Why is PP difficult to extrude ?

PP is a difficult material to extrude because it tends to shrink ovally.

Why is HDPE difficult to extrude ?

HDPE is a difficult material to extrude because it tends to shrink ovally.

Material selection – Choosing the right polymer

Properties and processability should both be taken into account when selecting your 3d printing material.

DIY build your own fumehood

Additives enhance certain properties of the polymers. Only basic understanding of extrusion is required to process these composite filaments.

Mixing inert additives homogeneously

Additives enhance certain properties of the polymers. Only basic understanding of extrusion is required to process these composite filaments.

Additives & Composites (Vol. 1)

Additives and composites bring even more diversity on a market already full of polymers. Yet these remain simple concepts accessible to anyone. Read the first part of this really interested topic and see for yourself!

Additives & Composites (Vol. 2)

Additives enhance certain properties of the polymers. Only basic understanding of extrusion is required to process these composite filaments.

Intro – What is Extrusion (Vol.1 Polymers)

In these series of articles we will get the fundamental knowledge about extrusion starting from an introduction to Polymers.

Intro – What is Extrusion (Vol.2 Extrusion)

In the second part of Introduction articles about extrusion, we try to explain with simple words, what exactly is extrusion, what happens to the materials when we extrude them, amd how an extruder machine works!

Technical Datasheet Walkthrough (1/3)

In the series of "Technical Datasheet" articles, we will try to focus on a rather simple but also important topic, that of the technical specifications that comes with any polymer out there.
