Continuing along the theme of supporting one of the best 3D Printer manufacturers on the market, we present Flex3Drive for the awesome Ultimaker 2 range of printers, making them even better. The UM2 machines represent yet another leap beyond what they did with the Ultimaker Original design. Flex3Drive for UM2/UM2+/UM2e can extend the performance of your machine to produce even the most complex retract-intensive prints, and print at layer heights lower than you have done before.

Supplied with a precompiled updated firmware, an improved Teflon coupler that withstands higher temps (270c), and firmware code available on the Ultimaker Github repository along with our own updated version (see link below). Installation is straight forward and fully reversible to maintain your warranty. This design was produced alongside the engineering department at Ultimaker, making it yet another approved upgrade for their machines. Furthermore the Flex3Drive is fully compatible with the Olsson block upgrade.

Compatible with all printers in the Ultimaker 2 range including UM2 UM2+ UM2e and UM2go
