Well if you wanted to enlarge something in some proportionality to your original object you'd need to create some amount of mass from pure energy E=mc^2. You have to find out how to do this first.

If you can get the mass elsewhere then you might as well simply conventionally build the desired object?

As for shrinking something macroscopic... kaboom! I can't see it working on a macroscopic level.

So to answer your question as for enlarging/shrinking macroscopic objects by some sort of 'diabolical ray beam device' it would be the energy costs/massive explosions.

[tex]l = l' \sqrt{1 - \frac{u^2}{c^2} [/tex]

[tex] u = [/tex] velocity

[tex]c = [/tex]speed of light

[tex]l' = [/tex]length in inertial frame

[tex]l = [/tex]length in reference frame

thus an object moving at all will "contract" by an amount, according to relativity:

[tex]\sqrt{1 - \frac{u^2}{c^2} [/tex]

But perhaps I've misunderstood the question?

Interesting discussion of the square/cube law here

The obvious upper limit is melting the object before it gets big enough!
