The Airbus A350 XWB has more 3D-printed elements than any
other commercial passenger jet. The roughly 1,000 parts were
created in partnership with Stratasys, the additive
manufacturing company.

Stratasys reportedly used an ULTEM 9085 resin, which is
certified to an Airbus material specification, to fabricate
each part on an FDM 3D printer. The process melted the resin
and extruded it layer by layer until entire parts were
fabricated. This method produces parts that are lighter in
weight and strong, as well as being flame, smoke and
toxicity compliant.

In aerospace, AM is producing turbine engine compressor blades, and
some driven turbine blades, from a chrome-cobalt superalloy. Other
parts are being made from maraging steel, precipitation-hardening
stainless (17-4 PH and others), and several grades of aluminum and
titanium. These are 100% dense; they're not sintered parts.

If you want a quick rundown of the metals they can print, the article
I linked to earlier gives the highlights. It just applies to the
laser-melting process. There are some other metals that are included
in the electron-beam-melting and other AM processes:

The difficult part is applying AM to fast-quenching, heat-treatable
steels and other heat-treatable metals. That's where the research is
being applied now.
