I wanted to show off something we are currently doing at work (a research institute). We have put a screw extruder on an industrial robot from ABB which will allow us to print up to 6x2x2 m. Using tool changers we will also be able to change the extruder to a machining tool to get nice surface finish.
I hope you will find this short teaser video interesting. If so, I can come back and share some of the prints we will do in the coming weeks.
