OPTIMISATION OF RAPID PROTOTYPING PROCESS FOR ELECTRICAL VEHICLE MANUFACTURING.

In the case of three-dimensional (3D) printing complex products or big assemblies must be minimize the manufacturing process cost. Taking this into account, some printing parameters must be optimised, such as 3D printing time, post-processing time and material consumption. In this paper, a methodology regarding of design for additive technologies (DFAdT) and design for rapid prototyping/ rapid manufacturing assembly (DFA-RP/RM) is proposed, based mainly on separation of complex products in optimal subassemblies. A case study focused on a new concept of an electric vehicle (self-balancing scooter) is presented. The scaled prototype is manufactured using polyjet additive technology within the Industrial Innovative Technologies Laboratory, Department of Manufacturing Engineering from "Transilvania" University of Brasov, Romania.
