If you took that printing setup that had the brick like consistency and took a steel string. That could articulate across the face of the port then out along the bottom a few centimeters and vibrate. Then you could use it as a gluing and cutting line. Then with a internal rutter inside the nozzle you could do turns. Then just use smaller lines for wetter materials. As for anything chunky that is a nightmare. You are always better off mixing in the end of the nozzle than ever trying to transport it. If you have to print with it then it is better to print a cheap forum that can be easily removed then separate nozzle for fill. I guess you could print with it... it would just some well placed turbulators.

very informative thank you sir

Hello.Thank you very much for such a informative presentation. I would like to know what software did you use for the simulation of flow?
