Characterisation of innovative materials for Direct Laser Sintering
MRS Proceedings, 2004ABSTRACTThe performances achieved by Rapid Prototyping techniques are progressively leading towards Rapid Manufacturing, that is the capability to produce end products, directly from the CAD model. Even so, the diffusion of these techniques is hardly supported by scientific knowledge about the micro-mechanisms ruling the macroscopic performances of the

Over the last decade, several RP methods have been developed as techniques to directly or indirectly fabricate ceramic parts. Each process has its own characteristics, advantages and disadvantages. To make a sound decision in the selection of these RP-based processes, one must have a clear understanding of the processes and their respective advantages ...

The Selective Laser Sintering of Polycarbonate
CIRP Annals, 1996Abstract This paper investigates thermal modelling of the selective laser sintering process for amorphous polycarbonate powders. The aim is to develop a simulation for process accuracy and control which are key areas of developement for the new layer manufacturing rapid prototyping technologies.

Selective laser sintering in biomedical engineering
Medical & Biological Engineering & Computing, 2012Selective 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.

Laser‐Sintered Barium Titanate
Journal of the American Ceramic Society, 1989Laser sintering of alkoxy‐derived ultrafine BaTiO 3 powders was investigated. The temperature increases of the sample with laser irradiation were measured with a thermocouple. It was found that laser irradiation could generate enough heat to sinter ceramics. A slurry was prepared by mixing an

Laser sintering of LDS material
2016 12th International Congress Molded Interconnect Devices (MID), 2016Since additive manufacturing process can provide plastic parts with more complexity than injection molding, MID process starting from AM process, instead of molding, has a great potential to improve shape complexity of MIDs. In this research, laser sintering of LDS compatible material was tested.

Industrial laser micro sintering
ICALEO 2004: 23rd International Congress on Laser Materials Processing and Laser Microfabrication, 2004As mechanical engineering industry encounters a growing demand of µm-sized or µm-structured components for an increasing range of applications, miniaturization is presently ranking among the most important goals in product and tool development. Compared to still higher resolving techniques, selective laser sintering (SLS) still bears the

Selective Laser Sintering of PEEK
CIRP Annals, 2007Abstract Polyetheretherketone (PEEK) is a good choice especially for manufacturing medical instruments or implants. These parts are typically produced by conventional manufacturing methods, like injection moulding. Selective Laser Sintering (SLS) could offer more flexibility.
