Analyzing the effects of FDM printing parameters to minimize the dimensional deviation of polylactic acid Screw and Nut

This article examines the influence of various factors on the precision of ۳D printed objects produced through Fused Filament Fabrication (FFF) using Polylactic Acid (PLA) as the primary material. While PLA is widely chosen for its compatibility with biological applications, it does suffer from limited dimensional accuracy. This study aims to examine the effects of printing parameters, bed temperature, nozzle temperature, nozzle diameter, print speed, infill density, infill angle, and layer height on the dimensional accuracy of a geometrically complex part, such as a screw and nut, along the length, width, and height axes. This analysis seeks to distinguish these parameters' influence on overall and detailed dimensional characteristics.
