ABSTRACT = {In this study, the Polyamide-12 (PA-12) powdered material in the Selective Laser Sintering (SLS) process has been incorporated as the filler in the composite material to enhance its properties. The PA-12 powder has been made into a form of filament and is primarily used in the Fused Deposition Modelling (FDM) process. The PA-12 has been used with epoxy resin and glass fiber with different proportions. The characterization of materials, including the validation of the presence of PA-12 filler with epoxy, has been evidenced using Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), and Thermogravimetric Analysis (TGA) identification methods. The mechanical characteristics of the 3 wt% PA-12 filled composite material showed increased tensile stress compared to other unfilled and 1 wt% filled materials. The contact angle of the 1 wt% PA-12 filler showed good agreement with improving the hydrophobic characteristics of the composite material. The rate of burning in the Horizontal position showed good results for the overall materials with self-extinguishing behavior. The morphological results of the glass fiber with epoxy and PA-12 filler showed better interference resulting in enhancing the mechanical characteristics than that of without fillers.},
