This study investigates the fabrication of composite material based on a Polyethylene Terephthalate Glycol (PETG) matrix reinforced with copper (Cu) particles to fabricate 3D-printed filaments for Fused Deposition Modeling (FDM). The objective is to produce biomedical components with antibacterial properties. Copper particles are incorporated into the PETG matrix at weight fractions of 5%, 10%, 30%, and 50%, then the mixture is extruded in form of composite filaments with an average diameter of approximately 1.75 mm. The polymer-copper composite filaments are subsequently utilized in the FDM process to fabricate biomedical parts. The characteristics of printed specimens are tested by scanning electron microscopy (SEM), tensile strength testing, differential scanning calorimetry (DSC), and antibacterial performance evaluation. The results provide insights into the composite’s properties and its potential applicability in the fabrication of biomedical components by FDM-based 3D printing technology.

摘要

This study investigates the fabrication of composite material based on a Polyethylene Terephthalate Glycol (PETG) matrix reinforced with copper (Cu) particles to fabricate 3D-printed filaments for Fused Deposition Modeling (FDM). The objective is to produce biomedical components with antibacterial properties. Copper particles are incorporated into the PETG matrix at weight fractions of 5%, 10%, 30%, and 50%, then the mixture is extruded in form of composite filaments with an average diameter of approximately 1.75 mm. The polymer-copper composite filaments are subsequently utilized in the FDM process to fabricate biomedical parts. The characteristics of printed specimens are tested by scanning electron microscopy (SEM), tensile strength testing, differential scanning calorimetry (DSC), and antibacterial performance evaluation. The results provide insights into the composite’s properties and its potential applicability in the fabrication of biomedical components by FDM-based 3D printing technology.
