Skyrora Cut Rocket Engine Mass 44% With Titanium Coating: What Six Hot-Fire Tests Mean for Your Parts

Skyrora titanium hot-fire cover with 44% Lighter title

Key takeaways

  • Skyrora finished a hot-fire campaign on a 3.5 kN low Earth orbit engine at its Midlothian facility, as reported by TCT Magazine and 3D Printing Industry.
  • The engine used a titanium-coated component from the EU-funded MADE-3D (Horizon Europe) program, deposited on Skyrora's in-house Skyprint 2 hybrid directed energy deposition (DED) system.
  • Skyrora says swapping a nickel-based alloy for titanium cut component mass by about 44%.
  • Trade coverage says the company ran six live firings and reported no damage to the modified component after inspection.
  • The lesson for working shops is not "buy a rocket printer." It is prove the process under real loads, pick materials for heat and weight, and keep a path to replace parts when drawings disappear.

UK launch company Skyrora just closed out a real-world test that additive manufacturing people should actually care about. Not another concept render. A 3.5 kN low Earth orbit engine, fired live, with a titanium-coated part built through a multi-material research program.

According to TCT Magazine (Sam Davies, published September 10, 2026) and 3D Printing Industry, the campaign ran at Skyrora's Midlothian test site and wraps the company's technical role in MADE-3D, a Horizon Europe consortium focused on multi-material additive manufacturing for space. The modified engine carried a titanium-coated component deposited on Skyrora's Skyprint 2 hybrid DED printer. Skyrora says that titanium path cut mass by about 44% versus a nickel-based alloy, and that six firings left the modified component undamaged under inspection.

That is the whole story in one sentence: lighter metal, deposited in layers, then proven where it counts, in the fire.

What did Skyrora actually prove in the hot-fire campaign?

They proved a multi-material additive part can survive live engine firings, not just a lab coupon test.

Jordan McCormick, Design and Test Engineer at Skyrora, put the hard part in plain language in the TCT write-up: the biggest challenge in advanced manufacturing is moving promising tech out of the lab and into real operating environments. The company says the titanium coating was chosen for the thermal environment of rocket operation, and that X-ray style inspections before and after the six firings (as reported by 3D Printing Industry) showed no damage to the modified component.

MADE-3D's pitch, per the same coverage, is that one manufacturing process can put different materials in different regions of a single part, so you can tune strength, weight, and thermal behavior without bolting five sub-assemblies together. For a launch vehicle, that can mean fewer joints and less mass. For everyone else, it is a reminder that "can we print it" is the wrong first question. "Can we prove it under the load it will see" is the right one.

My bracket sees heat and weight matters. Do I need metal DED for that?

No. Most heat-and-weight jobs on the shop floor still start with the right polymer and a verified CAD model, not a hybrid DED cell.

Rocket engines live at temperatures and pressures that demand metal. Your fixture, duct adapter, high-temp manifold, or enclosure usually does not. When the duty cycle is heat, chemicals, or continuous load, engineering polymers such as PEEK and ULTEM already do serious work today. That is why we run a PEEK and ULTEM high-temp parts path for buyers who need performance without waiting on exotic metal research.

Skyrora's 44% mass claim (their number, as reported) is still useful as a design prompt. Ask where weight is costing you, where heat is killing a plastic that was never meant for that zone, and whether a material swap beats a geometry redesign. Sometimes the answer is a thinner wall in a stronger polymer. Sometimes it is a metal insert. Rarely is the first answer "buy a rocket printer."

I need a replacement part and the OEM drawings are gone. What should I do first?

Scan the mating hardware, rebuild design intent in CAD, then pick the process that matches duty cycle and quantity.

Aerospace stories get the headlines, but the daily failure mode for manufacturers is quieter: a discontinued bracket, a latch the OEM will only sell as a full assembly, a fixture that cracked after a line change. That is a scan-to-CAD problem before it is a print problem. Capture the geometry, reconstruct the interfaces, grade what you know versus what you inferred, then decide polymer, metal, or hybrid.

If that is the hole you are in, our 3D scanning and reverse engineering service exists for exactly that workflow. No walk-in storefront required. You ship the part or we work from your photos and measurements, then you get a manufacturable model instead of a guess.

What this means if you actually need parts this month

Skyrora's campaign is a clean proof loop: design for multi-material performance, deposit the critical zone, fire it, inspect it, close the MADE-3D chapter. Your version of that loop is smaller and more practical.

  1. Define the load, heat, and chemical environment in writing.
  2. Get a trusted CAD model (OEM file, or scan and rebuild).
  3. Choose material for duty cycle, not for hype.
  4. Fit-check a prototype when the interface is unforgiving.
  5. Move to a short production run without a minimum-order trap.

When you want that last step handled in the USA with no minimums, our Build and Ship workflow takes a file or a concept through to finished parts. We are not claiming we hot-fire rocket engines. We are saying the same discipline (prove the process, then ship) is how custom polymer and engineered parts should get made for makers and plant teams.

Frequently asked questions

Did Skyrora really cut engine component mass by about 44%?
According to Skyrora, as reported by TCT Magazine and 3D Printing Industry, replacing a nickel-based alloy path with a titanium alloy coating deposited on Skyprint 2 enabled about a 44% weight reduction on the modified component. Treat that as a company-reported figure from trade coverage, not an independent lab audit published in the articles we reviewed.

How many hot-fire tests did the titanium-coated part see?
Coverage says Skyrora ran six live firings and reported no damage to the modified component after inspection. 3D Printing Industry specifically mentions X-ray inspections before and after the firings.

What is MADE-3D?
MADE-3D is described as an EU-funded Horizon Europe consortium working on multi-material additive manufacturing for space applications. Skyrora's hot-fire campaign closes its technical contribution to that program, per TCT.
