Design-to-Build Link Improves Strength and Precision of 3D-Printed Parts Design-to-Build Link Improves Strength and Precision of 3D-Printed Parts
HONG KONG, Jan. 2, 2025 — Stereolithography (STL) files, used to convert digital designs into printable layers, play a central role in the 3D printing of metallic lattice structures. Although STL files have been used for decades, it is difficult to achieve high resolution, precision, and structural integrity with STL. An international research team devised a remedy for the bulky file sizes and imprecise geometric estimates that come with STL. Researchers from the Chinese University of Hong Kong, the University of
