Alloy Enterprises, a startup backed by Lockheed Martin and Robert Downey Jr.’s venture fund, is developing 3D printing technology for aluminum, a key material used in a multitude of sectors including the emerging electric vehicle (EV) industry. In response to increasing demand for electrification, the company is hoping to reduce emissions and waste through its innovative approach. Recently, Alloy Enterprises raised $26 million in a Series A funding round which pushed its total funding to $37 million, with contributions from investors such as Piva Capital, MassMutual Catalyst Fund, and aerospace company Lockheed Martin.
The startup, based in Burlington, Massachusetts, is focusing on a 3D-printing technology that combines laser-cutting techniques and “diffusive bonding” to produce components for various sectors including automotive and heavy machinery. Its unique process uses coiled sheets of aluminum as raw input, differing from the traditional 3D metal printing methods which require powders, and thus reducing material costs significantly at higher production volumes. With the influx of new funds, Alloy Enterprises aims to expand production and qualify its systems for increased volume production.
The impact of Alloy’s production process on carbon footprints depends on the source of the aluminum coils used. As per the International Energy Agency, primary aluminum production is responsible for around 3% of global industrial emissions annually. While Alloy’s production process addresses only a small portion of emission reduction potential, its efforts align with ongoing initiatives to lower the carbon footprint of primary aluminum production and reinforce its status as an “infinitely recyclable” material. The startup’s technology also provides potential cost benefits to manufacturers in the EV, industrial and heavy machinery sectors by offering more efficient production processes.
