Rapid Prototyping

The prototyping process is called Selective Laser Sintering. It builds a desired part layer by layer with each thickness of heated powder fusing to the one below until the part is complete.

How Does it Work

• A three dimensional solid computer aided design model is sliced into thin cross sections with up to 250 slices per inch.
• The initial cross-section of the object is traced on the powder bed using a carbon dioxide laser. This fuses it into a solid mass in those areas defined by the object's geometry.
• Another layer of powder is added on the top of the previous layer, and this process is repeated until the part is complete. This takes place within hours.
• On completion of the part, it is removed from the cylinder of loose powder. Light sanding may be necessary, and the part can be painted or used in a secondary tooling process.

History of the Rapid Prototyping Facility

In 1993 the University of Louisville became the first U.S. University to buy and operate the Selective Laser Sintering equipment. It has since been assisting industrial users and engineering programs with this facility.

Users gain access to problem solving technology as well as to continuing research. The University of Louisville's Speed School students and graduates benefit by having access to this state-of-the-art technology.

Getting a quality product quickly is critical and correcting design flaws early is essential. Users have found that the University of Louisville's Rapid Prototyping Facility saves time, money and long delays in product development. The results of this facility are tough, flexible and testable parts for prototypes.
