The Application of an Artificial Body Force to the Selective Laser Sintering Process
An artificial body force generated by a magnetic field is applied to the green powder bed of a ferromagnetic powder during the Selective Laser Sintering process. Preliminary experiments and theory are formed to determine ...
Direct Selective Laser Sintering of High Temperature Materials
Selective Laser Sintering (SLS) involving a coexisting liquid and particulate solid during the SLS processing can be used to produce freeform parts directly with high temperature materials. Factors such as scanning laser ...
A Method to Generate Exact Contour Files for Solid Freeform Fabrication
Existing methods to create contour files generate a polygonal approximation of the contours instead of an exact representation. This paper presents a method to generate exact contours from Constructive Solid Geometry ...
Laser Tracking Control Implementation for SFF Applications
From a three-dimensional computer graphic model, Solid Freeform Fabrication produces solid objects directly without special tooling and human handling. In order to increas process productivity and accuracy, a time-efficient ...
Process Control System for a High Temperature Workstation performing the Selective Laser Sintering Process
Thispaper describes the design and implementation ofa Computer Process Control System for a High Temperature Workstation performing Selective Laser Sintering of metal and .ceramic powders. As compared to our previous machine ...
Machine Issues Associated with Solid Freeform Fabrication
Before we begin a discussion of machine issues it is important that we categorize exactly what we mean. There are differences between the design of a research piece of equipment as compared to a commercial piece of ...
Application of Factorial Design in Selective Laser Sintering
Selective Laser Sintering (SLS) is a complex process involving many process parameters. These parameters are not all independent. A factorial design technique is utilized to study the effects of three main process ...
