On the Study of Effect of Coupled Parameters of Fused Deposition Modelling and CO2 Laser Operation for Improved Surface Finish
Abstract. Fused deposition modelling (FDM) is an additive manufacturing (AM)/3D printing process that provides a layer by layer deposition technique to fabricate 3D shapes. FDM technology is being used for printing prototypes and full functional parts. The one of the limitation of FDM process is that it induces a seam between two layers. This seam results in visible rough pattern and these rough patterns affect the surface roughness of FDM built surfaces. Therefore, to ensure desired aesthetic and proper functionality, surface quality of FDM built surfaces must be improved. Literature review reveals that the poor part quality is a major drawback of FDM build parts. These issues have been addressed by a number of researchers. They reported that the improving surface of the prototype is best assessed by post-processing or finishing processes. Subtractive manufacturing processes such as traditional lathes, milling, computer numerically controlled (CNC) machining and abrasive flow machining (AFM) are generally used for post-processing or finishing processes. In the present time, post-processing or finishing approach is becoming more popular post-processing technique.
