3D Printed Titanium Replaces Aluminum for Unmanned Aircraft Wing Splice | The Cool Parts Show Ep.72

Aircraft makers applying 3D printing processes to manufacture plane components often begin with less critical parts first, then proceed to more vital parts as confidence builds. But with General Atomics’ introduction of directed energy deposition (DED) to part production, the company began with a part that could not be more critical to flight. DED via the Rapid Plasma Deposition process from Norsk Titanium will be used to 3D print the wing splice for an unmanned aerial system following requirements similar to those of the company’s existing SkyGuardian aircraft. That is, this process will make the part that affixes the wings to a remotely piloted plane. Producing the part this way makes it practical to apply titanium to a component previously machined from aluminum, allowing a more compact design. The Cool Parts Show visited Norsk Titanium in Plattsburgh, New York, where the General Atomics wing splice will be made.

FOR ALL ACCESS MEMBERS: In the episode, Steve Fournier of General Atomics mentions how AM potentially makes titanium more economical than aluminum. That sounds counterintuitive, because aluminum’s raw material cost is less. Fournier says total cost of manufacturing is what is important, and he lays out the argument in detail in an exclusive Extra just for subscribers.
