a The sintering rate constant \(\varkappa\) and b \(- \ln (1 - \varrho )\) as a function of the specific energy input Ψ. Linear fittings are illustrated by the red lines; c map of densification factor \(\varrho\) along with different laser power and scan speed, where the dash-dotted lines denote different specific energy input Ψ
