Yes
STL is very simple that's why 3D Systems selected it in the first place. but
we need to move on.

Yes
some software vendors CAN'T get it right, why do you think we need to check
and correct them using such programmes as 3Data Expert (Deskartes), Magics
(Materialise), Trifix (Delcam) and 3Dverify (3D Systems).

I would like to build parts on my SLA machine with layers of 0.02mm but the
software will only let me do 0.025mm. I have already had my vertical surface
roughness samples confirmed by an independent source (De Mountfort
University) as being better than 5 microns

Average RA values 3.56512 mM (Microns)

What I want to eliminate from my SLA models is the indications of laser
fluctuations/positioning errors, STL mesh patterning, jagged contour
striations and geometry deviations. All very slight but detracting from the
preferred output required.

So RP vendors should give the users the chance to operate their expensive
systems, built with high specifications, the ability to produce high quality
models and not be stifled by inadequate software limitations.

(similar to the car advert ....... Inadequate car? should be driving ???,
and not using STL!)

(PS is Wife 1.0 a virus that most males seem to get infected with?)

(PPS I would gladly help a software vendor in finding the solutions that
would improve the problems we have to put up with as part of someone's idea
of process limitations)
