What is selective Laser Sintering ?
Solution: Selective laser sintering is rapid prototyping method. It works on the principle that a very thin layer of heat-fusible powder when spread in a container, representing the working space, and heated to just below its melting point by a laser beam, translates the CAD model by sintering the powder, forming a solid layer of the object being constructed. This process is repeated many times, layer-by-layer sintering the powder to the shape of the object. Since the laser beam is only modulated along the geometry of the cross section defined by each layer, the rest of the powder remains loose and can be removed by air when the object is ready. The advantage of the loose powder is that it provides a natural, stable bed for the object to develop until it becomes complete. 10.) Explain Laminated Object Manufacturing? Solution: Laminated Object Manufacturing (LOM) works on the principle that the 2D cross section of the 3D solid or surface model when traced by a laser beam, the layers are
