Think it could handle small spur gears? I fix model locomotives, and
I've seen quite a few of these split. Sometimes I can find a replacement
gear, but more often than not, no dice.
Cost-wise, I'm sure right now the 3D printed gear would make a $10 acetyl
replacement look cheap.

We're talking a range of 1/8 - 5/8" diameter. Somewhere around 10-18T on
average, based on the few I've measured.
Some gears have spacers integrated, which might make things even harder.

I have a vertical increment of 70 microns. I normally use 200 or even 300.
.125" is large. But yes I build larger things at less resolution like
200. Consider the time - 3x time for what smoothness.

I have this one.
Now for some really fine machines - the Website of the company that
sells through cubify as their portal.

What you need to have is a 3-D scanner to scan in the part and then
clean up the scan and print one.
Odds are the real precision models might be to high.

The various companies are trying for niche areas. This looks like a
viable one.
I have a pro grade 3D and it prints in three types of plastic. The
company makes candy/cake.. plastic, Metal (serious metal), and the
largest ones make car front ends. And then there are the 65K colors
in the expensive ones - print a 3D rainbow or flowers... color 3-d
heads. The high volume ones are hearing aids.

I like bowed and twisted wood. Just yesterday I turned a carving mallet
from a piece of firewood. Just grabbed a random piece from a cord of
red oak. It's always fun to show someone the wood before and after.
3d printers are useful and I'd like to have one but they are
pricey. Nanotech is the new direction though. Assembling things
at the nano level is hard for most to comprehend but it's here now.
You won't find one at harbor freight.

The part could be measured by hand. Also check thingverse. I found
parts on there that were perfect with no mods.

I think this is possible but not certain. How small? What's diameter?

The plastic is cheap. Check thingverse and sites like that for
designs that others have already made. I found some parts for
consumer products that were perfect when 3d printed and needed
no modifications.
Often times someone with a 3d printer will be more than happy
to print something out if you provide the model. You may have
to measure the part.

Making a plastic hammer is a viable niche? Or you mean something else?

There are 3d laser printers now too. Material is $1/kilogram.

Funny how many times the article says maker bot. It reads like an
ad.
I like this one as it's cheaper than most. It does require some
hands-on assembly. But I like it for the unique gantry.

I think 3d printers can do that. Check with someone that has one.
Ask on seemecnc forums or the like.
I'd guess that you'll find parts models on thingverse or the like.
