Assignment for week 12 Molding & Casting


For this project I really wanted to use the opportunity to learn new ways of making molds and find new materials to work with.

I was eagerly waiting for this week because I feel this assignment cover the most important part of my final project.Because, While working on prosthesis I came up with a bigest problem.

After a lot of efforts I was able to get some movement of the fingers but , now the task was to fit the hand to the amputee. I tried several ways to fix the hand but was getting some difficulty in fixing the hand.So, I decided to make a socket fitting for this I took the amputee and did 3D scannig of his hand but was getting several problems while scanning every single part.

So, I decided to make a mold of the amputee hand and from this mold I can make a socket fitting which can best fit to the amputee.

So this is how I made a Mold:

Step 1 : First I took some butter and applied it on the part of the amputee hand of which I want to make a Mold
