Direct Granules Extruder V3 is a prototype you can build from cheap, commonly available materials with low tech tools. It is not for beginners in 3D printing, but advanced tinkerers should be able to make a copy. Since not being intended for beginners, I don't provide a step by step build instruction. Instead you get drawings and pictures in the "files" section that should enable you to create your own extruder.

Another issue is, that this design is based on other physical principles than existing extruders. It is essential to get a deeper understanding of those principles that I have described in the logs of this projects that also include videos.

Leave a comment if you still have questions about the build process of the direct extruder.
