A 3D printing Facebook group I belong to recently had an interesting post. Here are all the minis a user was able to print (28mm scale) from 1,000g of resin after culling support and the following failed prints:
-Baby Groot Apple Watch charging station
-small modular inn
-about a dozen minis
He estimates about $145 worth of RPG minis for $30 of resin and his time. Unclear how much more in IPA for cleaning.
