Ignus-II

Printed March 2018
Material Inconel 718
Thrust Approx. 800lbs
Fuel Liquid Oxygen & Kerosene RP-1
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.

Ignus-II was printed by i3D MFG.

Callan

Printed October 2016
Material Inconel 718
Thrust 1lb or 4N
Diameter 0.5 inches
Height 1.6 inches
Fuel Hydrogen Peroxide
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.

Ignus-I

Printed March 2015
Material Inconel 718
Thrust 750lbs or 3336N
Diameter 8 inches
Height 10 inches
Fuel Liquid Oxygen & Kerosene RP-1
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-1 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.

Tri-D

Printed October 2013
Material Cobalt Chromium
Thrust 250lbs or 1112N
Diameter 3.5 inches
Height 7 inches
Fuel Liquid Oxygen &Kerosene RP-1
Tri-D is the first engine designd by SEDS at UCSD. It is the first 3D printed rocket engine by a student organization.

Tri-D was developed with the help of NASA's Marshall Flight Center and printed with by GPI Prototype and Manufacturing Services. It was meticulously designed to prevent overheating by burning fuel away from the walls, utilizing a regenerative cooling jacket, and maintaining layer of relatively cool gases
