A while back we had a questionable print on our Form 3 with grey pro resin, so we decided to change out the tank. To ensure a fresh start, we followed the instructions for cleaning up after a failed print and tried to pass the grey pro resin through a filter with a vacuum assist. We noticed a thick layer of very fine particulate immediately clog the filter, making it impossibly slow, so we gave up and disposed of the resin in the old tank. At the time, we chalked it up to having some questionable prints.
I’m wondering now though if the grey pro resin is designed to have particles suspended within it. Does anyone know if that is the case? What is your advice on transferring grey pro resin to a new tank, especially after questionable prints?
