Material extrusion(ME) type 3D printing is the most widely spread method among the 3D printing. In the ME type 3D printing, melted filaments are stacked side by side and become a layer. Layers are stacked and become a product. The mechanical property of ME type 3D printed article depends on processing conditions such as nozzle temperature, bed temperature, chamber temperature, nozzle speed, layer thickness, and etc. Different tool path and deposition direction gives different mechanical properties for same processing conditions. The impact strength of ME type 3D printing manufactured specimen has been examined for various tool paths and deposition directions. In some cases, the impact strengths of ME type 3D printing manufactured specimen were higher than that of the bulk material. The impact strengths of ME type 3D printing manufactured specimens strongly depended on tool path and deposition direction.
