Paper Abstract

At the 20th Century 'time compression' is the key word in the automotive industry to aero-space industry to fabricate functional parts. The idea from drawing board to engineering design to form near net shape functional part is the key issue. Photonics has already shown one solution in laser rapid prototyping of low cost, quick tooling of functional parts. At present the choice of materials is limited and the time to get a functional part is almost a week. The conventional rapid prototyping processes do not have just one simple single step. Effectively it has multiple stage of pre- and post-processes. The process developed at the University of Connecticut is extension of the DTM processes. In these new techniques compact, high efficient, low cost diode laser is being used as an energy source and with the development of power delivery systems processing multi- material requires not only average high power, but also high beam intensity or power density. This paper will describe the effects of powder size and laser radiation wavelength of SLS functional parts. The purpose of this study is to rapid product development of functional parts directly from metal powder from room temperature powder bed using diode laser.
