Abstract
The purpose of this paper is to present a new 3D printing method called Selective Laser Baking (SLB) to fabricate 3D parts with Poly Vinyl Chloride (PVC) material. The Mid Power Lasers are used at the SLB method for heating and shaping to PVC layers by laser scanning on the surface of the PVC compound. After designing a 3d model on the computer, transforming it into two-dimensional(2D) layers on common software, and controlling the laser scanning system by a computer, the pattern of each layer is constructed on the surface of PVC compound and layers are sequentially built on each other until a 3D part is made from PVC material. The most common method for producing PVC parts is molding. Fabrication of Customized PVC parts is always a challenge. 3D printing can be used to overcome this drawback. Despite the existence of a simple material extrusion 3D printing technique, this technique does not provide acceptable resolution and lead time.
