Colorado-based company Agile Space Propulsion was born from the expertise of Daudi Barnes, who has been working in the spacecraft propulsion industry since 1998. Agile Space Propulsion has a specific goal: to design and manufacture rocket engines using 3D printing technology. In particular, Barnes wants to develop thrusters, the small maneuvering engines used in rockets. According to Barnes, as rockets get cheaper, there is an increasing need for thrusters, and the miniaturization of electronics is spurring demand for more space vehicles for a variety of purposes.
Rocket launches have been downsizing and becoming lighter and cheaper, partially thanks to 3D printing, which enables complex parts to be made in fewer components, or even in a single component. It also allows for a great deal of lightweighting.
Agile Space Propulsion has already developed a 100-pound thruster and is currently working on a five-pound one. Barnes points to the use of 3D printing in much of aerospace, for both small and large engines.
