Computer software plays an important role in the implementation of Solid Freeform
Fabrication (SFF) technologies. This paper describes a software testbed for processing
part geometry for a particular SFF technology, selective laser sintering (SLS), that is built
around the separation of the slicing and rasterization operations to accommodate geometric
information from a variety of sources. The paper also discusses the process control
software being developed for a new high-temperat rkstation for SLS of metal
powders. This program features a high-resolution data rmat, the ability to interpolate
to achieve a desired resolution, and a menu-driven user interface with graphical feedback
and process simulation capabilities.Mechanical Engineerin
