Preliminary investigations on performance of acetone vapour jet drilling operations on 3d printed abs parts

Abstract

Since the debut of 3D printing, industries have seen an exponential increase in output and efficiency. 3D printing is an Additive Manufacturing (AM) approach that challenges the traditional method of manufacturing and finishing. The underlying idea of AM is layer–on–layer deposition. In traditional procedures, the materials are subjected to a number of damages as a result of the tool-workpiece contact, which causes friction and heat dissipation. The use of 3D printing to overcome the traditional way of machining is a new innovation in the industries. Non-traditional approaches are further adopted for post processing of 3D printed manufactured parts. In the present study, influence of Acetone Vapour jet drilling process on Acrylonitrile butadiene styrene substrates have been investigated in order to identify range of parameters i.e. pressure of jet, flow rate and distance between workpiece and nozzle, which have significant impact on output responses viz. surface roughness and circularity. After successful experimentation it has been found that pressure 3 to 5 bar,flow rate 13 to 19 ml/min and standoff distance 1.5 to 3.5 mm range are the most impactful range of parameters.
