Fused Filament Fabrication is an Additive Manufacturing technology that is continuously improving its technologies. The present research exposes the use of the Travel Salesman Problem and Nearest Neighbor Algorithm as a strategy to reduce the time need to print slots shield in a Printed Circuit Board. The methodology used describes the process from the design to the printing board. A board of 98 slots of four geometries was analyzed. The results present a reduction of 5.88% of the original time required to print the board.
