This paper explores the measurement and analysis of extrusion forces in the Fused Deposition Modeling (FDM) process, utilizing a custom-built 3D printer designed for high-performance additive manufacturing. A load cell, strategically positioned between the extruder and the hotend, was employed to capture force data during extrusion. The experiments were conducted across various extrusion temperatures (200, 225, 250 °C) and filament feed rates (ranging from 1 to 12 mm/s) to examine the impact of these parameters on the extrusion force. Acrylonitrile Butadiene Styrene (ABS) filament was selected as the material for all experiments due to its widespread use and availability in the industry, making it a standard choice for many FDM applications. The study leverages Klipper firmware for precise control of the printing conditions, ensuring accuracy in the data collected. The findings contribute to a deeper understanding of the extrusion dynamics in FDM, offering valuable insights for optimizing the process and validating numerical models designed to predict extrusion behavior. This research highlights the critical role of force measurement in advancing the capabilities and reliability of additive manufacturing.
