Homogeneity aspects in selective laser sintering (SLS)

Journal of Materials Processing Technology, 2006
Abstract A measure of powder layer heterogeneity has been proposed. It has been tested on the layers realized by different deposition techniques. Good correspondence of the actual measure to the subjective layer quality estimation has been shown. The influence of the laser scanning strategy on the quality of sintered structure has been examined.

Parameter Optimization for Biocompatible Polyamide Used in Selective Laser Sintering (SLS)

2020
One of the major issues in additive manufacturing concerns the geometrical and mechanical properties of its products. Selective laser sintering uses a laser beam that binds together the biocompatible polyamide powder, having as results rigid parts that can be used for mechanical constructions. The biocompatibility of the material makes the construction

Selective Laser Sintering (SLS)

2004
Selective Laser Sintering (SLS) uses a laser beam directed by a computer onto the surface of metallic or non-metallic powders to produce copies of solid or surface models rapidly. It is one of the few RP processes capable of producing durable and functional parts from a wide range of prototype materials that have physical properties similar to ...

Sintering quality and parameters optimization of sisal fiber/PES composite fabricated by selective laser sintering (SLS)

Journal of Thermoplastic Composite Materials, 2020
This article aims to improve the sintering quality of the sisal fiber/poly-(ether sulfone) (PES) composite (SFPC) part fabricated via selective laser sintering (SLS). The sisal fiber and PES powders were proposed as the feedstock of the SFPC powder bed for SLS.

Fractal scanning path generation and control system for selective laser sintering (SLS)

International Journal of Machine Tools and Manufacture, 2003
Abstract A fractal scanning path which is a FASS (space-filling, self-avoiding, simple and self-similar) curve is proposed for selective laser sintering (SLS). The authors’ preliminary research has proved that the samples which are produced by SLS along a fractal scanning path possess improved physical performance.
