Printability Analysis in Additive Manufacturing [PDF]

Proceedings of CAD'17, 2017
In recent years Additive Manufacturing (AM) has advanced from design and fitting validation to biomedical, rapid tooling, tissue engineering, the arts and even food manufacturing. The corresponding scale reduction did not coincide with improving two of the most important process characteristics, namely print accuracy and build time.

Biometric Backdoors: A Poisoning Attack Against Unsupervised Template Updating

, 2020
In this work, we investigate the concept of biometric backdoors: a template poisoning attack on biometric systems that allows adversaries to stealthily and effortlessly impersonate users in the long-term by exploiting the template update procedure.

4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing

Advanced Functional Materials, EarlyView.
A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.
