The components where additive wins.

Thirty-nine part families across Space, Missiles & Defence, Aero Engine, Airframe and UAV, Medical and Industry, each tied to the approval that releases it. We screened every one for the geometry, alloy, recurrence and qualification path where metal additive manufacturing beats every alternative.

Every image is a concept render of a part family on its build plate. Medical families are made under ISO 13485 for orthopaedic OEMs abroad. Every part will be qualified to its programme’s acceptance criteria before it ships.

Don’t see your part? That’s the conversation.

We screen every candidate part for the geometry, alloy and economics where additive wins, and if it does not win on yours, we will say so.
