DESIGN AND DEVELOPMENT OF A FUSED DEPOSITION MODELLING RAPID PROTOTYPING MACHINE

Abstract

Rapid Prototyping is an additive manufacturing process by which a Three-Dimensional Model is made by various processes like SLA (Stereolithography), SLS (Selective Laser Sintering), LOM (Laminated Object Manufacturing), etc. A 3d printer which uses FDM (Fused deposition modelling) process is a 4-axis machine, in which 3 axes are x, y, z axis and fourth axis is the extruder, with which a filament comes out to form a layer. This paper emphasizes on design and development of a rapid prototyping machine which refers to a process of FDM (Fused Deposition Modelling), where a material like PLA (Polylactic acid), ABS (Acrylonitrile Butadiene Styrene), PC (Polycarbonate), etc., is heated to its melting point and is deposited layer by layer. Many such layers are fused to form the final 3d model.
