Abstract

The National Institute of Standards and Technology developed a facility titled the Additive Manufacturing Metrology Testbed to advance the research in laser powder bed fusion (LPBF) processes. The testbed adopted an open control architecture which allows full access to all key process parameters. Although LPBF control is a very important topic, very little literature can be found on how this is implemented. This paper reviews the testbed control software design and implementation. Scan path planning, galvo motion control, and laser power control are detailed with select highlights. Comparison with commercial machine control software is made, and recent experiments utilizing the advanced features of the testbed control software are also discussed.
