Skuld has three patents pending on their new manufacturing process called additive manufacturing evaporative casting (AMEC). AMEC joins together the capabilities of lost foam casting (a type of precision investment casting) and 3D printing of polymers. Compared with alternative AM processes, AMEC is faster, is capable of creating larger parts with precision tolerances, is less expensive, and has known microstructures for ease of part qualification. A basic proof of concept has been shown in a variety of metals. Skuld recently completed a US Department of Defense Small Business Innovation Research project to demonstrate AMEC in aluminum and an America Makes project to develop the process for Inconel alloys. Skuld is also working on several commercial prototypes. In September 2023 they are launching a machine, Lightning Metal™, to allow others to utilize the process.
