Laser‐Sintered Barium Titanate
Journal of the American Ceramic Society, 1989Laser sintering of alkoxy‐derived ultrafine BaTiO 3 powders was investigated. The temperature increases of the sample with laser irradiation were measured with a thermocouple. It was found that laser irradiation could generate enough heat to sinter ceramics. A slurry was prepared by mixing an

Laser sintering is a popular additive manufacturing technology, particularly for service parts. Invented by C. Deckard in the mid-1980s, the approach of using a laser to densify a powder bed selectively has been extensively researched and has been applied to metals, ceramics, polymers and composites.

Industrial laser micro sintering
ICALEO 2004: 23rd International Congress on Laser Materials Processing and Laser Microfabrication, 2004As mechanical engineering industry encounters a growing demand of µm-sized or µm-structured components for an increasing range of applications, miniaturization is presently ranking among the most important goals in product and tool development. Compared to still higher resolving techniques, selective laser sintering (SLS) still bears the

Over the last decade, several RP methods have been developed as techniques to directly or indirectly fabricate ceramic parts. Each process has its own characteristics, advantages and disadvantages. To make a sound decision in the selection of these RP-based processes, one must have a clear understanding of the processes and their respective advantages ...

Selective Laser Sintering (SLS)
2004Selective Laser Sintering (SLS) uses a laser beam directed by a computer onto the surface of metallic or non-metallic powders to produce copies of solid or surface models rapidly. It is one of the few RP processes capable of producing durable and functional parts from a wide range of prototype materials that have physical properties similar to ...

Selective laser sintering II. Sintering multilayer refractory composites
Powder Metallurgy and Metal Ceramics, 1998Processes are considered in the selective laser sintering of multilayer composites based on TiN’MTiB2 refractory powder mixtures, hard-alloy material of TN20 type, and a steel substrate. Selectivity of the process, which is expressed in the behavior of the multilayer composite material in sintering regimes that differ in laser power input, is ...

Selective laser sintering in biomedical engineering
Medical & Biological Engineering & Computing, 2012Selective laser sintering (SLS) is a solid freeform fabrication technique, developed by Carl Deckard for his master's thesis at the University of Texas, patented in 1989. SLS manufacturing is a technique that produces physical models through a selective solidification of a variety of fine powders.

Selective Laser Sintering of Metals
Manufacturing Science and Engineering: Volume 2 — Non-Traditional Design and Layered Manufacturing; Rolling Technology; Intelligent Machine Tool Systems; Measurement and Inspection of Products and Processes; Non-Traditional Manufacturing Processes of the 1990s, 1994Abstract The use of Solid Freeform Fabrication for creating models and visual prototypes of products is gaining rapid acceptance in industry as an aid to decreasing time-to-market while increasing product quality. Research in these technologies has now turned to searching for new processes and material systems that will allow the ...
