For this week, I modeled a turtle for molding and casting. I used rhino for modeling and exported stl.
After creating the turtle, I split it into two parts in order to create two molding pieces.
Milling took too much time. I reserved 2 hours for this purpose, which eventually ended up being 6 hours just for milling.
I made several attempts for milling. In one of them, in the finishing phase coordinates massed up and it drill through my object.
In an other attempt, since I did not tight the set screws enough, milling head pull off from the machine again drilling trough my object.
In the end I was only able to create upper part, and keep the lower part for another day.
Wax molding.
It take a little time to remove bubbles from rubber, I mixed the parts in a wrong way which leaded a lot of bubbles inside it. Anyway,
I was able to remove them by shaking and vibrating it.
Final rubber casting.
Since my model was designed for two pieces, I had unnecessary vantilation and pouring channels in my model.
I used dry stone mix for my turtle.
The half turtle.
