By 2017, a 3D printed rocket engine had successfully launched a rocket to space, when on 25 May 2017 an Electron rocket launched to space from New Zealand that was the first to be powered by a main stage rocket "engine made almost entirely using 3D printing." [3] The Electron's first successful orbital launch was on 21 January 2018. [4]
The aerospike engine is a type of rocket engine that maintains its aerodynamic efficiency across a wide range of altitudes. [1] It belongs to the class of altitude compensating nozzle engines. [ 2 ] Aerospike engines were proposed for many single-stage-to-orbit (SSTO) designs.
The Curie engine, named after Polish scientist Marie Skłodowska–Curie, is a small liquid-propellant rocket engine designed to release "small satellites from the constricting parameters of primary payload orbits and enables them to fully reach their potential, including faster deployment of small satellite constellations and better positioning for Earth imaging".

Relativity Space is disrupting the traditional aerospace industry by manufacturing the first autonomous rocket factory using 3D printed rockets.
The engine is mostly 3D printed, [7] with some of the biggest 3D printers in the world. The rationale for the cycle change from the original gas generator was that they could not get the performance they needed through all the throttle points that a reusable rocket needs, without pushing the turbine temperature and other factors beyond their ...
It was announced in May 2014 that the flight-qualified version of the SuperDraco engine is the first [clarification needed] fully 3D printed rocket engine. In particular, the engine combustion chamber is printed of Inconel , an alloy of nickel and iron, using a process of direct metal laser sintering , and operates at a chamber pressure 6,900 ...
The engine is planned to have the following features: Methane–oxygen propellant. Extensive use of metal 3D printing (up to 50% of the engine). [3] Open gas-generator cycle. [5] 980 kN of thrust (~100 tonnes), variable from 30% to 110% thrust. [5] 100 bar (10,000 kPa) chamber pressure. [5] 360 s specific impulse (I sp). [citation needed]
The Aeon 1 rocket engine is designed to produce 23,000 pounds-force (100,000 N) at sea level and 25,400 pounds-force (113,000 N) in a vacuum. The engine is powered by liquid natural gas (LNG) and liquid oxygen (LOX). It is made out of a proprietary 3D-printed alloy.
