I posted the link mostly to give you an idea of what pieces of machinery besides the extruder itself make a monofilament production system, not to suggest that you buy that one (it isn't new, btw)
Sorry, I should have said a bit more when I posted earlier.

It would be really good news if we had a good supply of plastics. Getting other, more rare, plastics into 3mm fillament might be even more valuable.

Well I have also found:-
[www.tempatron.co.uk]
They don't list ABS as a format that they sell, but they do talk about it. They do larger reels, but not in 3mm. I have sent them an email to find out whether they can do ABS as well. And we can get it in multiple colours.

Reading your link it sure looks like they offer 3 mm ABS. 3 mm is a very common size for plastic welding rod.

I can edit the wiki but perhaps we should try them out first before recommending to everyone.

is it?
one pound sterling is about two dollars,
so 1kg ABS is about 28 US$
that's 12.70 $/lb
for 5lb that's 63,50 $ compared to 45$ at the rrrf store.
1kg HDPE is about 15.28 US$
that's 6.93 $/lb
for 5lb that's 34.65 $ compared to 25$ at the rrf store

These are the guys I use. They ship overseas, though mostly to South America. Jim Waring and Donna are good folks.
[www.newimageplastic.com]
Their prices for ABS are a bit higher than Village and their lead times for small specialty orders can be a bit long in that they don't keep much stock. Their quality is good, however.

... this lets me remember an old thread about fabbing objects out of uniform shapes - as lego does from bricks, here stacking small uniform spheres to a bigger object.
So you haven't to remelt the balls, but simply heat a small zone on the base and pick-n-place the balls into the molten area.
With smaller spheres (e.g. 1mm diameter or even smaller) you should have a finer granulity and with short over-heating the actual fabbed surface you can weld the spheres together and apply a smooth surface-finish ...

My Dad & i were discussing ways to reduce FFF warping. he came up with the idea of welding lots of little spheres together by surface melt, not total melt. This means the thermal expansion is limited to the skin, not the volume.
We couldnt think of a good way to heat just the skins though, especially in 0.2mm size grains.
Microwaves?

This sounds similar to sintering, but certainly not the same process. Borrowing from that idea though, I suppose you could embed the granules in some sort of filler material that kept its shape while you melted the surface?
I don't know...

I think that could work. Last I knew, ham radio operators could easily find 10 GHz equipment. Look at the Wikipedia entry on "skin depth", particularly the log-log graph in the "Examples" section. At 10 GHz you should have a good range of metals with skin depths well under 0.2 mm. Google search for "10 GHz" and "ham" and you might find information about the kind of equipment that's available.
