With 3D printing solutions, we can make “prints” of foundry molds directly from 3D STL files. These sacrificial parts are perfect for leaving complex cavities within metal castings made from the most common alloys of foundry aluminum, cast iron and others.
The technique allows the digital design of even very complex and slender figures obtained by progressive layering of inert material bound by a two-component resin system. The construction does not require supporting materials so you can make really elaborate figures or very complex groups that with other solutions would have to be separated into the individual figures then solved individually.
Based on silica sand and furan binder (identical to the “cold-box” product), they are perfectly compatible with all foundry processes for aluminum, cast iron, bronze and brass.
