For a given material system, the laser energy density, E s is a key factor which affects quality of the laser sintered structure. A laser energy density is defined by the laser power, laser scan speed and laser beam spot size: $$ {E_s} = \frac{P}{{v\delta }}\left( {J/c{m^2}} \right) $$ (5.1) where P is the incident laser power (Watts), v, the

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 ...
