Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 August 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Abstract

Laser powder bed fusion (LPBF) is a metal additive manufacturing process that uses a focused high-energy laser to selectively melt metal powders layer by layer, enabling the production of geometrically complex parts for aerospace, biomedical, and other industries. However, localized laser heating creates a highly dynamic interaction region involving powder, molten metal, vapor jet, and gas flow. These elements…
