Filament extruder screw and barrel
Suitable for pellet 3d printers?
Filament extruder screw
Barrel and nozzle
Screw size 8mm, 12mm, or 20mm
Why do you need Filament for 3D Printing?
Fused Filament Fabrication (FFF) or Fused Deposition Modeling (FDM), is an additive manufacturing process that belongs to the material extrusion family. In FDM, an object is built by selectively depositing melted material in a predetermined path layer-by-layer. The materials used are thermoplastic polymers and come in filament form.
FDM is the most widely used 3D Printing technology: it represents the largest installed base of 3D printers globally and is often the first technology people are exposed to.
Why Not a pellet extruder for 3D Printing?
When a habit comes to be a tradition, it seems we lack thoughts of change or challenge on it. What can we benefit from pellets other than filament?
a. Saving on cost, energy, and time. If we use 3D Printing Filament as a tradition, we have to produce the filament in advance, which is time and energy cost. If we can print from the pellet, we do not have to re-meld the pellet.
b. Recycle precious plastics from to be waste or pollution. PET bottles, and plastic waste seems everywhere in our daily life, if we can find a way to reuse them, it's precious to the earth and our coming generations.
We are going to upgrade the 12mm screw barrel with a square flange
We are going to release a new 8mm single screw and barrel 25mm diameter which is suitable to work with the NEMA17 stepper motor and the 25mm mica band heater.
A new design of an 8mm single screw and barrel will be available in Aug. 2019
Compression Ratios: 8mm No compression, 12mm compression ratio is 2.2
Planetary geared stepper motors are recommended for pellet extruders.
