ESUN Flex Resin Is The Most Ductile eSUN Resin

eSUN Flex Resin has the properties you need for a 3D printed object that needs to bend or twist to perform at its peak. Anywhere you might traditionally have used TPU, whether 3D printed or otherwise, eSUN Flex Resin can bend, twist, and stretch more than any other resin printed part can before breaking.

Here are the key features of eSUN Flex Resin: 

  • Use in place of TPU 3D printed parts

  • Extremely flexible finished 3D prints

  • Resists tearing even along small sections

Replace your TPU parts with eSUN Flex Resin parts

TPU 3D printed parts can be challenging to print effectively, with difficult overhangs and relatively low detail that can be achieved. eSUN Flex Resin retains the properties you would come to expect from 3D printing resins like high resolution finished parts and capable of printed unsupported over extreme overhangs and boosts these qualities with incredible flexibility.

  • Usable as little as 0.025mm or as large as 0.05mm layer heights
  • 85-90A Shore Hardness
Vibrant Colors

Resin Parts

Incredibly Elastic for Tougher Handling

Some 3D prints spend their life mounted to machinery or left on a shelf and others face intense conditions where they are dropped, fumbled, and ran over. 3D printed parts made from eSUN Flex Resin don't snap or shatter like other 3D printing resins, so you can use your 3D prints worry free that a careless moment means the end of your print.

  • Tensile strength: 6 - 8 MPa
  • Bends before breaking
  • Perfect for small, highly detailed models with intricate cross-sections

Resists Tearing When Under Stress

This 3D printing resin creates parts and prototypes that are tougher than most, resisting tears and stretching far beyond others' capabilities. 

  • Test pieces stretched 2 to 4 times as long as printed before breaking
  • Tear strength of 390 - 420 KN/m

  • Slice Setting Tip:
    • Use denser supports to avoid support separation
    • Higher lifting distance (>6mm)
    • Slower lifting speed (<60mm/min)
    • Longer light off delay (>6s)
  • Post-Processing Tips:
    • The more UV exposure, the harder/less flexible the finished 3D print
    • Consider only soaking in isopropyl alcohol and cleaning without a post-cure to retain flexibility
  • 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.
