01 / Current demonstrator
3 kN engine
3 kN demonstrator with an additively manufactured chamber and multi-port injector.
PBF-LB manufacturingResearch & development / Avaris
Built to
scale.
A family of additively manufactured rocket engines, developed across four thrust classes for the next generation of propulsion systems.
Avaris propulsion programme
One architecture.
Four thrust classes.
Avaris develops multi-metal engines across 1.5, 3, 5, and 28 kN thrust classes. The 1.5–5 kN designs use laser powder bed fusion to integrate chambers, injectors, and cooling channels.
Engine family
From laboratory demonstrator
to flight-scale hardware.

Future scale
28 kN engine
Future engine class reserved for a larger propulsion demonstrator and flight-system applications.
Development targetManufacturing strategy
Complexity where
it matters.
Next steps: material selection, post-processing, hot-fire testing, and repeatable production.
