Tiertime UP Box+/UP300 3D Printer PLA Filament Extruder - High Precision Printing for DIY Projects, Prototyping & Home Use

Product Name: PLA extruder Compatibility: UP BOX+/ UP 300 Internal Structure Comparision: PLA extruder V.S. ABS extruder Size of Fan Block: PLA extruder comes with bigger fan block provides extra air circulation flowing in higher speed, and easily takes away more hot air. While regular Fan Block in ABS extruder provides enough cooling for air circulation. .PTFE Tube inside the Heating Block: a PTFE tube inserted in the PLA 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. While ABS extruder does not have a PTFE tube. .Fan Duct: PLA extruder do not have switch, more cold air flow through, which blocks the air blowing to the model to cause the warping. While the air flow can be controlled by the switch on/off/semi-open in ABS extruder according to the needs.
