ETEC E-ToughFlex

ETEC HARD PLASTICS
E-ToughFlex
3D print strong parts with a beautiful surface finish
With E-ToughFlex resin, you can produce extremely strong parts, with nearly four times the impact resistance as most engineering plastics. Compatible 3D printing systems for this material are those based on continuous digital light processing technology (cDLM) such as Envision One cDLM Mechanical or Envision One cDLM HT.
Long-lasting and flexible parts 3D printed with water-fearing resin
E-ToughFlex™ has a very high flexural modulus and strength and it is hydrophobic (water repellence). Parts 3D printed with E-ToughFlex are strong, yet flexible and have a beautiful surface finish similar to ceramic while having a great abrasion resistance.
