Viscous Resin Viscous resin is a thick, high-viscosity photopolymer used in SLA and DLP 3D printing for enhanced layer adhesion, impact resistance, and mechanical properties. It provides excellent toughness, elongation, and chemical resistance. Viscous resins require optimized exposure settings, peeling mechanisms, and resin agitation to prevent layer separation or curing defects. Proper heating, mixing, and degassing ensure consistent flow and polymerization. Advanced formulations offer flexibility, transparency, or biocompatibility. Viscous resin expands applications in engineering, dental models, and functional prototypes requiring high strength and durability. |
