Abstract |
This study proposes the optimum printing conditions for 3D printing to the thickness set by the slice program using FDM-type 3D printer. It can be seen that both the PLA and the ABS filaments have a flow rate of 110% which is closest to the set layer height of 0.2mm. For PLA cubes, the flow rate closest to the volume of 1000mm3 when the horizontal×length×height is set to 10mm each is 90%, and the flow rate closest to the volume of 8000mm3 when the horizontal×length×height is set to 20mm each is 90%. For ABS cubes, the flow rate closest to the volume of 1000mm3 when the horizontal×length×height is set at 10mm each is 80% and the flow rate closest to the volume of 8000mm3 when the horizontal×length×height is set at 20mm each is 80%. From the results of additive microstructure between layers of the PLA cube, the average thickness of a layer is approximately 185 m(=0.185mm) when μ width×length×height is set at 10mm and 20mm respectively. The end parts of the layer of the PLA cube are regularly rounded. The average thickness of a layer of the ABS cube is the same as that of the PLA cube. The end parts of the layer of the ABS cube are thickly rounded, and the other is thinly rounded. |
