An investigation of geometrical accuracy of desktop 3D printers using CMM

3D printing technology is leading to great advancements and expanding the limits in many engineering fields and education. Geometrical accuracy of the parts produced by 3D printing could be a very important characteristic for some purposes. In this paper the geometrical accuracy of parts produced by FDM (Fused Deposition Modelling) 3D printing technology is investigated. For this purpose a benchmark part is designed and size, form, orientation and location accuracy of different features on it are evaluated using coordinate measuring machine. Two different FDM desktop 3D printers are used for the benchmark part printing.
