Now I'm sure this is just like any 'as seen on TV' product and it doesn't work nearly as good as advertised or initially assume (they things NEVER ARE!!) but either way this would be a good learning experience.
Well Provided You could actually afford to buy, rent, or use a 3d printer this would be something awesome to test out. Me personally, I think I'd start with the 3d printed guns then move onto 3d printed organs....you know the interesting (albeit EXTREMELY CONTROVERSIAL) subjects.

Instructions
1. Find a 3-D printer, preferably one that builds objects in thin layers of plastic (a process called fused deposition modeling). If you don’t own a 3-D printer, can’t borrow one, or lack the funds to buy one—typically $500 or more—you can pay an online company (such as Shapeways or RedEye on Demand) to print a design for you.
2. Download Urzhumov’s design file at here and print it out. (The default thickness is 1 centimeter, but it can expand as tall as a 3-D printer allows.)
3. To use the invisibility cloak, line the disk’s inner ring with aluminum foil, lay it on a flat surface, and put an object 5.4 inches long or less inside. Any microwaves shining on the disk’s outer edge won’t reveal your precious property.

Good luck getting that file. Also, in order to create cloaks in other wavelengths, visible light for instance, you need to be able to create holes that are as small as the wavelength of light that you are trying to reflect. The loophole in the law of optics is simple : You can bend light back on itself, in the same wavelength. This means that you can catch the wavelength and then loop it back in the same direction it came or, any direction for that matter. To do this in smaller wavelengths you need some complex erosion techniques that wouldnt be able to be done by an average DYI'er.
If you could however, doing this in thin transparent layers (perhaps holograms) would allow you to stack layers of holes for different wavelengths of light. This compounding effect might allow for the ability to combine layers for a multi-spectrum cloak. This would be a technology that no one would want you to have. Creating a full spectrum cloak would make even nuclear warheads invisible. I imagine this will be a closely guarded secret if it is done successfully.
However, thanks to Moore's law, and the need to stop bleeding of electric currents through microprocessor channels, the ability to create small nano-scale holes will become more prevalent. Thus the chance of creating materials that could do the job.
