Experimental study aiming to enhance the surface finish of fused deposition modeled parts

In this paper the authors study the influence of FDM machining parameters on acrylonitrile butadiene styrene (ABS) prototypes surface finish. The surface finish of products after the modification of extrusion parameters has been measured and processed through designed experiments. The chemical post-treatment does not require human intervention and has led to a significant improvement in surface finish at the expense of a negligible change in the prototype size.
