Guide: extruding the most common polymers with Felfil System

Felfil System has some settings that require a little bit of tuning to get a perfect extrusion. They are different for each material: download our guide at the bottom of the article!


One of the most important features of a filament extruder is compatibility with a wide range of materials. When we created Felfil System, this was one of our main goals: and we are proud to say that our System can produce 3D printing filament spools starting from various polymers.

There are two main ways to use Felfil System for the extrusion: you can start from a common polymer, such as PLA or PETG (in the form of pellets or plastic wastes), or choose to create an experimental filament, testing innovative materials or combining new and different substances (for instance, we enjoyed extruding filament with coffee, or with a percentage of orange peel – in the latter case for research purposes).

As it is easy to imagine, in the latter case the extrusion parameters must be set from time to time according to the polymer being tested, and they have to be evaluated according to the specific circumstances.

When the extrusion starts from the most common materials, however, there are settings that guarantee the best performance. You just need to identify the best combination of settings such as temperature, motor extrusion screw speed. It is usually possible to determine them after a few attempts, but for ease we have collected the best setup in a short guide that can be downloaded for free at the bottom of the page.

What is in the guide?

The guide includes a brief introduction to Felfil System and best practices, and an overview of the main materials that can be extruded into 3D printing filament. In particular:

  • ABS
  • PLA
  • PETG
  • HDPE
  • HIPS


And in the last page you will find a section with some ideas for experimenting wih alternative and colored filaments. Download the guide below!
