Selective Laser Sintering an overview

Selective laser sintering (SLS) is another early 3D printing process developed at University of Texas at Austin by Carl Deckard, who later founded DTM Corp. (later acquired by 3D Systems). Fig. 28.2 depicts Deckard’s invention [9],in which a scanning laser fuses small particles, on the order of 50 μm in diameter, to build-up parts layer by layer.

Selective Laser Melting an overview ScienceDirect

Selective laser melting (SLM) is a specific 3D printing technique, which utilizes high power-density laser to fully melt and fuse metallic powders to produce near net-shape parts with near full density (up to 99.9% relative density). From: Nano Today, 2017. Download as PDF.

Selective laser melting (SLM) is a commonly-used technique for processing high strength aluminum alloys. The selection of SLM process parameters could control the microstructure of parts and their mechanical properties. However, the process parameters limit and defects obtained inside the as-built parts present obstacles to customized part production. This study investigates the influence of SLM

Glaucoma surgery Wikipedia

Selective laser trabeculoplasty is newer technology that uses a Nd:YAG laser to target specific cells within the trabecular meshwork and create less thermal damage than ALT. SLT shows promise as a long term treatment. In SLT a laser is used to selectively target the melanocytes in the trabecular meshwork. Though the mechanism by which SLT functions is not well understood, it has been shown in trials to be as effective as the older Argon Laser

The laser-based powder bed fusion (LBPF) process or commonly known as selective laser melting (SLM) has made significant progress since its inception. Initially, conventional materials like 316L, Ti6Al4V, and IN-718 were fabricated using the SLM process. However, it was inevitable to explore the possible fabrication of the second most popular structural material after Fe-based alloys/steel, the Al

01/02/2021 A related process is called selective laser sintering (SLS); here the nozzle head and liquid binder are replaced by precisely guided lasers that heat the powder so that it sinters, or partially melts and fuses, in the desired areas. Typically, SLS works with either plastic powder or a combined metal-binder powder; in the latter case the built-up object may have to be heated in a furnace for

In the initial phase, directly after injection of a pump pulse into the gain medium, the laser resonator contains frequency-selective elements, which introduce some losses and could not tolerate a high power level, but allow for the build-up of light with a narrow linewidth. Once a certain power level has been reached, the Pockels cell is switched, and this reconfigures the laser resonator so
