Hi Candice -
The service bureau that we use for our Wax Jet Printing (Sanders process)
consistently supplies models with features as small as 0.129mm.
I hope that others with real world experience, will contribute their
experience to this listing. It will prove useful to us in designing for the
various commercial processes.
