Filament Quality Guide

Find all your filament issues here, learn why they are happening, and of course how to fix them! This way you will hopefully figure out the optimal way to process your material into proper quality filament.

Nozzle build-up

In this article is described what nozzle build-up is and how it can be prevented.

Bumps or particles in filament

bumps or small particles are sometimes visible on the produced filament. In this article is described what could cause this bumps and how you can fix it.

Output too low or thin

In this article is described what to do when the output of material is too low.

Waving/Curling filament

In this article is described what could cause a polymer to start waving between the nozzle and the IR sensor. This article will also cover the possible solutions.

Polymer degradation

In this article is described what could cause a polymer to degrade while being processed on the Filament Maker.

Abnormal smoke production

In this article is described what could cause abnormal smoke production and how you can solve this issue.

Output is too liquid

In this article is described what could cause the output of material to be too liquid and how to solve this.

Filament thickness deviation (inconsistent diameter)

This document teaches about all the possible known causes for filament thickness deviation. Please note that there are so many variables related to this problem, that a 100% fix is of course unrealistic. But by reading this document you will at least learn what these variables are, which is the first step in fixing the issue.

Oval or flat filament

A very common problem during filament extrusion is that the filament produced with your filament maker is oval or flat shaped. Filament ovalness (or flatness) can cause 3D-printing problems. This deformation of the filament can have two different causes, which will both be discussed here, as well as potential fixes.

Air bubbles or holes in filament

In this article you will learn all the possible causes for why there are bubbles in your extruder filament, and how to be able to fix this.

Rough filament surface

Streaks can appear on the surface of the extrudate that exits the nozzle of the extruder. This phenomenon makes the surface rough and can worsen over time, unless the problem is fixed.

There are not available articles for this topic just yet! Don’t worry though, we are working on that! New articles and videos are added to the platform almost every week! In the meantime if you have any questions let’s discuss them on our forums.
