ZR820 High-Transparency Photopolymer Resin is a premium-grade, optically clear SLA 3D printing material engineered for applications demanding exceptional clarity, dimensional accuracy, and balanced mechanical performance. Designed for 355nm stereolithography systems, ZR820 delivers up to 85% light transmittance, making it ideal for lenses, fluidic devices, lighting components, and visual prototypes requiring optical-grade transparency.
With low viscosity (190 CPS), ZR820 ensures smooth resin flow and fast layer adhesion — perfect for high-resolution prints with fine details. After full UV post-curing, it achieves enhanced mechanical properties: flexural modulus up to 2340 MPa, impact strength up to 55 J/m, and hardness of 79 Shore D, while maintaining excellent elongation (10–15%) for toughness without brittleness.
Key Advantages:
- Ultra-high transparency (up to 85%) for optical & visual applications
- Low viscosity (190 CPS) enables faster printing and finer detail resolution
- Balanced stiffness and toughness after post-cure
- Compatible with most 355nm SLA/DLP printers
- Minimal yellowing or haze after curing — maintains crystal-clear finish
Technical Specs Summary:
- Liquid State: Light purple transparent liquid, 1.10 g/cm³ density, 190 CPS viscosity @25°C
- Cured Properties (Post-Cured): Up to 2340 MPa flexural modulus, 62 MPa strength, 55 J/m impact, 79 hardness, 15% elongation
Forgecise ZR820 High-Transparency Photopolymer Resin is ideal for engineers, designers, and manufacturers in medical device development, consumer electronics, automotive lighting, jewelry casting masters, and academic research labs seeking reliable, high-clarity photopolymers for precision additive manufacturing.
