The fumes from a resin printer represent a serious health risk. One should have substantial airflow to cause the fumes to exit the work area, and one should also consider a respirator that handles VOC thoroughly. You can get incredible detail with a resin printer compared to an FFF printer (FDM is a trademark).

Small is a relative term. If you require detail levels of smaller than 0.400 millimeters, it would be resin, but upwards of that level, FFF will do you well.

Consider to seek out test prints on reddit to see what others can generate from your models. It may cost a few dollars but you'll save in the long run if you find the hard way your selection won't work for you .
