RE: New Resin from 3D Systems

For SL 5410, can anyone confirm the need to use solvent to clean the parts
prior to post curing in PCA??

If there is a need for solvent, with the higher humidity resistance claimed
for this material, can water be used for final rinsing of solvent before
post curing??
