Abstract:
This research aims to determine optimal parameters for the Fused Deposition Modeling--FDM process to reduce the dimensional tolerance of ABS parts within the specified tolerance range. The parameters considered include layer thickness, print speed, and wall thickness. The experimental design was then performed using the Central Composite Design method, with response values collected by measuring the dimensions of the study parts using a Vernier caliper. The results from setting the printing process parameters are a layer thickness of 0.3485 mm, a printing speed of 20 mm/s, and a wall thickness of 2.4949 mm. After completing the print, the printer should be rested for at least 10 minutes. This results in the dimensions of the case study parts falling within the specified tolerance.
