Making filament, the industrial way

Please watch the video below! A medium sized company will explain the efforts and machines needed to make commercial filament. From what we see, the machine may cost around 20 000 Euro upwards and requires a quite a long time to tune in all parameters. There are also machines for 8000 Euro with all incl. but to make profit from this activity you need at least 40 of them ..

Ready to use machines

In even larger environments, there are machines called the ‘filament miles’, exceeding easily 5 meters. Such machine can cost around 35000 Euro. Here some thoughts building one from scratch.
