From the dawn of human existence materials have been fundamental to the development of civilization. Anthropologists define the historical epochs by the materials used by the different civilizations such as the Stone, Copper, Bronze and Iron ages. The different rates of progression towards more sophisticated materials between cultural groups correlated with different levels of innovation and the local availability of those materials, and led to varying standards of living.
Materials science and technology is a multidisciplinary approach to science that involves designing, choosing, and using three major classes of materials—metals, ceramics, and polymers. Materials science combines many areas of science (chemistry, physics, and engineering) to make better, more useful, and more economical and efficient “stuff”.
Selective laser melting (SLM) is one of the newly developed additive manufacturing (AM) processes by which a product is built by melting selected areas of powder layers under a protective atmosphere, using a computer controlled laser beam. In the process, a high intensity laser beam selectively scans a powder bed, melting the particles which solidify to form a solid layer. A new layer of powder is deposited on top of the previously formed solid layer and the process continues until the part is complete.
The presentation focuses on Selective Laser melting technology.
