Sažetak
The term Rapid Prototyping means creating a physical prototype or the basic model from which would later emerge newer models and finally the final product. Over time, the term Rapid Prototyping is replaced by term Additive Manufacturing. The higher quality of workpieces and similarity to finished products lead to pieces which can be used, immediately after the completion, in practical applications, or can completely replace products made by traditional technological processes. Unlike traditional technological processes of removing material (turning, milling, drilling, etc.) in these processes all the parts are made by applying material in layers. Each applied layer is a thin cross section of a model generated in some of the software for 3D modelling. Because in the real world each deposited layer has a certain thickness, the resulting worpiece will be an approximation of original model. Today, on the market, there are several additive manufacturing processes. These processes differ according to the type of material used for making pieces and according to the manner in which the layers of material are applied and joined together. These differences affect on dimensional accuracy of workpiece, mechanical properties, surface roughness, speed of technological process, necessity of postprocessing and the overall costs associated with the machine and technological process. In this paper will be shown production of CAD 3D model with three different additive manufacturing processes: 3D printing, Fused Deposition Modelling and Selective Laser Sintering. The objective of this work is to choose one of these three processes that is most suitable for practical application. According to this, there are defined certain criteria and AHP method is used for making decision.
