Experimental Study on Sintering Parameters in Selective Laser Sintering for ABS
Advanced Materials Research, 2011Sintering temperature influences on sintering process essentially. Laser power and scanning speed determined sintering temperature. Preheat to powder is beneficial to improve the surface temperature uniformity. Stress concentration of part is various in different layer depth.

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 ...

A Technological Approach for Selective Laser Sintering
1999Two of the key factors in the densification of powders properties in sintering processes — the green body density and green body strength — are studied with the purpose of giving appropriate empirical modeling of the laser sintering of uncoated metal powders.

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.

Micro Fabrication with Selective Laser Micro Sintering
2006 1st IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2006Silicon-based MEMS techniques are very popular for the manufacture of micro parts. Only a limited number of materials can be processed by these techniques. As the rapid development of Selective Laser Sintering(SLS) in laser rapid prototyping field almost any material can be used.

Powder Densification Maps in Selective Laser Sintering
Advanced Engineering Materials, 2002Selective Laser Sintering (SLS) is a manufacturing process in which a part is produced without the need for part-specific tooling. It competes effectively with other manufacturing processes when part geometry is complex and the production run is not large.

Temperature monitoring in selective laser sintering/melting
SPIE Proceedings, 2010The optical systems for temperature monitoring of SLS/SLM process are developed and integrated with industrial SLS/SLM machines. The system provides the possibility to spatial distribution of brightness temperature at two wavelengths and selected temperature profiles, calculation of colour temperature and express analysis of possible deviations of ...
