Unreasonable Rocket's 3d Printed Rocket Engine Takes Flight!

My two passions are Rocketry and 3d Printing.  Paul Breed has combined the 2 in his test flight of a 3d printed stainless steel rocket engine. 

To my knowledge this is the 1st successfully flown liquid fueled 3d printed rocket engine.

Paul Breed has a wonderful blog over at, you should really check it out, a lot of his issues with his 3d printed Rocket engine dovetail with issues we will run into as we use our parts for higher temp/pressure applications.

Very cool, especially given that your rocket landed almost exactly on the pad! Nice flight.
I was there and filmed it.

He did not fly the printed engine. The rocket you saw fly was a solid for testing GPS systems. The printed engine was run for 2 minutes on a stand.
So could you point us at some links in the blog that actually talk about the printed engine?
You have to go back to 2010 to see some of the pictures of the printed engine. Try July 2010 and September 2010 to start.
3d printing + rockets
