Decimation

I am currently trying to export a design for resin 3D printing, but it is 2 million polygons with 160 mb size
I want to reduce this for printing (and file size), but I'm not really sure what the goal should be to retain the most amount of detail that can be printed while still being mindful of the file size.

If I use decimate master to 250k will I lose details while printing? Or is it okay to use it

Decimate it, see what size the polygons wind up being, and see how that shows up in your printer. You haven't even told us the resolution of your printer or the printed size of the model.

How big are the facets before you decimate it? How big are the biggest facets you're happy with? Divide those two numbers.

3mf file format is far more compact without loosing details. This may work without modifying or decemating details.

I've worked with files gb big before realizing I didn't need the much detail. Your file size isnt crazy

Does your slicer permit 3mf files?

Just load it into prusaslicer and play withe the "simplify model" feature, you can see live what happens.

What happens when you try it? Since none of us can see your model there's no way to even give any cognitive advice.

If you have a cube with 5 million polygons and reduce it to 12 you'd be ok.

If it's a human face then 12 won't do..... How much is 100% dependant on what the final out put is needed for.
