Ignus-II is the second iteration of the Ignus-I engine, the first 3D-printed engine launched by a student organization. Ignus-II builds upon our research and data gathered and features many improvements to optimize efficiency.

Callan is a mono-propellant thruster designed for our Triteia CubeSat. It is SEDS UCSD’s third 3D-printed engine. By running hydrogen peroxide through it’s nickel-silver catalyst bed, decomposition of the hydrogen peroxide occurs and heat is generated. The heat is channeled through a nozzle, providing thrust.

Callan and subsequent revisions were cold-flowed at Open Source Maker Labs in Vista, CA before being hot-fired at Purdue University.

The Vulcan engine and Ignus injector plate is SEDS UCSD’s 2nd 3D-printed engine and was designed to be bigger and more powerful than Tri-D.

Following the success of Tri-D, Ignus-I was desgined to push the boundaries of 3D printing with intricate and unique shapes, paths, and techniques.

Ignus-I was launched on the Vulcan-I rocket in May 2016, becoming the 3D-printed engine launched of an undergraduate organization.

The engine will be on display at the California Science Center in Los Angeles, CA upon completion of the Samuel Oschin Pavilion.
