Who does fabrication?
Is it easy to fabricate yourself?

For a moment I thought you meant Encapsulated PostScript. Which would've been odd.
FWIW, my experience is that for one-offs, it's easy to buy a large chunk (or reuse a handy bit lying around) of expanded polystyrene, and simply cut bits out of it to suit. You can use a sharp knife or a hot wire. The wire is smelly and probably bad for you.
You can also buy expanding foam filler in a can (polyurethane, I think, not polystyrene), which might do the job depending on the project. You squirt it in, it expands, dries, hardens. Then you can trim to suit with a knife, and even sand/fill/paint or whatever. My experience is that it is worth following the instructions - they mean it about not getting it on anything you don't want it on, and it keeps expanding for quite some time after you stop squirting, which can be Bad if you weren't expecting it.

Well, I had an idea for a microindustry (selling mainly over ebay), so hand-built-at-home isn't really what I want. Be OK for prototyping tho, obv.
I might look at pourable resins (with filler) too.
I filled a large gap in a wall where some shower pipes used to be with the canned stuff. Waited at least a week before painting, iirc, and the paint's cracked a bit where it was /still/ expanding
