Volvo 3D-printer Truck

This is my idea for a futuristic construction machine. In the world of the future, technology has made life fastrer. There's no longer time for traditional construction, instead materials are created on site using the Volvo 3D-Printer Truck. This machine consists of an industrial-scale 3D-printer conected to a cockpit and 4 giant All-Terrian wheels.

I tried to design the model in the traditional Volvo colour scheme but the frames I needed only come in grey and some other parts only come in certain colours. This model features rotating wheels, an adjustable printing arm in the 3D-printer (hand-operated from the top), and an opening hatch on the bottom of the 3D-printer so it can print directly onto the ground
