Ann: 3DA:Amaero Raises $9 million in Strongly Supported Placement, page-13

RE: Agreement with between Amaero (3DA) and Rio Tinto to collaborate on alloy for 3D printing

These parts of the anouncement stood out for me:
"Once commercialised, Amaero HOT Al will also be used in conjunction with Boron
Nitride Nano Tubes under the Strategic Alloys JV."

Forecast volume: Over the term of the agreement, Rio Tinto will supply a forecast quantity of 60-75
tonnes of AlMnSc billet products at an estimated total value of >$9 million

That seems like a large volume to commit to so the volumes expected must be substantial.
Therefore PPK via Amaero is advancing the proccess of commecialization of PPK in the aerospace, defence and sports sectors.

It's only a matter of time before BNNT becomes a household name and is widely used, the question is how long will it take and at what point does the market take seriious interest?
