Enhancing biocompatible metal alloy fabrication for bio implants through laser-based additive manufacturing (LBAM)

Abstract

Creating metal alloys that are durable and biologically suitable for medical implants is a significant focus of current medical science. Investigate using Laser-Based Additive Manufacturing (LBAM) methods in their creation to make these alloys more suitable for implantation in the human body. In addition to enabling the tailoring of mechanical characteristics and biocompatibility, laser-based Additive Manufacturing also provides fine control over the alloy's microstructure. Additive Manufacturing (AM) is a technological platform where 3D printing, scanning, and software technologies are used in designing, making products, and reverse engineering. This study explores the many facets of laser-based AM, including alloy composition, to shed light on the potential future of producing biocompatible metal alloys for bio-implants. The first step is a literature review on laser-based AM of biocompatible metal alloys for use in bioimplants. Then, the authors compared the systems according to many criteria, including Scanning Speed (SS), Hatch Distance (HD), Laser Power (LP), and Laser Thickness (LT). The maximum SS (1200 mm s−1) and the highest LP (385 W) were discovered using Ti metal alloy.
