QIDI Polar Cooler

The QIDI Polar Cooler is an advanced external cooling solution for FDM 3D printers designed to actively cool the extruder’s cold side and filament feed path. It prevents heat creep-related issues and improves reliability when printing with temperature-sensitive and engineering materials.

Prevents heat creep and clogs

Efficiency air-cooled direct-blow extruders and filament，reduce the Clogging Situation by 90%.

Optimizes extrusion temperatures

Active cooling air control system,optimizes extrusion temperatures.

Improves overall print consistency

Chamber heating and polar cooler on，ensure that large-sized PLA does not warp at the edges.
