Both programs are capable of 3D printing. We have a 3D printer at school and we send an AutoCaD 3D model to print. It takes about a day for them to print, as they usually do about 6 models at once and it takes a while to build up all of the levels..
I have some pictures of some of the 3D printed parts, but I have to reformat them for posting. I can do that and put them up later.... There are some real cool ones....
