Intelligent　additive　manufacturing　is　the　direction　of　development,　and　changing　parameters　during　the　manufacturing　process　is　an　effective　measure　to　adjust　the　quality　of　the　part.　The　purpose　of　this　paper　is　to　investigate　the　stability　of　single-track　and　multilayer　fabricated　Ti-6Al-4　V　designed　and　fabricated　by　laser　powder　bed　fusion　with　high　degrees　of　freedom.　The　effects　of　single-track,　relative　density,　surface　quality,　and　microstructure　and　mechanical　properties　were　investigated　by　designing　a　process　strategy　based　on　the　interval　powder　layer　thickness　and　regulating　the　process　parameters.　The　survey　shows　that　the　point　distance　of　less　than　35　mu　m,　the　exposure　time　of　longer　than　120　mu　s,　and　the　hatch　spacing　of　greater　than　70　mu　m　can　ensure　the　relative　density　of　specimens　with　high　layer　thickness.　The　microstructure　consists　mainly　of　acicular　martensite　a＇　filled　in　columnar　ss　grains,　and　acicular　martensite　a＇　grains　are　relatively　sparse.　The　tensile　strength,　yield　strength,　and　elongation　of　the　specimens　were　1109　MPa,　1053　MPa,　and　5.6%,　respectively.　The　fracture　is　a　combination　of　ductile　fracture　and　brittle　fracture.　The　building　rate　was　9　mm(3)/　s,　which　is　higher　than　the　results　obtained　in　previous　studies.　The　survey　can　provide　theoretical　support　for　researchers　and　data　support　for　engineers.
