The Clemson University Foundry (CUF) is
a Z-Corp
Gold level metal casting partner, which means that we have the means
to both print molds directly from 3D solid model files and to cast parts.
The Z-Cast refractory material is limited to non-ferrous alloys because
of its temperature capability, so the CUF also uses patterns printed on
the Z-printer to prepare resin bonded precision sand molds. These molds
can be used for gray iron and other high temperature alloys. |

| Sequence of steps leading to casting of 4 gray iron parts
in a resin bonded sand mold. The sequence shows the CAD model used to create
the Z-printed pattern boxes. Next are melting and pouring, followed by the
as-cast parts in the mold.The final image shows the parts still attached
to the runners and sprue after sand blasting. |
