Rapid prototyping technology and 3d scanning verification. case study

The rapid prototyping technology allows to obtain the physical models of the products in a short time and with minimum costs, which allows the study of the designed product characteristics, before the product to be launched in the execution. Checking the products with complex shape is difficult or even impossible to achieve them with conventional methods. By development of the digital technologies, the 3D scanning becomes more and more performant and more accessible to companies. By the 3D scan may be carrying out checks for complex surfaces with appropriate accuracy in a short time. In this paper the authors present how to obtain a complex part through rapid prototyping using Fused Deposition Modelling technology and verification by 3D scanning technique. It presents a case study for a pump impeller.
