I am using Clear resin for a prototype. The design has very small pores order of 0.1mm. Since the resin is very viscous, it tends to get stuck in the holes. What is the best way to solve this problem. I have tried printing both with and without supports, even though with supports was better but not perfect. Even washing with IPA for 10 minutes is not helping much. Would appreciate any suggestions for same. Additionally what is the viscosity of the resin before curing? And what is the heat deflection temperature of rein pre curing? Will heating the resin help solve this issue?
What I would recommend for this is that after the usual wash cycle, use a syringe with IPA to manually flush out small channels or holes in the part.
I was able to find some viscosity data on our resins, but not specifically for BioMed Clear. The HDT is listed on the datasheet, although this is for the post-cured, solid resin. If you do specifically need to know these properties, the best way to check would be to create a support case so we could place a request with our Materials team.
Lastly, I’m not sure whether heating the part would help. It does make sense intuitively as the resin would flow more easily. If you do end up trying this, please keep us posted with the results.
I do this all the time, wash for 10 min, Pump IPA through the holes using syringe with needle and wash again for 5 - 10 min
