One of the main challenges facing selective laser melting processes is finding suitable
process parameters to achieve maximum density (pore-free) parts. In this letter, two newly
discovered dimensionless numbers are presented that correlate process parameters to a
part's density allowing for an initial estimation of suitable process parameters without the
need for extensive modeling or experimentation. The prediction is achieved by utilizing the
Buckingham-Π theorem and the implementation of Pawlowski's matrix transformation …
