Filament for the printer is created on our own modified Lyman / Mulier version 5 Filament Extruder:

This printer was designed to print very large scale using recycled ABS plastic (we also recycle, shred and produce recycled ABS filament).
Most of the other very large scale printers out there tend to print in PLA which is a lot less problematic at large scale.
Main features:
If anyone is thinking to build something like this I would recommend using a 12mm heat-bed plate (rather than 6mm) as the aluminium plate deforms up to 5mm when heated to 90 deg C, I am using 9 x 9 point auto-bed leveling to pick up the deformation shape).
Also the 400mm x 400m 600W silicone heaters are a little small as the distance between them causes around a 10 deg C difference on the heat-bed surface between the heaters and above them).
I'm Currently building a new dual 100mm stack extruder with 8 x 40W heater cartridges to allow for a 4 x increase in flow rate over the current design, as the printing speed at this volume is way to slow, once this is done I will share some more of the design details.
There is an image of the wiring (Sub33d_v3.07_stepper_and_heatbed_wiring_diagram_v1.00.zip), which can be used to connect many different 3D printer boards to external CNC type drivers, I used the RAMPS 1.4 in the wiring diagram as this seems to be one of the most common boards.
An old server ATX power supply was used which was around 1000W, although a 500W supply would have been fine.
Only the 12V output was used.
The max current draw is the sum of the following:
Which comes to around 19.5A peak at 12V, (please note this does not include the heatbed, which runs off 230V AC mains power at 2400W)
Special thanks to Substation33 for all the support and recycled materials.
