Flex3Drive Original – 3rd Generation

This is our rock solid baseline version of the Flex3Drive from which other variants are developed. This is the result of a design process that has gone through countless iterations and not hundred but literally thousands of hours of printing, and not over weeks or months, but quite literally years of testing and development. This is a mature, refined product!

From the numerous innovations we have pioneered, this extruder includes our Two-Bar rigid tensioner system with a quick release lever and optional screw based arm, and includes integrated hotend and carriage mounting features. We are really proud of the journey and the result it produced. We hope you like it too.
