Special Issue Information
Dear Colleagues,
Laser micromachining of materials has received a significant attention from both research communities and various industries in recent years due to its wide ranges of applications such as Metal Additive Manufacturing, laser polishing, laser hardening, in situ alloying, etc. Laser Powder Bed Fusion (L-PBF), which is a branch of Metal Additive Manufacturing, produces parts layer by layer, utilizing a controlled laser beam to melt the metal powder layer in a specific scan path which is defined by slicing the geometry of the CAD file. Thus, it can produce almost any complex geometry efficiently, demonstrating strong potential in fabricating implants for biomedical application. Additionally, laser polishing has evolved significantly due to its strong potential in replacing mechanical polishing in improving the surface finishes of hard materials such as Ti6Al4V. Thus, laser micromachining technologies demonstrate a promising future in biomedical applications.
Besides the process itself, the application of biocompatible material in the laser micromachining process is also evolving and has become an attractive research area. Many researchers have utilized the laser-based coating process to deposit biocompatible material on a metal implant. For instance, in one of our recent works, composite coatings consisting of fluorapatite mixed with 20 wt% yttria (3 mol%) stabilized cubic phase zirconia (c-ZrO2, 3Y-TZP) or 20 wt% alumina (a-Al2O3) were deposited on Ti6Al4V substrates using a Nd:YAG laser cladding system. The interface morphology, phase composition, micro-hardness and biological properties of the two coatings were examined and compared, and the coated specimens had good vitro bioactivity.
This Special Issue aims to cover recent advances in the field of laser micromachining for bio-medical applications. The articles collected in this Special Issue include, but are not limited to, the application of metal 3D printing for biomedical implants, the mechanical and bio properties of a lattice structure for biomedical implants, bio-mimicry design, laser material processing for biomedical applications, computational laser material processing, biocompatible material, a laser-based biocompatible material process and metallic glasses for biomedical applications. Topics are also open for laser micromachining-based related research.
