RE: [rp-ml] min wall for SLA/SLS

Brett, we run an EOS laser sintering machine with PrimePart nylon
(unfilled), but I would guess our experience very comparable to 3D

If your floor is perpendicular to the laser, we can build a floor about
.013 thick (makes a nice living hinge). If you turn the floor so it is
in line with the laser, it will build about .026 due to effective beam
diameter of the laser.

Regards, Bob

I was wondering what the minimum, buildable short wall (2-3cm) thickness
(that people have been able to achieve) is for the following materials.
I would imagine that there would be variance in that figure, based on
the build direction, specific machine beam width etc, but any info would
be appreciated. Also, if you've ever bonded that material with epoxy I'd
love to hear your experience.
