Research regarding the design and manufacturing of hand orthosis by using Fused Deposition Modeling technology

The article presents the designing of an orthosis used for immobilization of the hand after a surgical operation or bone fracture. Finite element analysis was used for the shape optimization of the orthosis, in close connection with constrains given by the mechanical resistance of the part and constrains given by the technological parameters used in the AM process. The orthosis was finally manufactured by Fused Deposition Modeling at the Technical University of Cluj-Napoca, the results could be implemented in the Romanian medical system

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
