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 a 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 pellet extruder for 3D Printing?

When a habit comes to be a tradition, it seems we are lack of thoughts of change or challenge on it. What can we benefit from pellet other than filament?
a. Saving on cost, energy and time. If we use 3D Printing Filament as tradition, we have to produce the filament in advance, time and energy cost. If we can print from pellet, we do Not have to re-meld the pellet.
b. Recycle precious plastics from to be waste or pollution. PET bottles, plastic waste seems everywhere in our daily life, if we can find a way to reuse of them, it's precious to the earth and our coming generations.
