Investigating the influence of print settings on PLA filament using the Espresso F220 3D printer / Ani Amanina Anuar ... [et al.]

This research focuses on optimizing the 3D printing settings of the Espresso F220 3D printer using Polylactic Acid (PLA) filament. A user-friendly guideline was developed to assist users in identifying critical model sections requiring support structures to prevent printing defects and adjusting retraction settings to minimize stringing. The Support Structure Test (SST), Retraction Test (RT) and Tensile Test (TT) profile setting were evaluated. Results SST the effectiveness of support structure at various angles, where the RT to produce the optimal retraction distance to reduce stringing between towers. In TT investigated the effects of printing temperature (190°C, 210°C, and 230°C) on mechanical strength of PLA material. Model 4, utilizing setting from previous studies, proven the best quality prints with minimal surface damage. TT results proven the higher printing temperature resulted in the strongest PLA material, and suitable for many applications. The research offers valuable insight for optimizing FDM in 3D printing process in engineering applications at UiTM Penang.
