SLM substrate remains controversial.…”

“…Therefore, powder particles close to the melt pool were partially melt and stuck to the vertical surfaces, see Figure 9. As reported by Jayasheelan et al [43], the rough nature of the SLM samples is due to the presence of partially melted particles on the surfaces of the fabricated samples. On the other hand, Figure 9 does not show a significant difference in the surface topology of the two samples.…”

“…Also, the research of 3T3 cell-cytotoxicity on the surface of Ti-6Al-4V obtained directly from 3D printing and subjected to polishing, did not indicate to any significant differences in cells behaviour [13]. The test carried out during the period of 7 days demonstrated that the cells were living on both surfaces, and that there was practically no dissolution of metals ions from the specimens in culture medium.…”

“…Simultaneously, research carried out by Vaithilingam et al [13] demonstrated that only Ti and Al are released from implants produced by the 3D printing technique. However, the presence of vanadium as well as associated vanadium oxides, i.e.…”
