“…Their results showed that productivity, process efficiency, and cutting edge quality obtained using fiber lasers outperform CO 2 laser performances. Teixidor et al [39] carried out an experimental study of fiber laser cutting of 316L stainless steel thin sheets. They analyzed the effect of laser parameters on the cutting quality for fixed nitrogen assistance gas.…”

From the introduction of stents, nobody was able to predict the advances that will occur in stent technology over the upcoming decades. Since their appearances, it became evident that this device had significant limitations, such as vessel occlusion and/or restenosis. Despite that, this medical device is the best clinical solution for cardiovascular vessel occlusions. Stents require a deep analysis, in terms of thrombogenicity, manufacturing process, geometrical aspects, and mechanical performance, among many other characteristics. The surface quality obtained in their manufacture process is crucial to blood compatibility, prevents the activation process of thrombosis, and improves the healing efficiency. The forecast stent market makes necessary continuous studies on this field, which help to solve the medical and engineering problems of this device, which are in constant development. Stents have been the center of many research lines over the last decades. The present chapter aims to summarize the state of the art of this medical device in the last years in the fields of design, manufacturing, and materials.

“…At low speed, laser power has little effect on dross formation. Teixidor et al [13] characterized geometrically dross height based on energy balances in fibre laser cutting. Muhammad et al [14] analyzed qualitatively the fibre laser cutting of stainless steel tube and the effect of introducing water flow in tubes on back wall dross formations.…”

The present paper describes an experimental study on influence of process parameters on dross properties in laser machining of AISI 304 material. Process parameters namely laser power, cutting speed and gas pressure are considered in the present work. Design of experiments is done using response surface methodology and analysis of variance is performed in order to identify significance and influence of process parameters on dross height. It is found that laser power and gas pressure are most significant parameters followed by cutting speed. Dross height increases with increase in laser power and decreases with decrease in gas pressure. On the basis of experimental analysis, a second order mathematical model is developed to predict dross height. Model predictions and experimental results are found in reasonable agreement. Further, optimization of process parameters is also performed to minimize dross height

“…One of the LBM technologies is laser cutting, which is often used in machine industry for processing almost all types of engineering materials, thus offering many applications too [3]. A widespread usage of this technology is machining of metallic materials, such as steels or non-ferrous metal alloys.…”

In the presented research, the methods of scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction and transmission electron microscopy were applied to analyse the powder waste obtained by cutting of AW-3103 aluminium alloy using a fibre laser. The scanning electron microscopy allows to analyse the morphology of the waste microparticles, the energy-dispersive X-ray spectroscopy revealed their chemical composition, which was compared with the composition of the original cut material. In the waste powder, mainly plate-like particles were observed that contain almost pure aluminium. X-ray powder diffraction measurements confirmed that the waste powder is composed of aluminium phase with only a slight presence of other phases (magnetite, austenite and graphite) and the transmission electron microscopy revealed the presence of nanoscale particles in this waste powder. Furthermore, it was found that the average size of the microparticles depends on the thickness of the cut material: particles obtained from a thicker workpiece were substantially bigger than those obtained from the thinner material. On the contrary, the dimensions of the workpiece have only a little impact on the particles’ shape and no significant influence on their chemical composition. The results also suggest that the microparticles could be used as an input material for powder metallurgy. But there is also a certain health risk connected with inhalation of such tiny particles, especially the nanoparticles, which can penetrate deep into the human pulmonary system.
