Comparing the Geometrical Accuracy of a 3D Printed Pattern to a Metal Pattern

Abstract

Rapid prototyping is a new field where the depths are still being analysed, this paper is in regards for applying the subject to the field of pattern making.The work also extends to the area of comparing the low cost rapid prototyping to that of a pattern producedby CNC in terms of the geometrical accuracy so as to check the usage of the 3Dprinting in the field of pattern making. Possible foreseen actions that could benefit the pattern making industry are that of cost reduction and the time to produce a work piece. The scope of the paper lies in terms of the accuracy and the surface roughness since these affect the quality of the product to be produced. Since the dimensional accuracy is an important factor while pattern making is used, critical dimension which including the taper at a lower distance and some angle is also used so that the best results would be obtained. The dimensions are also checked by using a coordinate measuring machine, vernier callipers and machine vision. Machine vision has been applied so as to check whether they provide a scope for replacement of the conventional technique of quality inspection in the pattern making industry.
