Custom high temperature heat sink upgrade for Ultimaker 2/2+/Go/Ext

This heat sink enables 3d printing polycarbonates, nylons, Ultem™ (PEI), PEEK and most other high temperature thermoplastics, and yet still prints more conventional plastics such as PLA, PETG, and ABS, with ease. This system was tested up to 400˚C extrusion temperatures and 85˚C ambient temperatures.This listing is for heat sink only. Hot end heater block, heat break, heater, sensor, and nozzle are extra. Uses the 25mm heat sink fan already found on the Ultimaker 2 series machines.  A firmware upgrade is needed to enable high temperature use. This system uses E3D Kraken / Chimera style heat breaks, E3D style or compatible heat blocks and E3D style or compatible nozzles. Made in the USA by DM-Accessories. See Also: A custom aluminum heater block uses the Ultimaker's heater and sensor cartridges. This system does not affect the machine's usable build area or build height and it reuses existing parts whenever possible. Compatible machines: Ultimaker 2 Ultimaker 2+ Ultimaker 2 Extended Ul
