Introduction

The extrusion machine has quite a specific output, a line. This is well suited to make new granulate and 3D printer filament. However use your creativity and you will find other applications for it as well. Change the nozzle for different shapes and sizes, turn it around a mold to make lamps or a handle for a knife.

The extrusion machine consists in 6 different elements: the hopper, the barrel, the nozzle, the barrel holder, the framework and the electronics.

Step 1 - Hopper: cutting metal plates

Get the metal sheet plates. Take measurements following the blue prints and cut the sheets with a grinding machine and sand metal edges.

Step 2 - Hopper: drilling metal plates

Prick the plate with a hammer and drill the metal plates on the milling machine


Step 3 - Hopper: welding metal plates

Make a pyramid with the plates and weld them together

Step 37 - Improvements and learn

Suggestion: Currently, the nose decided the amount of plastic that comes out.

However, a better way to do this is by adding a controllable engine. There are different ways to control the speed of an engine by using different controllers or regulators.
