Research on improving the accuracy of FDM 3D printing process by using a new designed calibrating part

The article presents theoretical and experimental research methods that were used at the Technical University of Cluj-Napoca (TUCN) to improve the accuracy of Fused Deposition Modeling (FDM) 3D printing process. Finite element analysis method was successfully used for estimating the shrinkages of an original calibrating part that has been originally conceived for this purpose, this part being finally made using an original software application and FDM 3D printing equipment at TUC-N
