Design And Prototype Of Elliptical Trammel Using 3D Printing

Abstract: Additive Manufacturing (AM) is a group of 3D printing techniques aiming design verification, visualization, and kinematic functionality testing. This includes several methods such as selective laser sintering (SLS), fused deposition modelling (FDM), stereolithography (SLA) and three-dimensional printing (3DP). In this paper we use FDM methodology. It is the most common 3D printing method. On the contrary of advantages of FDM method, there are some uncontrollable production problems to be solved such as incomplete bottom layers, hanging strands, missing walls, pillowing, shifted layers, unfinished parts, and delamination of layers, warping syndrome, burn marks and irregular walls. Various three-dimensional printing (3-DP) techniques are available for fabricating parts by offering better quality characteristics regarding materials and performance. In the proposed work, the performance characteristics of the FDM fabricated parts using Polylactic Acid plus known as “PLA plus”.
In this study, FDM process use to print a prototype of Elliptical Trammel. During production problems are investigated and grouped. Also, solution approaches are presented to prevent those production flaws. AM has implemented a novel method of production in design, manufacture, and delivery to end-users. Accordingly, AM technologies have given great flexibility in design for building complex components, highly customized products, effective waste minimization, high material variety, and sustainable products.
