My first attempt to make a mold of my ring finger was to make an algeonate negative, then pour in plaster.

My whole hand came out pretty decent, there weren’t any bubbles or so, but the nails weren’t very well defined. While I was breaking the plaster out of the algeonate, some of my fingers snapped off, but fortunately my ring finger survived.

Next, I decided to make a plastic mold of my finger, and I used the same process of making an algeonate negative, then filled in the plastic solution. I chose to use the cast 65D type, and because it was so expensive, I only poured it in my fourth finger negative to save material. I used plexiglass in order to ensure it didn’t spill over to the other fingers while also getting a mold of the knuckle.

This is my rough initial product before any post processing. I guess the plexiglass wasn’t embedded far enough into the algeonate and the plastic spilled over to my pinky finger.

To postprocess both my plaster and plastic fingers, I used a dremel to sand down the rough edges. For the plaster, I had to separate my fourth finger from the rest of my hand and then dremel the bottom so it could stand properly. For the plastic, the bottom was already pretty flat, so I only had to sand down the edges to make it look smoother. These are my two final products, the plaster is on the right and the plastic is on the left. Both are mold of my fourth finger, but the plaster one is taller because there was more material on the bottom.
