Like many projects, a combination of techniques yields the best result, and in this case we get to see 3d printing, sand casting, lost PLA casting, lathe turning, milling, and even some good old ...

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 ...

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 ...

The proposed facility aims to meet the sand casting demands in the growing aerospace industry. This increased sand-casting capacity would support both commercial and defence sectors. Currently ...
