Thermoset meets Thermoplastic: Upcycling PLA in Digital Light Processing 3D Printing of Dynamic Thiol-Ene Composites

Key Points

• To develop a dynamic thiol-ene resin enhanced with micro-sized PLA particles for 3D printing.
• Formulated a dynamic thiol-ene resin suitable for vat photopolymerisation 3D printing.
• Incorporated micro-sized PLA particles into the resin.
• Evaluated the mechanical properties and processing capabilities of the final composite.
• The addition of PLA particles significantly improved the mechanical strength of the composites.
• Dynamic thiol-ene resins exhibited enhanced processability during 3D printing.
• The composites demonstrated promising sustainability characteristics through the upcycling of PLA.
