        abstract = {This paper investigates the influence of thermal post-processing, specifically annealing, on the mechanical and morphological behavior of ASA (Acrylonitrile Styrene Acrylate) and PET-G (Polyethylene Terephthalate Glycol) 3D printed specimens fabricated through Fused Filament Fabrication (FFF). Mechanical tests including tensile strength evaluations and morphological analysis via Scanning Electron Microscopy (SEM) were conducted to assess the impact of heat treatment. The study reveals that thermal post-processing enhances inter-layer bonding, reduces porosity, and improves tensile strength and ductility in both materials. Comparative analysis shows PET-G demonstrates greater ductility improvements, while ASA exhibits superior dimensional stability and strength retention under thermal conditioning. These results establish a foundation for optimizing post-processing parameters to improve performance and reliability of 3D printed polymer components.},
