AcademicWe are SEDS UCSD, the undergrads that designed, tested, and launched one of the first 3D printed rocket engines. Ask us anything!

Who we are: A multi-disciplinary, entirely undergrad group looking to advance the new space movement. We seek to make getting to space cheaper and easier than ever before through our research in 3D printing and propulsion technologies.

If you'd like to help us keep innovating and growing the next generation of aerospace leaders, we encourage you to contribute to our Triteia project and help us get to the moon!
Thanks for your time and ad astra per aspera, The SEDS UCSD Team
Our rocket thrusters Callan and Vulcan-1 are printed through DMLS (Direct Metal Laser Sintering) in Inconel 718, which is a chromium-nickel alloy. Our first rocket engine, Tri-D, was printed in cobalt chromium.
How and when did your organization originate?
Also, as an aspiring accountant, I'm interested in how you manage finances for your projects.
We started in 2012 as a group of friends who wanted to tackle the challenge of using additive manufacturing to create a better liquid rocket engine. The last of that original group graduated just last year and are now working in the industry. We've continued researching and creating 3D printed engines, and as interest in our student org has grown, so have our projects – from the single Tri-D engine project to our multiple current projects and nearly 90 members.
We have a business team that takes care of finances, graphics, and marketing. Like the way we recruit engineering majors for real-world experience, we recruit economics and management science majors to manage our finances. We are mostly funded by sponsorships, so some of it is negotiating those then making sure our parts procurement is within the budget. Our business team has also been working on crowdfunding for our cube satellite project, Triteia, so we can purchase some of the crucial parts!
do you own the printer or do you outsource the printing?
What printer do you use?
Any thoughts on 3D printed hybrid rocket engines? (printed part as fuel)
Hi! We don't own a printer, nor do we have access to a metal 3D printer on campus. Our sponsors, GPI Prototype (Vulcan) and MTI (Triteia) print iterations at their locations, then send them to us so we can test them. As for thoughts on hybrid rocket engines, we're putting the question out to some our team – we'll update when we get some answers!
Do you think ordering TapX's popcorn chicken is a questionable decision?
If you want to order it, we'll support you all the way!
A lot of us are looking to work at space companies, like SpaceX or Virgin Galactic, or at places like NASA. Some of us are looking to go into similar industries, like robotics or AI, or even create start-ups.
First off, this sounds really fun. Second, how does one join SEDS?
It's one of the best experiences we've ever had! SEDS UCSD accepts applications from current UCSD students during our recruitment periods. We post all information about recruitment events and application deadlines on our Facebook page, so be sure to keep up with us there!
