Students Test Fire 3D Printed Rocket Engine | Video

UC San Diego became the first university to design, print and test an 'additively-manufactured 'rocket engine. It was printed from Cobalt Chromium. The students were part of UCSD's chapter of Students for the Exploration and Development of Space (SEDS)

That was actually our ignition system! Nothing fell apart from the engine itself.

[@skeletal531oblivion]

We used SolidWorks and a program called RPA, Rocket Propulsion Analysis

I friggin love solidworks, one of the best programs ever!

[@skeletal531oblivion]

Due to the nature of our static fire system we had to shut off out Liquid Oxygen supply first and then left our RP-1 valve open to cool then engine after our test concluded. That is why it looks like a bunch of flames shot out afterwards. It was just extra RP-1 to cool the engine.

That is a great test and huge step in future travel possibly to make parts lighter and cheaper to build the crafts needed for long time travel!!!!!

Thats called flaming out. The fire inside the pressure chamber goes out, maybe due to an inequality of fuel / oxidizer. The rest fuel / oxidizer is just pushed outside where it gets ignited by the still existing heat.

I was actually planning on doing this! now i know it's possible.

[@TyPeRHSDT]

so cool.

[@karlharvymarx2650]

That looked really good. What software did you use to design it?

[@Didzeee]

from rocket launches i've seen i'd say it's when it runs out of fuel

[@yekid56duce]

was this done in mohave desert ? Have you Guys thought about using LOX and Propylene ?

[@mastersogood]

great

[@rizendell]

looked like it blew its guts out on the first run, notice the metal that flew out at 0:07.

[@vazaubaev]

What happends in 0:10?

[@snuffying]

it kinda worked for 2 3 seconds

[@TheSilencedMajority]

It goes bursaries
