The Selective Laser Sintering of Polycarbonate
CIRP Annals, 1996Abstract This paper investigates thermal modelling of the selective laser sintering process for amorphous polycarbonate powders. The aim is to develop a simulation for process accuracy and control which are key areas of developement for the new layer manufacturing rapid prototyping technologies.

Selective Laser Sintering of PEEK
CIRP Annals, 2007Abstract Polyetheretherketone (PEEK) is a good choice especially for manufacturing medical instruments or implants. These parts are typically produced by conventional manufacturing methods, like injection moulding. Selective Laser Sintering (SLS) could offer more flexibility.

Selective Laser Sintering of Zirconia
MRS Proceedings, 2000AbstractA combination of Selective Laser Sintering and colloidal infiltration has been used to create partially stabilized zirconia molds for titanium casting. The mold material system was chosen for its low reactivity with molten titanium and thermal shock resistance.

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

Composite Micropowders for Selective Laser Sintering
Metallurgist, 2016A method is proposed for obtaining composite micropowders. The technology includes the atomization of liquid metal by a gas jet and modification of the micropowder in a planetary mixer in the presence of carbon nanopowder. The particles of the composite micropowders produced by this method are close to spherical in shape.

Selective laser sintering of compacted powders
Powder Metallurgy and Metal Ceramics, 1998The selective laser sintering of preliminarily compacted powders was investigated. Depths of sintering lower than those with freely poured powders were attained. This has a negative effect on the production of multilayered articles. The main disadvantage of the process, however, was the difficulty in separating the article from the unsintered compacted

Selective laser sintering of microwave components
2005 European Microwave Conference, 2005This paper investigates the fabrication of functional microwave components using the selective laser sintering process to sinter conventional screen printing inks. This technique has the potential to metallize low-temperature substrates by controlling the laser parameters.

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 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.
