Effects of printing parameters on the mechanical characteristics and mathematical modeling of FDM-printed PETG

3D printing technology has revolutionized free-form construction and customization demand through its ease of use, fast production, accurate, regulated deposition, and flexibility with soft functional materials. Fused deposition modeling (FDM) is an ideal technique for the 3D printing of plastics. T...
