Comparison for Three Different Extruders

PLA Extruder

Enhanced Cooling.

Best for low temperature filaments, e. g. PLA.

ABS Extruder

General Extruder with Fan Duct Switch.

Capable of printing high temperature filaments, e. g. ABS

TPU Extruder

Better Feeding Less Jamming.

Best to work with flexible materials, e. g. TPU

Size of Fan Block

A bigger fan block provides extra air circulation flowing in higher speed, and easily takes away more hot air.

Regular Fan Block provides enough cooling for air circulation.

Feeding Mechanism

Same as previous version yet better.

Same as previous version yet better.

New feeding mechanism created specifically for printing with flex material, with 0.5mm nozzle.

PTFE Tube inside the Heating Block

Purpose: To help the filament fed into the nozzle properly, and avoid it being heated too much and cause blockage.

Yes, it has a PTFE tube inserted in the extruder throat.

PLA filament has high tendency of heat deformation.

The inside wall of the PTFE tube is slippery with less friction. It prevents the filament deformation under high temperature.

No, it does not have a PTFE tube inserted in the extruder throat.

The ABS filament has high level heat tolerance rate and less deformation under high temperature.

Yes, it has a PTFE tube inserted in the extruder throat.

The inside wall of the PTFE tube is slippery with less friction. It guides the filament like TPU which tends to deform in high temperature .

Fan Duct Switch

Purpose: Control the air flow.
Open the switch: allow the air blow straight to the model, and let it cool down fast which could prevent dripping and model’s tip from burned.
Close the switch: block the air blowing to the model to cause the warping.

No, it does not have a switch.

Yes, it has the switch.

We recommend you to utilize the switch in the following ways.
Close: when printing the raft to prevent warping.
Open: when printing the model body for better cooling effect.

Yes, it has the switch, which should be always open.

Fan Duct

Because it has no switch, more cold air flow through.

The air flow can be controlled by the switch on/off/semi-open according to the needs.

The air flow can be controlled by the switch on/off/semi-open according to the needs.

Features

Hold the Button while having difficulty to withdraw the filament.

Nozzle Compatibility

0.2mm, 0.4mm, and 0.6mm

0.2mm, 0.4mm, and 0.6mm

Have to larger than 0.5mm
