RAMUS: Printable, Mechanically‐Tunable and Biodegradable Cellulose‐Mediated Composites

Advanced Materials Interfaces, Volume 13, Issue 1, 7 January 2026.
Ramus, a Latin term meaning “branch,” develops large‐scale, ambient conditions additively manufactured, and biodegradable cellulose‐based biomaterial composites able to mediate their structural capacity from micro to macroscale. Abstract Ramus develops large‐scale, ambient conditions additively manufactured, and biodegradable cellulose‐based ...

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel

Advanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Detecting Sabotage Attacks in Additive Manufacturing Using Actuator Power Signatures

IEEE Access, 2019
Additive manufacturing (AM), a.k.a. 3D printing is increasingly used to manufacture functional parts of safety-critical systems. The AM's dependence on computerization raises the concern that the AM process can be tampered with, and a part's mechanical ...

Jigsaw Pattern Infills Inspired by Toughening Mechanisms of Diabolical Ironclad Beetle for 3D Printing Technologies

Advanced Materials Technologies, Volume 10, Issue 24, December 17, 2025.
A biomimetic Jigsaw pattern infill for 3D printer has been developed. Its mechanical features with continuous carbon fiber reinforcement (CCFR) are investigated through the Design of Experiments. The Jigsaw infill minimizes mechanical strength losses caused by variability in infill density, flow rate, or carbon fiber string amount, outperforming ...

Multiresolution Layered Manufacturing [PDF]

, 2018
PURPOSE: Two-photon polymerization (TPP) has become one of the most popular techniques for stereolithography at very high resolutions. When printing relatively large structures at high resolutions, one of the main limiting factors is the printing time ...
