The SLS AM consumable...
As of June 2019, MakerSpace USNA does not have any active powder based 3D printers. This will change by late 2019 as we integrate the Formlabs Fuse1 nylon based 3D printer.
Additionally although not directly associated with the MakerSpace, USNA does have a Concept Laser M100R (https://www.concept-laser.de/en/products/machines.html) 3D metal printer which is currently capable of printing stainless steel parts.

Be careful not all powders are created equal!
Particle size and purity have large effects on the quality of 3D printed parts.
