One of the recent technological developments in Laser Powder Bed Fusion (LPBF) process is use non-Gaussian beam profiles power density distributions. Irrespective strategies used to change profile, spatial shaping enhances flexibility since it allows manipulation thermal field, melt pool shape, and microstructure. This work showcases impact novel ring conventional Gaussian beams on density, characteristics, mechanical properties IN718 superalloy via LPBF. A laser source with capabilities...
Purpose This paper aims to investigate the processability by selective laser melting (SLM) of materials potential interest for innovative biodegradable implants, pure Fe and Zn. The these is evaluated with a more established counterpart in permanent stainless steel. In particular, processing conditions were studied reduce porosity due incomplete fusion powder. Design/methodology/approach first phase experiments, SLM AISI 316L was through design experiments method. study used identify...
The growing demand in lighter and safer structures generates the requirement of joining strategies, particularly for lightweight metal alloys, composites, also dissimilar materials together. Titanium alloys stand out as conventional choice light weight structures. Adhesive bonding titanium is an appealing route joint design, possibility it with materials. realization a strong depends not only on design type adhesive, but preparation adhering surface. Laser texturing presents advantages...
Complex geometries and fine critical features enabled by the powder bed fusion technologies are highly appealing for heat exchanger manufacturing. Copper is main metal of choice such applications. However, its processability using Selective Laser Melting (SLM) systems limited high reflectivity at 1 µm, emission wavelength laser sources commonly employed. Furthermore, conductivity pure copper, desirable final use products, causes instability difficulties in solidification. Resultantly,...
Laser powder bed fusion (PBF-LB) can be potentially used for producing patient-specific biomedical devices based on micro struts such as cardiovascular stents. NiTi alloys are an appealing choice their superelastic behaviour, while processing with PBF-LB poses several challenges. The final component is expected to have the correct transition temperature and mechanical properties along acceptable surface finish. All of these require a complete manufacturing cycle from production geometrical...
Abstract Incorporating lithium metal anodes in next‐generation batteries promises enhanced energy densities. However, lithium's reactivity results the formation of a native surface film, affecting battery performance. Therefore, precisely controlling chemical and morphological condition is imperative for producing high‐performance batteries. This study demonstrates efficacy laser treatment removing superficial contaminants from substrates. To this end, picosecond‐pulsed radiation proposed...
The use of laser beam welding with robotic manipulators is expanding towards wider industrial applications as the system availability increases reduced capital costs. Conventionally, requires high positioning and coupling accuracy. Due to variability in part geometry positioning, well thermal deformation that may occur during process, joint position fit-up are not always acceptable nor predictable a-priori if simple fixtures used. This makes passage from virtual CAD/CAM environment real...
