Cali’s fingers!

Catching up on assignments after a week out of town, I first completed the molding and casting of my fingers. For time and material’s sake, I did two different fingers in the same cup of alginate.

I first weighed the alginate and water, using the ratio provided in the instructions. I then mixed both until it was smooth with no clumps, mixing continuously with a popsicle stick.

After around 3 minutes, the mixture started to thicken up, at which point I stuck my fingers in. Five more minutes later, the alginate had solidified around my fingers, and I wriggled them out, revealing a mold of my left pointer and middle fingers.

Directly after, I measured the Rockite to water ratio, per the instructions, and again mixed with the same popsicle stick until smooth. Then, I poured half into one finger mold, half into the other. Using the provided 3D printed jig, I inserted two screws into each finger, securing the jig and screws with tape as well.

When I came back the next day, I de-molded the fingers, producing two different wall finger hooks!

For post-processing, I sanded some of the imperfections away and spray painted with a clear coat! I think if I had more time currently (and more sleep) I would’ve loved to complete the advanced assignment and make something super cool out of a mold.
