By putting 3D printers behind the front line it hopes to be able to produce spares more cheaply and quickly than it can get them from manufacturers.
The army embarked on the project to produce its own printer as commercial devices were too expensive. Early versions of the printer cost $695 (£436) compared to $3,000 (£1,880) for a commercial model.
The 3D printer has been developed by the Future Warfare centre at the US Army's Space and Missile Defense Command (SMDC) in Alabama.
3D printers are gadgets that form objects by melting and shaping plastic into a design dictated by a data file. They are becoming increasingly common and many engineering and research firms use them for rapid prototyping.
"The ability to replicate parts quickly and cheaply is a huge benefit to the warfighter," said D Shannon Berry, an operations research analyst at the Future Warfare office, in a statement. Eventually, it is hoped the printer will find a larger role with US forces deployed overseas.
