3D Printing with Salt

An American company, named “Emerging Objects” where the first to perform 3D printing using salt as a printing material. The product of this process is a pavilion inspired by the igloos of the Inuit. Being the first to perform this method, the whole process is like one big science experiment, with the goal of producing a large-scale structure, while remaining relatively lightweight.

Being located in San Francisco Bay, works to their advantage, as the salt can be locally sourced from the bay. It’s obtained from the 109 year-old salt crystallization ponds within Redwood City. The crystals within these ponds are 8-12 inches in length, which makes for good harvesting.

The benefit in using salt compared to commercial materials, for one it’s renewable and secondly it’s inexpensive.

The structure uses a total number of 336 unique translucent panels, which allows for subtle lighting of the internal space. The translucency is a product of the fabrication process, with the added property of salt being naturally translucent.
