Abstract

Rapid Prototyping is an Additive Manufacturing process used for creating objects that are inconvenient or expensive to manufacture by conventional machining processes. Considering its growing popularity in today’s world, it becomes necessary to quantify this technology in order to give its users a clear picture about how beneficial Rapid Prototyping could be if it were made commonly available at cheaper rates. One of the most useful manufacturing technologies existing today, Rapid Prototyping helps in the creation of miniature prototypes of large machines and structures, medical equipment, and even art forms. There are several different forms of this technology which employ different methods and different materials to print 3 Dimensional solid objects. [1] This creates a dilemma to the user, as he has to make a choice between these forms of Rapid Prototyping in order to use it for his needs. This paper emphasizes on the qualitative testing of identical specimens created by two of the most popular Rapid Prototyping processes available today, namely Stereolithography (SLA) and Selective Laser Sintering (SLS). The specimens will be evaluated on the parameters of Dimensional Accuracy, Tensile Strength, Water Absorption, Shore Hardness, Surface Roughness, Density and Microscopic Defect Structure. The outcome of this study aims at helping people to understand SLS and SLA better in terms of the products they create, so that it becomes easier for users to make a choice between the two. It also aims at highlighting the above mentioned statistical information about SLA and SLS so that they may be improvised and enhanced in the future
