Yes, you can! Printing more than one mini or piece at a time can save you much time, using the available build space more efficiently.
To do so, you can use the Lychee slicer, and organize the files in your build plate by moving them around. You should pay attention if the program shows any parts in red, as it’s a sign they’ll fail. However, it’s OK to cut parts of the raft if there are no supports attached to them.
Finally, make sure your printing settings are dialed correctly, since you’re going to waste much more resin if you have a failure.
