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.

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

Automatic Laser Control System for Selective Laser Sintering
IEEE Transactions on Industrial Informatics, 2019The quality of SLS products is dramatically degraded by excessive temperature gradients in the thermal profile of the powder bed. Thermal gradients in the presintering temperature, which is defined as powder temperature before laser scans, are inevitable in commercial SLS machines due to various reasons.

Investigations on laser sintering of ceramic slurries
Production Engineering, 2007For almost two decades, layer manufacturing techniques have assisted the product development at various stages from the operational point of view. Laser sintering is a powder-based layer manufacturing technology. Since the beginning of the 1990s, laser sintering of ceramic materials has been investigated academically.
