SUNLU Nylon-Like PA Resin 1KG 405nm – Strong Durable Flexible Photopolymer for LCD/DLP/SLA

SUNLU Nylon-Like PA Resin is a strong, durable, and flexible photopolymer that mimics the properties of nylon (polyamide). With excellent tensile strength (20-45 MPa), high elongation at break (20-50%), and superior bending performance, this resin is ideal for parts that need to flex without snapping.
Perfect for functional prototypes, living hinges, snap-fit assemblies, and parts that require a combination of strength and flexibility. Compatible with most LCD, DLP, and SLA printers at 395-405nm.

SUNLU Nylon-Like PA Resin FAQ
Q: Is this resin actually nylon?
A: No, it’s a photopolymer resin formulated to mimic nylon’s flexibility and toughness. It won’t absorb moisture like real nylon and doesn’t require drying before use.
Q: How does Nylon-Like compare to ABS-Like resin?
A: Nylon-Like PA has significantly higher flexibility (20-50% elongation vs 15-25%) and better bending performance, making it ideal for parts that need to flex. ABS-Like is more rigid and better for structural parts that need stiffness.
Q: Do I need to post-cure Nylon-Like resin?
A: Yes, UV post-curing is recommended for full mechanical properties. Over-curing can reduce flexibility, so follow recommended curing times.
Q: Can I use this for parts that flex repeatedly?
A: Yes, the high elongation at break makes this resin suitable for living hinges and parts that undergo repeated bending, though performance will depend on wall thickness and design.
