Mechanical properties, morphology and chemical interactions of 3D printed polylactic acid/bio-based polyurethane blends

Key Points

• Mechanical properties correlate strongly with chemical interactions, indicating enhanced material strength.
• Key findings show that blending polylactic acid with bio-based polyurethane results in a 25% increase in tensile strength.
• Analysis of blends was performed using a combination of 3D printing techniques and mechanical testing methods.
• These findings may enable further development of biocompatible materials for sustainable manufacturing.
