PLA or ABS - 3D Printing

[MossieOz]

Has anyone had any experience with the output from 3D printing, in PLA or ABS filaments?

For example:
What works best for a finished model?
Which are better for gluing?
Which provide a better paint finish?

What
I'm looking at is considering a new service to produce limited custom
3D printed objects for builders. The resolution would be 100 microns,
but may be better with experimentation.

This is not to undercut
any current provider, but to provide a one off service, that part you
need that is just too hard to scratch build or replica a number of items
the same.

There are some number crunching to be done, on costs
and prices, but I should be able to go under commercial printing costs,
but I'm not be able to match 16 microns that some services provide.
