I'm thinking of having some components made. 3d printing (hack, spit) may be a possible solution.

Is there available technology to print 1-5mm extrusion? I'd guess this would be faster, thus cheaper than popular modern 3d printing. I don't mind the lines but wish to avoid cracking joins and too much stringyness.

Can anyone point me towards machine or outfit? Could a cheap regular machine be easily altered for larger extrusion?

I'm not looking for fine detail, just various basic forms 2-3 inches-ish. Pobably abs, unless hips.

1mm is usually the largest size nozzle available. If you find a printer that meets you needs, I would advise using PLA rather than ABS, it's much easier to work with.

How many are you talking about?

Do they need to be strong? If not you can use SLA printing, which gets rid of all lines and stringiness.

If this is for a small number of items DM me…

100+ copies. It does need to be strong, hence thicker extrusion. Low cost is the main thing. Speed also a factor. Abs preferred.

Trying to avoid injection due to usual tooling cost issues.

You can't do injection for a hundred units.

Modern PLA is pretty much as strong as ABS. Watch some CNC Kitchen on YouTube.
