Sanding/polishing down Dental/biocompatible resin for an ultra smooth finish


#1

Hi all,

We use the dental and biocompatible resin for a lot of our cell culture lab work for certain reactors. The current resolution (50 microns) is too big as our cells are around 10-25 microns in size. I was wondering if I sand the prints down with grits moving towards a high grit (3000+), will I be able to remove the layer discrepancies and almost achieve an ultra smooth finish?

I attached a short sketch to illustrate what I’m asking about (please excuse the atrocious paint job).

Hi, it will be a lot of work, but people have done it, for example for manufacturing lenses out of clear resin. As of how to do it exactly, these links could give you an idea:
