Selective laser sintering in biomedical engineering

Medical & Biological Engineering & Computing, 2012
Selective 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.

Development of Powders for Selective Laser Sintering

Applied Mechanics and Materials, 2015
The selective laser sintering is a technique used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design CAD data. This technique is used to obtain complex pieces in different domains like machine building industry, automotive industry, foundry and medicine.

Microstructure of selective laser sintered polyamide

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2003
The selective laser sintering (SLS) was used to prepare components from modified polyamide (PA) powder. The behaviour of the sintering process was analyzed. The influences of the fill laser power, powder bed temperature and powder thickness were discussed in detail. By means of SEM, the morphology and the heat influence were analyzed. Results show that

Onset of selective laser flash sintering of AlN

International Journal of Applied Ceramic Technology, 2021
AbstractFlash sintering uses a combination of heating and electric fields to rapidly densify ceramics. Previously, it has been shown that a scanning laser can be used to initiate flash sintering in localized regions on an yttria‐stabilized zirconia (YSZ) sample in a process known as selective laser flash sintering (SLFS).

Evolution of Direct Selective Laser Sintering of Metals

Advanced Materials Research, 2011
Direct Metal Selective Laser Sintering (DMSLS) is a layer-by-layer additive process for metal powders, which allows quick production of complex geometry parts. The aim of this study is to analyse the improvement of DMSLS with “EOSINT M270”, the new laser sintering machine developed by EOS.

Automatic Laser Control System for Selective Laser Sintering

IEEE Transactions on Industrial Informatics, 2019
The 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, 2013
Nowadays, 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
