Hi, what is the highest resolution that can be printed in plastic? I am new to 3D printing so please don’t ask me too technical questions :slight_smile: I would like to 3D print a plastic piece with holes in it. I need these holes to be extremely small, in the order of a tenth of a millimeter. Is this something that can be done with current 3D printing technology?

Thank you.

Probably can be done but you may need to drill the holes out to clean them up or size them correctly. It would really just take trying it.

FDM type printing (filament) may have a hard time depending on the printer and nozzle size.

If you’re looking for very small holes, your only chance would be to do it in resin. The feature size (x/y resolution) on my resin printer is 0.047mm, however, getting a clear hole through a part that small is next to impossible. I’ve printed some pretty tiny parts that required holes on the order of 0.6-0.8mm and that took considerable time to tweak layer cure times and then post-processing the pieces (alcohol wash to clear out left-over resin in the holes, etc).

I’m curious about what kind of part you have that needs holes that small.
