I have the same problems with Duraform PA. I built a structure with open
porosity and rests of the powder stuck in the pores in the middle of the
built, which I can't reach with the blaster.
I tried an ultrasonic cleaner, but it didn't help much as the medium (here
water) is soaked by the powder which seemed then to stick even more to the
It's not that it really needs force to be removed, but it does not fall of
by itself or by slamming the part onto the table.
I am open for other suggestions.

I am currently using a bead blaster to clean the excess Duraform GF out of
my parts, but I am having trouble with the hard to reach areas and blind
holes. I was wondering if there were any other methods used to clean SLS RP
parts. Do ultrasonic cleaners work? Any input or suggestions would be
greatly appreciated.
