Molding and casting

This weeks assignment was to create a mold and make a cast out of the mold

          I started this by making simple 3D sketch using the AutoCAD program. After getting my 3D drawing, I saved it as an STL file and then using the fab module in the STL to RML mode. I openned my STL file, checked the size to make sure it is the rigth size and then made a PNG. From the PNG, I then made the part by first sellecting the tool path parameters for rough cutting after which I made tool path for smoot cauuting. I then calculated the tool path and then with my material (wax) in place, I sent the command for the catting process for each face.

          I then use the wax mold to create a flex mold which is then used to cast my odject.
