Definitely possible Oddjob. The side panel badges would be a great start, sketch out what you want it to look like on a piece of paper, and then make a JPEG of it with your phone and import it into a program like Adobe photoshop, it can then be straightened and rounded off in any way you want, but I'm not the person to tell you how to do that, you'll need a "Yoof" to show you how, I'm old school when it comes to drawing! As far as materials go, you can stereo lithograph in metals, like bronze, but it uses a laser to fuse bronze powder, and very intricate patterns can be made, rather than a printer that deposits a plastic dot just like your home printer does, layer by layer.. Don't try lazering aluminium or magnesium powders though, they will burn like thermite! You would make a pattern to the shape and size you want with the filler material, and then make a mold depending on what material you want to cast, rubber, plastic or metal.Very small tolerances can be printed, down to microns in some instances. Here's a video what can be achieved.:http://youtu.be/DAQm5P5p4zwThere are limits to the size you can print, big printers are more expensive than the small ones.Yes if you have inlays just print the separate parts and cast the different colours, then join them later.
