Analysis of Shape and Dimensional Deformation of the Gear Made by Digital Light Processing (DLP) Additive Technology and Measured by Industrial Tomography

Abstract

Industrial tomography is currently the fastest growing sector of non-destructive research. Until recently, the use of computed tomography in industry has been limited mostly to defects in materials due to lack of accuracy. Modern measuring machines combining metrology and tomography can extract information about the external geometry and volume of the part with high precision from a single scan. This article deals with the transmission gearing scanning, which is a functional component used in the mechanical transmission design. It is imperative that it does not contain internal defects that can largely render the transmission ineffective due to the strain caused by stress. The component is produced by Digital Light Processing (DLP) additive technology. The chosen production method ensures greater strength of the part. The part will be made of material call as „Proto GRY “on a FabPro1000 printer from the company 3D Systems, Inc. The production process of the model will depend on the change in the orientation of the part.
