I love Trevor’s enthusiasm, talking about the Aerospike in this new video from Titan’s of CNC, where he prints the rocket engine out of Titanium. I must say though that as an Aerospace Engineer, I cringe on the material choice: Titanium has a very low thermal conductivity and therefore would not be a favorable pick for a engine type that tends to overheat easily. Never mind, it is beautifully done!
