Abstract
The idea of layer-by-layer deposition of materials to obtain three dimensional shapes, known as three dimensional printing, has gained much popularity during the last decade. Investigations related to understanding the effect of process parameters on the output of the accuracy of parts produced by three dimensional printing processes have been performed by various researchers. This study is also aimed at investigating the effect of deposition speed on the accuracy in terms of geometric dimensions and tolerancing such as flatness and cylindricity of the parts produced by open source three dimensional printers. The repeatability of the parts printed were also investigated.
