3d printed sands
Thanks to 3D printing solutions we can perform “prints” of digital cores directly from 3D STL files. These sacrificial details are perfect for leaving complex cavities in metal castings made in the most common foundry alloys such as aluminum, cast iron and others.
The technique allows the creation of very complex and slender figures obtained through a progressive stratification of inert material bound by a two-component resin system. The construction does not need supporting materials, so you can make really elaborate figures or very complex groups that with other solutions should be separated into individual figures then individually resolved.
