Abstract
The additive manufacturing (AM), also referred to as 3D printing, is a manufacturing process which is characterized by the addition of successive layers of material. One of the AM principles is the material extrusion, where a filament of material, produced by an extrusion nozzle, is deposited following a tool path to fill in all areas of each layer. In the path planning it is defined the deposition strategy and the sequence in which the filament will be deposited. In this principle, it is observed that the extrusion nozzle must stop extrusion and jump from one point to another to start a new deposition. Several studies were done to optimize time building by using optimized path planning algorithms. However, it was not found many works exploring the effects of the tool path optimization in the produced parts. Therefore, this study aims to evaluate the influence of path planning optimization on part dimensional and building time in the material extrusion principle. This study used the Simplify3D program for the path planning, applying optimization algorithms. Samples were fabricated with and without tool path optimization, individually and in sets, using the 3D Cloner printer (material extrusion principle).
