ESUN Tough Resin Mimics Industry Standard Polymers

eSUN Tough Resin was formulated as a rigid and impact resistant, mechanically-ready option suitable for final-use applications. Other 3D printing resins are best suited for decorative or prototypical examples, but eSUN Tough Resin is strong enough to be drilled and resist shock without shattering.

Here are the key features of eSUN Tough Resin: 

  • High strength mechanical properties

  • High precision 3D print resolution

  • Formulated for monochrome LCDs

Unparalleled Mechanical Performance with eSUN Tough Resin

Whether it's a prototype that needs to survive rough handling or a fixture that may face repetitive impacts, eSUN Tough Resin is well suited for the job; strike at a finished 3D print using eSUN Tough Resin with a hammer or drill right through the part without disturbing its structural integrity.

  • High impact resistance
  • High strength
  • High hardness
  • High toughness

Low Viscosity for High Precision

When you're 3D printing with resin, you're often trying to achieve the highest resolution possible. The low viscosity of eSUN Tough Resin makes it well suited to flow and recede as the 3D print job progresses, allowing uncured resin to drip off the finished sections and reflow into the space below the 3D print to begin the next layer.

  • 200-00 mPA-s
  • Easily reflows as 3D print lifts from vat
  • Drains from 3D print to prevent blown-out features

Monochrome LCD 3D Printer Ready

Nowadays most resin-based 3D printers use monochromatic LCD screens to mask each layer, a dramatic improvement for longevity and performance over older RGB LCD screens. eSUN Tough Resin has been reformulated to perform exceptional well with monochrome LCD 3D printers for ultra-fast 3D printing.

  • Extensively tested with profiles for the most popular resin 3D printers

  • eSUN Recommended Post-Processing Steps:
    • Remove the printed model from the build plate
    • Submerge the model in isopropyl alcohol, preferably in an container within an ultrasonic cleaner
    • Submerge the model completely in distilled water and expose to UV lamp or sunlight
    • Place the model in an oven, set the temperature to 50°C (122°F) for 20 minutes, turn off oven, and let cool until oven reaches room temperature
    • Normal prost processing (support removal, polishing, etc.)
  • Wear protective gear such as nitrile gloves, safety goggles, etc. before handling resin.
  • Shake the container of resin well before using it.
  • Avoid leaving the resin in a vat unused for more than one day.
  • Do not store used resin in the same container as unused resin. Pour used resin from vat into a separate light-proof container.
  • Handle resin in a well-ventilated room over protective surfaces like a silicone mat, aluminum trays, plastic sheets, etc. when possible.
  • Cure resin under UV light before disposing with regular trash. NEVER dump wet, liquid resin in the trash unless it's being properly disposed of with hazardous waste. Contact your local hazardous waste facility for further appropriate steps.
