ABSTRACT
This paper presents the process manufacturing a two-stroke internal combustion engine block prototype, including the additive manufacturing process of the molds. For this purpose, an engine block that can be manufactured with the additive manufacturing equipment was selected. Later, silicone rubber molds will be obtained from the plastic patterns whose function is to behave like matrix to obtain replicas in wax of the motor block. Finally the appropriate casting method was selected, after experimenting with several processes the engine block was fabricated with vacuum assisted casting. The numerical simulation of the casting process for this project was a great help in predicting defects during casting. Elements such as the riser was located appropriately in the motor block to absorb the greatest amount of porosity.
