Rapid prototyping uses three-dimensional (3D) computer aided design to quickly fabricate a part or, alternatively, a sand mold for casting a part from metal. Currently there are many limitations with ...

Seems like most of the metal casting projects we feature are aluminum in sand molds, though, so it’s refreshing to see a casting project using silicone molds to cast low-melting point metals.

The print is carefully sanded down and post-processed to be highly smooth, so that it doesn’t spoil the mold when its removed for the casting process. From there, a sand casting mold is built ...

Dive into the world of metal casting with this detailed look at the aluminum sand casting process. Watch as molten aluminum is carefully poured into sand molds, where it solidifies into ...
