Large Manual 3d Printer

Build: Make an x y table with v slot. Use a long piece for the x dimension. Put a tracer on the left end and a 3d pen on the right end. Put a lab jack where you want to create your art. Make it about 10 inches below the surface of the x y table. Put a flat substrate on the lab jack and crank it as high as you want to start. Adjust it to be the same level as the x y table. Draw away!

This is the largest printer I have found. It is also the cheapest. The reason is that it is run by hand, without computer or motors or electronics. Put an object on one side and move the 3d pen while tracing the object. Move the z dimension by turning the crank on the lab jack to move the printed copy down a notch. Be creative!

Here are some other options with photos of wood builds found on the net.
