Evaluates how thermoplastic polyurethane affects the mechanical properties of PLA and ABS filaments, indicating potential improvements for 3D printing.
Key Points
The aim is to investigate how thermoplastic polyurethane modifies the mechanical and thermal properties of PLA and ABS filaments for enhanced 3D printing.
Polymers blended with TPU at 10–50 wt%
Filaments processed via single-screw extrusion
Tensile specimens fabricated according to ASTM D638 Type I
Tensile strength and elongation measured for five specimens per composition
Thermal properties analyzed using differential scanning calorimetry (DSC)
Incorporating TPU increased ductility and energy absorption in both polymers
ABS/TPU blends showed a 221.4% toughness enhancement at 30 wt% TPU
