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.

Material properties and selection for selective laser sintering process
International Journal of Manufacturing Technology and Management, 2013Nowadays, to produce better quality products with less cost, shorter lead times, more customer delights have become the key requirements to remain competitive in the global market. To fulfil these requirements, additive manufacturing (AM) provides a technological tool for making solid free form products. Selective laser sintering (SLS) is one of the AM

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 of patch antennas on FR4
2005 IEEE Antennas and Propagation Society International Symposium, 2005The paper investigates the fabrication of microwave components using selective laser sintering (SLS) on FR4. This technique has exciting potential for the metallization of low-temperature substrates. The effects of the laser process parameters on the DC conductivity are examined. These results are applied to produce a patch antenna which is compared to

Effective process parameters in selective laser sintering
International Journal of Rapid Manufacturing, 2014Selective laser sintering (SLS) is a powder–based rapid prototyping (RP) technology in which parts is built by CO2 laser. This research work presents an optimal method to determine the best processing parameter for SLS in order to fabricate parts with enhanced component integrity and reduced overall costs using stainless steel material.
