Comparative Measurement of Cylindricity of Models Manufactured Using FDM Technology
摘要
Fused deposition modeling (FDM) is one of the most popular additive manufacturing (MEX) processes. Due to the low cost of 3D printers and building material, this technology can be used to produce fully functional mechanical parts, including cylindrical elements. Form deviations and especially cylindricity deviations should be measured to fully determine the accuracy of the printed parts. This type measurement makes it possible to identify possible defects resulting from the 3D printing process. The paper presents the results of measurements of form deviation (cylindricity) of cylindrical elements made with the use of ABS material by Fused Deposition Modeling. Three series of samples of 10 each were made. These samples were made taking into angles three different printing orientations, i.e. 0°, 45°, 90°. For comparative analysis, the cylindricity deviation of the printed samples was investigated using two measuring systems. The first measurement system treated as a reference system was the Talyrond 365 using the radius-change method. The second measurement system used for the tests was the Prismo Navigator coordinate measuring machine from Zeiss. The results of the research presented in the article showed that the printing direction has a significant impact on the values of cylindrical deviation of models made with FDM technology. In addition, the printing direction also had an impact on the differences between the deviation values obtained using the two measurement systems. However, it can be considered that coordinate measuring technology can be successfully used to evaluate the cylindricity of FDM components.
