## Summary description

eSun Hard Tough Grey is a 1 kg UV/LCD 3D printing resin formulated for 405 nm curing. Designed for SLA and DLP printers, this hard and tough grey resin provides durable parts with fine detail and good dimensional stability. Suitable for functional prototypes, mechanical components, fixtures and models requiring higher strength and resistance to wear.

## Long description

eSun Hard Tough Grey is a 1 kg UV/LCD 3D printing resin formulated for 405 nm curing and intended for SLA and DLP printers. The material produces hard, impact-resistant parts in a neutral grey shade, combining fine surface detail with improved mechanical strength and dimensional stability. It is specifically developed for applications that require durable printed components with consistent curing behavior on 405 nm light sources.
Advantages
This hard tough grey resin delivers a balance of rigidity and toughness that reduces brittleness compared with standard brittle resins while maintaining high surface resolution. The formulation offers reliable layer adhesion and low warping for stable prints, and the neutral grey color helps reveal surface detail and post-processing marks. Curing at 405 nm ensures compatibility with a wide range of SLA and DLP machines that use common UV/LCD light sources.
Suitable for
 Functional prototypes and validation models
 Mechanical components, gears and fixtures
 Jigs, tooling and assembly aids
 Small production runs and durable demonstrators
Key specifications
 Weight: 1 kg container of liquid resin
 Photocuring wavelength: optimized for 405 nm UV/LCD light
 Color: neutral grey
 Mechanical properties: formulated for increased hardness and toughness compared with standard rigid resins
 Compatibility: designed for SLA and DLP resin printers using 405 nm light sources
 Surface finish: capable of producing fine detail and smooth surfaces suitable for secondary finishing
How to use
Install the resin in a compatible SLA or DLP printer that operates at 405 nm and follow the printer manufacturer’s guidelines for fill, level and exposure settings. Use recommended exposure and lift parameters for 405 nm resins; initial test prints are advised to fine-tune layer time and support settings for your specific machine and geometry. After printing, clean parts in isopropyl alcohol or another suitable solvent to remove uncured resin, then perform a final post-curing step under a 405 nm light source or UV chamber to achieve final mechanical properties and dimensional stability.
Usage recommendations
Handle resin with nitrile gloves and work in a well-ventilated area. Store the unopened container in a cool, dark place away from direct sunlight and heat sources. For best results, perform small calibration prints to determine optimal exposure times and support placement for complex geometries, and follow standard safety procedures for resin handling and waste disposal.
