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.

Preliminary experience with sand casting applications of rapid prototyping by selective laser sintering (SLS)

ICALEO 2000: Proceedings of the Laser Materials Processing Conference, 2000
The layers fabrication technique, known as Selective Laser Sintering SLS, is widely used. A basic investigation on its application in the field of the fabrication of transitory molds in the foundry industry is the object of this work. In fact, the Selective Laser Sintering (SLS) of pre­covered foundry sands allows the aggregation of adjacent particles ...

Systematic Dimensional Calibration Process for 3D Printed Parts in Selective Laser Sintering (SLS)

Volume 1A: 35th Computers and Information in Engineering Conference, 2015
The selective laser sintering (SLS) processes, known for enhancing engineering properties and durability of products, are widely used in auto part development processes. The dimensional displacements of the 3D printed parts, however, hinder utilizing the technology directly to enhance their development process. In general, the SLS process causes curved

Experimental determination of material model of machine parts produced by Selective laser sintering (SLS) technology

Materials Today: Proceedings, 2018
Abstract The machine parts realized by additive production technologies are more and more frequently used as parts of machines. To achieve this an exact design process must be carried out, which in general is possible by numerical analysis. To fulfill correct calculation the material properties must be known.

An Approach to Selective Laser Sintering (SLS) of Pre-Coated Sands for Shell Moulding

1999
The Selective Laser Sintering of pre-coated sands is a promising Rapid Prototyping technique for the construction of sand shells for foundry. In this article, the definition of mathematical simulation concepts and a detailed experimental analysis, performed both with conventional and unconventional techniques, is proposed. In particular, two methods to
