SKU CH-WETN-1HDPH

Direct-drive extruder kit with all-metal hotend reaches 300 °C, delivers 80 N force via 3.5:1 dual gears, and weighs 288 g in a 54 × 50 × 64.3 mm package

  • TypeOther
  • Direct drive extruder prints flexible filaments like TPU and PETG reliably
  • Dual-gear 3.5:1 gearing delivers up to 80 N extrusion force for stable feeding
  • All-metal hotend reaches 300 °C for high-temperature materials such as ABS

  • Dual-fan cooling ensures efficient heat dissipation and steady print quality

Direct Drive Extruder Kit for Ender 3 Series

The Sprite Extruder Pro Kit upgrades Creality Ender-3 series printers with an all-metal direct drive extruder and hotend. It includes a short cable for BL Touch or CR Touch connection and enables printing of flexible filaments such as TPU, PLA and PETG. Firmware for the upgrade is available from the manufacturer's website.

3.5:1 Gear Ratio and 80 N Extrusion Force

Dual toothed gears with a 3.5:1 ratio deliver up to 80 N of pushing force for stable, precise filament feeding without damaging the material. The compact assembly measures 54 by 50 by 64.3 mm and weighs 288 g, supporting both direct and Bowden configurations. It handles PLA, PETG, ABS, TPU and other flexible filaments at temperatures up to 300 °C.

300 °C All-Metal Hotend Limit

The all-metal hotend reaches 300 °C, which is the practical ceiling for standard thermistor-based temperature control and PTFE-free heat breaks. Beyond this point thermal creep and sensor accuracy typically degrade, requiring specialised high-temperature components not included in this kit. Dual fans with metal covers provide active cooling to maintain stable extrusion at the upper end of this range.

Questions about this item

Will the Sprite Extruder Pro Kit fit my Ender 3 V2 without changing the existing hotend mount?

The kit combines the extruder and all-metal hotend in a single 54x50x64.3 mm unit weighing 288 g, designed as a direct replacement for the stock assembly on Ender 3 series printers.

How can I confirm the 3.5:1 dual-gear drive is feeding correctly after installation?

Load filament and watch the drive gears; the double-toothed structure should grip without shredding, and the 80 N extrusion force delivers steady, skip-free flow during a test print.

Does the box include the BL Touch cable and firmware, or must I download them separately?

A short cable for connecting BL Touch or CR Touch is included; the required firmware has been released on the manufacturer's official website for download.
