This “extra length” improves output consistency, keeping your filament extrusion to the appropriate range. Use the Filabot Melt Filter Nozzle to help decontaminate your recycled materials for a clean, consistent filament. The stock nozzle is good for lower output applications where the voltage is under 25 volts. If using on higher voltage it will result in die drool. The 2x nozzle is better because it provides more laminar flow (less die stress at exit) and allows the filament to cool slightly during exit compared to stock. The 2x nozzle works up to 50 volts. The 3x nozzle is used for very high index plastics like PET. It aids in the pull down on exit and allows the filament to cool even more than the 2x.
We recommend using a filter with a mesh opening size 75% or less of the 3D printer nozzle size
Screen 1/2" (13mm) Dia 20 Mesh Support Screen (0.381mm Opening Size)
Screen 1/2" (13mm) Dia 60 Mesh Coarse Filter Screen (0.229mm Opening Size)
Screen 1/2" (13mm) Dia 80 Mesh Fine Filter Screen (0.178mm Opening Size)
These nozzles are to make 1.75mm or 3mm, ABS, PLA or other types of filament. We also offer a pre-drilled nozzle for users who are looking to make custom size extruder nozzles. Pre-drilled nozzles have a 1mm hole. Please note that the nozzle size will be a different size than the filament that is being made. It is best to pull down the filament to the correct size.
PLEASE NOTE: This accessory is NOT for filtering highly contaminated plastic. This is to help filter small particles that were missed in the decontamination process. Anything added to the hopper MUST be clean of dust, dirt, paint, coatings, and tape, etc.
