The eSUN Standard Transparent Resin (1kg) is a high-precision, 405nm UV-curable photopolymer resin formulated for MSLA/LCD and DLP 3D printers to produce crystal-clear, high-translucency parts. Engineered for low volumetric shrinkage, fast curing, and high optical clarity, this resin delivers smooth glass-like surfaces, sharp geometric details, and excellent light transmission, making it ideal for fluid dynamics models, clear optical enclosures, lighting prototypes, and artistic transparent sculptures.

Features

• High Optical Clarity & Translucency: Formulated with specialized non-yellowing transparent monomers to produce parts with clean light transmission and a glass-like finish when properly post-processed.
• Sharp Feature Reproduction: Delivers crisp fine lines, smooth internal channels, and accurate tolerances without excessive light bleed, ensuring high detail preservation.
• Fast Layer Exposure: High-reactivity photoinitiator package allows short exposure times (1.5s – 2.5s on monochrome LCD screens), reducing total print time while maintaining solid layer cohesion.
• Low Viscosity for Clean Washing: Flows easily across the release film for consistent layer replenishment and rinses off effortlessly in alcohol baths without leaving a sticky film.
• Balanced Rigidity & Toughness: Cures to a sturdy 80D–84D Shore hardness with sufficient resilience to resist cracking during support detachment and assembly.
• Low Odor Formulation: High-purity chemical composition minimizes volatile organic vapors for a cleaner and more comfortable indoor printing environment.

Common Applications

• Optical Housings & Light Guides: Fabricating transparent lenses, LED diffusers, light pipes, illuminated bezels, and display covers.
• Fluid Dynamics & Microfluidics: Printing clear flow manifolds, valve housings, liquid chambers, and internal visual inspection channels.
• Transparent Prototypes & Concept Mockups: Rapid validation of internal mechanisms, see-through product enclosures, and translucent assemblies.
• Artistic Sculptures & Decorative Craft: Creating clear crystal figurines, resin jewels, anime effects pieces, and glass-style ornamental models.

Professional Printing and Post-Processing Tips

• Gentle Mixing Before Use: Gently swirl or roll the bottle before pouring to avoid introducing excessive micro-bubbles into clear resin, which can show as cloudiness in finished prints.
• Baseline Slicer Exposure Settings (Monochrome LCD): Set Bottom / Base Layer Exposure to 25s–35s (5–6 layers) for reliable bed adhesion, and Normal Layer Exposure to 1.8s–2.5s at a 0.05mm layer height (fine-tune using an exposure test chip).
• Clean Washing Cycle: Wash parts in clean 95%+ Isopropyl Alcohol (IPA) or Ethanol for 2 to 3 minutes. Avoid leaving clear parts soaking in dirty alcohol baths to prevent surface haze and white residue.
• Avoid Over-Curing to Prevent Yellowing: Post-cure in a 405nm UV station for a brief 1 to 3 minutes; excessive UV exposure can induce slight yellowing in transparent polymers.
• Technique for Maximum Glass-Like Transparency: To achieve peak clarity, apply a thin coat of clear UV-resistant polyurethane gloss spray, clear epoxy resin, or polish with fine polishing compound after curing.
• Storage & Handling: Always wear nitrile gloves and safety glasses. Store tightly capped in a cool, dark environment away from ambient UV and sunlight (recommended storage temperature: 15°C to 30°C).
