Imaging Method Traces 3D-Printed Objects Back to Their Source

Facebook Twitter LinkedIn Email
BUFFALO, N.Y., Oct. 19, 2018 — A University at Buffalo research team has developed a method for tracing 3D-printed objects back to the machines that printed them. PrinTracker is a 3D-printer identification system that can precisely trace the printed physical object to its source 3D printer based on the object’s “fingerprint.” Each layer of a 3D-printed object contains tiny wrinkles — usually measured in submillimeters — called in-fill patterns. These patterns are supposed to be uniform. However, the printer’s model type, filament, nozzle size, and other factors can cause slight...Read full article

    stereolithography
    A method of creating real three-dimensional models by using lasers driven by CAD software. In contrast to the normal practice of removing material, this process polymerizes a liquid to quickly produce shapes that are untouched by human hands or cutting tools. Also known as three-dimensional imaging and three-dimensional modeling.
