As the FFF/FDM 3D fabrication process becomes more accepted and popular in industry, the demand for products with higher anti-abrasion capability, higher durability as well as the ability to withstand higher temperature is growing fast. The materials for this type of product are known as "super engineering plastic" and materials such as PEEK and TPI are the examples.<br/> Due to the high temperature requirements, the existing hotends which are made for lower temperature materials like PLA and ABS are not capable to handle the material. A revolutionary new concept hotend for high-temperature usage in the range of 300 °C to 500 °C has been developed specifically designed for the super engineering plastic materials.<br/> The new hotend is compact in size and the thermal capacity is small accordingly compared with the conventional units, but it can follow the precise temperature requirements and fine adjustments as needed. Unlike the others, this hotend does not need a large cooling system (either forced air or liquid coolant) to prevent the heat creep on the cool end of the extruder. It is more energy efficient and eco-friendly as it heats when it is needed. Also, thanks to the size and weight, multi-nozzle device will be feasible in the near future.<br/> With the new design improvement and ability to monitorcontrol the hotend temperature more accurately, it is much more clogging-resistant of filament material than existing or even our own previous year's hotend.
