<p>Is it possible to construct a Production Possibility Frontier (PPF)  for 3 goods? Would this require a 3D graph and a part of a sphere, in one quadrant (as opposed to the usual 2D plot, with a part of a circle in one quadrant).</p>

It is possible. In fact you can construct PPF for arbitrary number of goods.

When it comes to plotting it for a case of 3 goods it is easy to make 2D projection of the 3D space. You can see the image below for an example.
