I’ve tried the acetone smoothing a some samples. First results are encouraging. On “micro” scale the surface seems smooths as it get’s shinny. On “macro” scale not much smoothing happened. I’m trying some samples with different times and temperatures.
A different filament material will not solve the micro cracks and gaps. Food safe is only interesting when there is a long contact between the material and food. I’m interested in cleaning the object not putting it for a long time in contact with food.
I work for a print shop and it’s what we do to any printed part we want smooth is a 2 part resin but you can also use fiberglass resin but it’s a bit more messy and generally something we only use on large parts.
The result. The part put into a plastic container, then covered with “Poly-clear” and sealed with a lid, overnight. The product is water-based, non-toxic, no smell etc. The “plasticizers” penetrate the part to dramatically increase translucency, gloss and strength of the part.
