Optimum sintering region for laser sintered nylon-12 [PDF]

open access: yesProceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2011
It is well known that the mechanical properties of laser sintered Nylon-12 improve with increased applied energy. However properties can reach a maximum after which, the application of additional energy can a lead to a decline in part properties.

Development of a radiopaque dental glass for endodontic laser applications

open access: yesJournal of Materials Research and Technology, 2020
The aim of this study was to develop a laser-sinterable and radiopaque glass powder as a potential sealer in endodontic therapy. The hypothesis was that it is possible to dope a SiO2-Na2O-CaO-P2O5–based glass with barium (Ba) and tantalum (Ta) in such a ...

High Speed Sintering – Continuing Research into a New Rapid Manufacturing Process [PDF]

open access: yes, 2006
High Speed Sintering (HSS) is an emerging layer manufacturing technique aiming to break into the lucrative field of Rapid Manufacturing (RM). The process is likened to Selective Laser Sintering (SLS), however, instead of a laser dictating the sintered ...
