This paper describes Research & Development of new Laser Sintering apparatus for producing Micro Mechanical Parts. Laser Sintering Technology is well known as one of Rapid Prototyping Technologies. This technology is commonly applied for producing functional parts such as intake manifolds and propellers in industries like Automotive and Heavy industry. However, Laser Sintering Technology has not been widely adopted in Computer & Home Appliance industries. This is due to technical limitations, which has made it difficult to produce parts with small features. (Thin walls or ribs below 0.5mm thickness.) In this project we developed a new Laser Sintering Apparatus (SEMplice 300) capable of producing micro mechanical parts, based on our feasibility study of smaller beam diameter, smaller layer thickness, and smaller powder size.
