Author Information

Primary Institution: The University of Texas at El Paso
Hypothesis
Can the addition of thermoplastic elastomer improve the properties of upcycled PET for additive manufacturing?
Conclusion
The study demonstrates that upcycled PET combined with SEBS can be used for 3D printing and exhibits shape memory properties.
Supporting Evidence
- Adding SEBS to PET did not significantly change mechanical performance.
- Shape memory properties were quantified for the PET/20% SEBS blend.
- Annealing improved mixing between PET and SEBS, reducing nodules.
Takeaway
This study shows how we can turn old plastic bottles into new materials for 3D printing that can remember their shape.
Methodology
The study involved creating blends of upcycled PET and SEBS, followed by testing their mechanical and shape memory properties through various analyses.
Potential Biases
Potential bias in results due to the limited range of elastomer content tested.
Limitations
The study faced challenges with delamination in tensile specimens and variability in mechanical properties due to printing defects.
