We tested some more, with another material, and even without a proper extruder it is going pretty well.
The newly designed pressure chamber, responsible for adding the concrete is working brilliantly, as you can tell from the small test movie.
After some serious thinking and engineering, Kees Koese came up with the idea for this extruder. In green, but hey….
Four layers in one go. Not exactly precise but very proud with the result so far. We are going to use a much smaller nozzle in a week
So now, when the pressure sensors are in, everything is mounted together, we can finally start with some serious completely digitally managed printing. Can’t wait….
