BUILD 3D industrial large format printer (1200mm X 1000mm X 600mm) — 2

I need you to help me to design and BUILD industrial large format 3D printer (1200mm X 1000mm X 600mm).
I need to print filaments with carbon fiber like NYLON with carbon or polycarbonate… High temperature.
I was thinking to use VORON kit and modify it with your help, but I am open to any new designs. Size and precision is most important for me.
Please only contact me in case you already build something similar before.
