Using the pewter casting equipment in the downstairs metalworking area, Eugene and I cast a couple of Darth Vader heads into an MDF mould that we cut on the Superbox CNC Router.
Design
The mould design was taken from a design made by Timothy Zorn on GrabCAD. I think it was designed with 3D printing in mind because there were some very sharp corners on the model that can't be machined with milling cutters. None the less, we used it anyway! We made a couple of modifications to the model:
- We scaled the depth down in z by about 40% so that it would be millable with the short small diameter cutters I had.
- We moved the sprue to the opposite side of the mould
- We added some air venting to the mould

Manufacture
The mould was cut into MDF using a 3.175mm tool and a 1.5mm ball nose tool on the Superbox CNC Router.
After the mould was finished, it was trimmed out of the stock using a band saw and the cavity surfaces were brushed with a small amount of graphite taken from a pencil.
