Double gear feeding makes printing more stable High hardness and wear- double gear feeding, effectively resisting repeated feeding and retreating of materials And the wear caused by fiber consumables, extending the service life. Large extrusion force up to 80N The gear transmission adopts a 6.25:1 reduction ratio, which is perfectly matched with the motor. The extrusion force is up to 80N (depending on the consumables), and the feeding and retraction volume control is more precise. Compact and 6.25:1 reduction ratio. Drive: Dual gear drive Maximum force: 80N (depending onconsumables) Measuring ratio: 6.25:1 Supported consumablediameter: 1.75+0.05mm Vehicle accessories: for -5 Max (The product printed words depending on the batch, but this does not affect use) Color: As Shown Material: ABS Package Contents: 1 x Extruder Kit Only the above package content, other products are not included.
