Takoto HE20

All metal (tested to >320°C) 400c validation in progress Dual vertical heater cartridges (standard Ø6.0 x 20mm, any wattage that your machine can support), clamped in for good thermal transfer Standard Ø3.0 x 15mm temp-sensor (thermistor or PT100/1000) clamped between the heaters & the nozzle for accurate sensing Standard E3D Volcano nozzle, which are readily available in various materials & work well Very rigid structure via 3 titanium hollow pillar mounts, because crashes happen and threaded heat-breaks can bend, tear out, or break The heat is retained to the melt zone by the titanium feed tube & copper heat sink, significantly limiting heat-soak to the filament in the feed mechanism Very well cooled via modular fan options Protected with a high-temperature silicon sock to minimize heat loss (increase efficiency) & for safety Please note that derfault is a "bare" Hotend - it does not include an extruder, heater cartridges, temp sensor, or fan.     More information can be found on the Takoto website.
