Study of defects and dimensional accuracy to determine manufacturability thresholds for laser powder bed fusion of Ti‑6Al‑4V lattices

This publication relates to work that QCML performed to better understand the dimensional and geometric limitations when 3D printing Ti-6Al-4V lattice structures using powder bed fusion technology.  The knowledge acquired provides a framework for design limitations that need to be considered when fabricating lattice structures through powder bed fusion additive manufacturing.  The results of this study support parallel research in the development of 3D printed lattice structures for ballistic protection applications.  This work was supported by the funding received from Army
Research Lab Cooperative Agreement W911NF-18–2-0067.
