Additive Manufactured Aerospike Rocket - Static Test Firing

We built a rocket engine using additive manufacturing (metal 3D printing). Completely new design from concept to test firing in 4 months.
The engine is a complex multi-chamber aerospike design
Additively manufactured with selective laser melting using the full build volume of an EOS M280
Built from Hasteloy X; a high strength nickel based superalloy
Fuel: compressed natural gas (methane); oxidiser: compressed oxygen
Design thrust of 4kN or about 1,000 pounds.
A collaborative project of Amaero Engineering and NextAero, supported by Monash University and Woodside Energy.
