Elbow Details

Since there are so many arms of the FX-7, I decided that the most economical way to produce all of the pieces was to 3D print them and then cast them.

I thought I'd start with something small. I made the elbow details in 3D, using reference pictures I found online of the FX-7 when it was on display at the Smithsonian, I believe.

I printed out 4, coated them with XTC-3D to make them smoother, then make a mold using Smooth-On OOMOO 25. Once the mold was made I did a test cast using Smoothcast 300.

I was very happy with the results, but I think I will be more generous with the XTC-3D on the printed pieces in the future since I could still see some of the striping from the 3D print.
