In March, the Relativity Space Terran 1 rocket lit up the night sky as it launched from Cape Canaveral Space Force Station in Florida. This was the first launch of a test rocket made entirely from 3D-printed parts, measuring 100 feet tall and 7.5 feet wide. A form of additive manufacturing, 3D printing is a key technology for enhancing capabilities and reducing cost. Terran 1 included nine additively manufactured engines made of an innovative copper alloy, which experienced temperatures approaching 6,000 degrees Fahrenheit.
Created at NASA’s Glenn Research Center in Cleveland under the agency’s Game Changing Development program, this family of copper-based alloys known as Glenn Research Copper, or GRCop, are designed for use in combustion chambers of high performance rocket engines. A combination of copper, chromium, and niobium, GRCop is optimized for high strength, high thermal conductivity, high creep resistance – which allows more stress and strain in high temperature applications – and good low cycle fatigue -– which prevents material failures –above 900 degrees Farenheit. They tolerate temperatures up to 40% higher than traditional copper alloys, which leads to higher performance components and reusability.

Future lunar landers might come equipped with 3D printed rocket engine parts that help bring down overall manufacturing costs and reduce production time. NASA is investing in advanced manufacturing – one of five industries of the future – to make it possible.
Through a series of hot-fire tests in November, NASA demonstrated that two additively manufactured engine components – a copper alloy combustion chamber and nozzle made of a high-strength hydrogen resistant alloy – could withstand the same extreme combustion environments that traditionally manufactured metal structures experience in flight.

Just in case you want to know, 3D printed (additive manufacturing) in metal using powder bed selective laser melting (SLM), teeth and dental plates made by Renishaw.
The widespread commercial adoption of additive manufacturing technologies, commonly known as 3D printing, is no surprise to design engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama whose research created stronger, lighter weight materials and new manufacturing processes to make rocket parts.
NASA’s RAMPT (Rapid Analysis and Manufacturing Propulsion Technology) project is on the cutting-edge of additive manufacturing – helping the agency and industry produce new alloys and additively manufactured parts, commonly referred to as 3D printing, according to Paul Gradl, the project’s co-principal investigator at NASA Marshall.
This image shows a hot-fire test at NASA’s Marshall Space Flight Center in Huntsville, Alabama. This 2,000-pound-force coupled thrust chamber assembly features a NASA HR-1 alloy nozzle. Manufacturing the hardware requires the directed energy deposition process with composite-overwrap for structural support, reducing weight by 40%. Industry, academic, and government partners are working with RAMPT engineers at Marshall and other NASA field centers to advance this revolutionary technology.

In the fall of 2023, NASA hot fire tested an aluminum-based, 3D-printed rocket engine nozzle. What made the event remarkable is that aluminum isn’t typically used for additive manufacturing because the process causes it to crack, and it isn’t used in rocket engines due to its low melting point. Yet the test was a success.
The new possibility of printed aluminum engine parts will mean significant savings for NASA in terms of time, money, and, most importantly, the weight of future spacecraft. And Elementum 3D Inc., a partner on the project, is now bringing the benefits of that technology to its customers, including not only rocket engine manufacturers but also makers of race cars, lighting fixtures, computer chips, and more
In this image, a laser powder directed energy deposition (LP-DED) 3D printer at RPM Innovations’ facility additively manufactures a large-scale aerospike rocket engine nozzle from one of Elementum 3D’s specialized, 3D-printable aluminum alloys.

Engineers just completed hot-fire testing with two 3-D printed rocket injectors. Certain features of the rocket components were designed to increase rocket engine performance. The injector mixed liquid oxygen and gaseous hydrogen together, which combusted at temperatures over 6,000 degrees Fahrenheit, producing more than 20,000 pounds of thrust.
The additive manufacturing process allowed rocket designers to create an injector with 40 individual spray elements, all printed as a single component rather than manufactured individually. The part was similar in size to injectors that power small rocket engines and similar in design to injectors for large engines, such as the RS-25 engine that will power NASA's Space Launch System (SLS) rocket, the heavy-lift, exploration class rocket under development to take humans beyond Earth orbit and to Mars.

NASA’s investment in a breakthrough superalloy developed for the extreme temperatures and harsh conditions of air and spaceflight is on the threshold of paying commercial dividends.
The agency is licensing its invention, dubbed “GRX-810,” to four American companies, a practice that benefits the United States economy as a return on investment of taxpayer dollars.
GRX-810 is a 3D-printable high-temperature material that will lead to stronger, more durable airplane and spacecraft parts that can withstand more punishment before reaching their breaking point.
In this image, the NASA insignia is 3D printed using the GRX-810 superalloy.

We do a lot of additive manufacturing (3D Printing) in plastics and metals at work. After a while the powder starting materials, having been through the machines a number of times, become “spent”, that is, they cannot be used for clients’ work any more. Colleagues asked if they could print something festive so the lead designer came up with a stable, Bethlehem style, complete with boxes, amphorae and even a dove cote and printed it in spent PA2200 nylon. The model is approximately 450 x 250 x 250mm and could be painted in acrylic colours.
An impressive use of recycled, waste material.
HAPPY HOLIDAYS
Engineers from NASA's Marshall Space Flight Center recently built and tested an additively manufactured – or 3D printed – rocket engine nozzle made of aluminum, making it lighter than conventional nozzles and setting the course for deep space flights that can carry more payloads. Meet NASA’s latest development under the Reactive Additive Manufacturing for the Fourth Industrial Revolution, or RAMFIRE, project.
In this image, the RAMFIRE nozzles complete hot fire testing at Marshall’s East test area using liquid oxygen and liquid hydrogen (orange/clear plume), as well as liquid oxygen and liquid methane (blue plume) fuel configurations. As hot combustion gasses approach 6000 degrees Fahrenheit, icicles are forming on the outside of the engine nozzle.

In this image: The 3-D Printer will fabricate components and equipment on demand for manned missions to the space station and other destinations in the solar system as a part of the 3-D Printing in Zero-G Experiment.
Excerpt from the article: Suppose an astronaut needed to make a repair to a piece of equipment on the International Space Station. Today, astronauts aboard the International Space Station depend on cargo resupply missions to ferry parts and tools from Earth, sometimes waiting weeks or months for critical maintenance supplies. As we venture farther into the solar system, these cargo resupply missions will become more costly and complex, compelling NASA to consider alternate options for spacecraft supplies. Rather than stock a “spare parts” drawer, what if tools and equipment could be made right there in space?
It may seem like an unbelievable feat, but NASA's Marshall Space Flight Center awarded Made in Space a Phase III Small Business Innovation and Research Contract to develop, test and certify for flight the first mini-machine shop to perform 3-D printing in space.
The 3-D printing in Zero-G Experiment project, or 3-D Print for short, has been underway since October 2012. The resulting printer will fabricate small components and equipment on orbit and on demand.

NASA has tested a 3-D printed rocket engine turbopump with liquid methane – an ideal propellant for engines needed to power many types of spacecraft for NASA’s journey to Mars.
“This is one of the most complex rocket parts NASA has ever tested with liquid methane, a propellant that would work well for fueling Mars landers and other spacecraft,” said Mary Beth Koelbl, the manager of the Propulsions Systems Department at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “Additive manufacturing, or 3-D printing, made it possible to quickly design, build and test two turbopumps with identical designs that worked well with both liquid methane and liquid hydrogen propellant.”
A turbopump is complex because it has turbines that spin fast to drive the pump, which supplies fuel to the engine. During the full power test, the turbines generated 600 horsepower and the fuel pump, got its “heartbeat” racing at more than 36,000 revolutions per minute delivering 600 gallons of semi-cryogenic liquid methane per minute – enough to fuel an engine producing over 22,500 pounds of thrust. Three other tests were completed at lower power levels.

-----------------------------
Unified Turbine Based Combined Cycle. Current technologies and what Lockheed is trying to force on the Dept of Defense, for that low speed Mach 5 plane DOD gave them $1 billion to build and would disintegrate above Mach 5, is TBCC. 2 separate propulsion systems in the same airframe, which requires TWICE the airframe space to use.
Unified Turbine Based Combined Cycle is 1 propulsion system cutting that airframe deficit in half, and also able to operate above Mach 10 up to Mach 15 in atmosphere, and a simple nozzle modification allows for outside atmosphere rocket mode, ie orbital capable.
Additionally, Reaction Engines maximum air breather mode is Mach 4.5, above that it will explode in flight from internal pressures are too high to operate. Thus, must switch to non air breather rocket mode to operate in atmosphere in hypersonic velocities. Which as a result, makes it not feasible for anything practical. It also takes an immense amount of fuel to function.
-------------
Advanced Additive Manufacturing for Hypersonic Aircraft
Utilizing new methods of fabrication and construction, make it possible to use additive manufacturing, dramatically reducing the time and costs of producing hypersonic platforms from missiles, aircraft, and space capable craft. Instead of aircraft being produced in piece, then bolted together; small platforms can be produced as a single unit and large platforms can be produces in large section and mated without bolting. These techniques include using exotic materials and advanced assembly processes, with an end result of streamlining the production costs and time for hypersonic aircraft; reducing months of assembly to weeks. Overall, this process greatly reduced the cost for producing hypersonic platforms. Even to such an extent that a Hellfire missile costs apx $100,000 but by utilizing our technologies, replacing it with a Mach 8-10 hypersonic missile of our physics/engineering and that missile would cost roughly $75,000 each delivered.
Materials used for these manufacturing processes are not disclosed, but overall, provides a foundation for extremely high stresses and thermodynamics, ideal for hypersonic platforms. This specific methodology and materials applications is many decades ahead of all known programs. Even to the extend of normalized space flight and re-entry, without concern of thermodynamic failure.
*Note, most entities that are experimenting with additive manufacturing for hypersonic aircraft, this makes it mainstream and standardized processes, which also applies for mass production.
What would normally be measured in years and perhaps a decade to go from drawing board to test flights, is reduced to singular months and ready for production within a year maximum.
Unified Turbine Based Combined Cycle (U-TBCC)
To date, the closest that NASA and industry have achieved for turbine based aircraft to fly at hypersonic velocities is by mounting a turbine into an aircraft and sharing the inlet with a scramjet or rocket based motor. Reaction Engines Sabre is not able to achieve hypersonic velocities and can only transition into a non air breathing rocket for beyond Mach 4.5
However, utilizing Unified Turbine Based Combine Cycle also known as U-TBCC, the two separate platforms are able to share a common inlet and the dual mode ramjet/scramjet is contained within the engine itself, which allows for a much smaller airframe footprint, thus engingeers are able to then design much higher performance aerial platforms for hypersonic flight, including the ability for constructing true single stage to orbit aircraft by utilizing a modification/version that allows for transition to outside atmosphere propulsion without any other propulsion platforms within the aircraft. By transitioning and developing aircraft to use Unified Turbine Based Combined Cycle, this propulsion system opens up new options to replace that airframe deficit for increased fuel capacity and/or payload.
Enhanced Dynamic Cavitation
Dramatically Increasing the efficiency of fuel air mixture for combustion processes at hypersonic velocities within scramjet propulsion platforms. The aspects of these processes are non disclosable.
Dynamic Scramjet Ignition Processes
For optimal scramjet ignition, a process known as Self Start is sought after, but in many cases if the platform becomes out of attitude, the scramjet will ignite. We have already solved this problem which as a result, a scramjet propulsion system can ignite at lower velocities, high velocities, at optimal attitude or not optimal attitude. It doesn't matter, it will ignite anyways at the proper point for maximum thrust capabilities at hypersonic velocities.
Hydrogen vs Kerosene Fuel Sources
Kerosene is an easy fuel to work with, and most western nations developing scramjet platforms use Kerosene for that fact. However, while kerosene has better thermal properties then Hydrogen, Hydrogen is a far superior fuel source in scramjet propulsion flight, do it having a much higher efficiency capability. Because of this aspect, in conjunction with our developments, it allows for a MUCH increased fuel to air mixture, combustion, thrust; and ability for higher speeds; instead of very low hypersonic velocities in the Mach 5-6 range. Instead, Mach 8-10 range, while we have begun developing hypersonic capabilities to exceed 15 in atmosphere within less then 5 years.
Conforming High Pressure Tank Technology for CNG and H2.
As most know in hypersonics, Hydrogen is a superior fuel source, but due to the storage abilities, can only be stored in cylinders thus much less fuel supply. Not anymore, we developed conforming high pressure storage technology for use in aerospace, automotive sectors, maritime, etc; which means any overall shape required for 8,000+ PSI CNG or Hydrogen. For hypersonic platforms, this means the ability to store a much larger volume of hydrogen vs cylinders.
As an example, X-43 flown by Nasa which flew at Mach 9.97. The fuel source was Hydrogen, which is extremely more volatile and combustible then kerosene (JP-7), via a cylinder in the main body. If it had used our technology, that entire section of the airframe would had been an 8,000 PSI H2 tank, which would had yielded 5-6 times the capacity. While the X-43 flew 11 seconds under power at Mach 9.97, at 6 times the fuel capacity would had yielded apx 66 seconds of fuel under power at Mach 9.97. If it had flew slower, around Mach 6, same principles applied would had yielded apx 500 seconds of fuel supply under power (slower speeds required less energy to maintain).
Enhanced Fuel Mixture During Shock Train Interaction
Normally, fuel injection is conducted at the correct insertion point within the shock train for maximum burn/combustion. Our methodologies differ, since almost half the fuel injection is conducted PRE shock train within the isolator, so at the point of isolator injection the fuel enhances the combustion process, which then requires less fuel injection to reach the same level of thrust capabilities.
Improved Bow Shock Interaction
Smoother interaction at hypersonic velocities and mitigating heat/stresses for beyond Mach 6 thermodynamics, which extraordinarily improves Type 3, 4, and 5 shock interaction.
6,000+ Fahrenheit Thermal Resistance
To date, the maximum thermal resistance was tested at AFRL in the spring of 2018, which resulted in a 3,200F thermal resistance for a short duration. This technology, allows for normalized hypersonic thermal resistance of 3,000-3,500F sustained, and up to 6,500F resistance for short endurance, ie 90 seconds or less. 10-20 minute resistance estimate approximately 4,500F +/- 200F.
*** This technology advancement also applies to Aerospike rocket engines, in which it is common for Aerospike's to exceed 4,500-5,000F temperatures, which results in the melting of the reversed bell housing. That melting no longer ocurrs, providing for stable combustion to ocurr for the entire flight envelope
Scramjet Propulsion Side Wall Cooling
With old technologies, side wall cooling is required for hypersonic flight and scramjet propulsion systems, otherwise the isolator and combustion regions of a scramjet would melt, even using advanced ablatives and ceramics, due to their inability to cope with very high temperatures. Using technology we have developed for very high thermodynamics and high stresses, side wall cooling is no longer required, thus removing that variable from the design process and focusing on improved ignition processes and increasing net thrust values.
Lower Threshold for Hypersonic Ignition
Active and adaptive flight dynamics, resulting in the ability for scramjet ignition at a much lower velocity, ie within ramjet envelope, between Mach 2-4, and seamless transition from supersonic to hypersonic flight, ie supersonic ramjet (scramjet). This active and dynamic aspect, has a wide variety of parameters for many flight dynamics, velocities, and altitudes; which means platforms no longer need to be engineered for specific altitude ranges or preset velocities, but those parameters can then be selected during launch configuration and are able to adapt actively in flight.
Dramatically Improved Maneuvering Capabilities at Hypersonic Velocities
Hypersonic vehicles, like their less technologically advanced brethren, use large actuator and the developers hope those controls surfaces do not disintegrate in flight. In reality, it is like rolling the dice, they may or may not survive, hence another reason why the attempt to keep velocities to Mach 6 or below. We have shrunken down control actuators while almost doubling torque and response capabilities specifically for hypersonic dynamics and extreme stresses involved, which makes it possible for maximum input authority for Mach 10 and beyond.
Paradigm Shift in Control Surface Methodologies, Increasing Control Authority (Internal Mechanical Applications)
To date, most control surfaces for hypersonic missile platforms still use fins, similar to lower speed conventional missiles, and some using ducted fins. This is mostly due to lack of comprehension of hypersonic velocities in their own favor. Instead, the body itself incorporates those control surfaces, greatly enhancing the airframe strength, opening up more space for hardware and fuel capacity; while simultaneously enhancing the platforms maneuvering capabilities.
A scramjet missile can then fly like conventional missile platforms, and not straight and level at high altitudes, losing velocity on it's decent trajectory to target. Another added benefit to this aspect, is the ability to extend range greatly, so if anyone elses hypersonic missile platform were developed for 400 mile range, falling out of the sky due to lack of glide capabilities; our platforms can easily reach 600+ miles, with minimal glide deceleration.

Sandia National Laboratories researcher Bradley Jared sits in front of a new selective laser melting machine at Sandia for metal additive manufacturing as he holds two prototype housings designed through a technology called topology optimization. Sandia researchers who are exploring additive manufacturing for nuclear weapons and other national security needs say they need to understand how additive manufacturing processes affect the properties of materials that are generated.

Additive manufacturing (AM) is defined by ASTM as the 'process of joining materials to make objects, usually layer by layer, from 3D CAD data'. Additive processes include Selective Laser Melting (SLM), Laser Metal Deposition (LMD), Stereolithography, Fused Deposition Modelling (FDM) and 3D Inkjet Printing (3DP). Each technology is often distinguished by the raw materials used (including powder, wire, photosensitive liquid resins, thermoplastic filament, printing inks) or by the method of consolidation (including laser heating and melting, photo polymerisation, conduction heating, chemical reaction).
AM is seemingly opposite to subtractive manufacturing approaches that remove material to form the shape of a work piece. The traditional metal removal processes such as milling, turning, grinding, electrical discharge machining (EDM), fall into this category.
