Lasers and materials in selective laser sintering
Assembly Automation, 2003 Selective laser sintering (SLS) is one of the most rapidly growing rapid prototyping techniques (RPT). This is mainly due to its suitability to process almost any material: polymers, metals, ceramics (including foundry sand) and many types of composites.

Influence of the Origin of Polyamide 12 Powder on the Laser Sintering Process and Laser Sintered Parts [PDF]
Applied Sciences, 2017 Different features of polymer powders influence the process of laser sintering (LS) and the properties of LS-parts to a great extent. This study investigates important aspects of the “powder/process/part”-property relationships by comparing two polyamide 12 (PA12) powders commercially available for LS, with pronounced powder characteristic differences (

Laser hardening of steel sintered parts [PDF]
2017 IEEE 3rd International Forum on Research and Technologies for Society and Industry (RTSI), 2017 The possibility of applying rapid and localized laser hardening to near-net shape parts, like the ones deriving from powder metallurgy (P/M) is investigated, demonstrating that even low alloyed steels (Fe + 2% Cu + 0,7% C) can be successfully heat treated with minimal or no dimensional variations.

Oriented texture of Y-doped La10Si6O27 Ceramic prepared by rapid solidification method
International Journal of Electrochemical Science, 2016 Oriented texture La9.33Y0.67Si6O27 ceramic was successfully synthesized by laser rapid solidification method. The La9.33Y0.67Si6O27 crystal was formed only after Yttrium was added into the La10Si6O27 ceramic under the sintering of CO2 continuous wave ...
