Spatial Stiffness Programming in Single‐Filament Material Extrusion Through Data‐Driven Thermal Foaming

Advanced Materials Technologies, EarlyView.
Single‐filament material extrusion enables spatial stiffness programming through locally controlled thermal foaming of TPU. A data‐driven G‐code framework tunes porosity from 15.7% to 40.7% and hardness from 90 to 63 Shore A within and across layers. Monolithic hands and soft actuators consequently achieve distinct programmed motions without material ...

Manufacturability and limitations in incremental sheet forming

Proceedings of the Estonian Academy of Sciences. Engineering, 2007
In the actual incremental sheet forming process two kinds of risks can be outlined: material failure and tool failure. From the point of view of safe manufacturing, both risks should be minimized. The aim of the current study is to predict material and tool failure.

Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

Advanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.

Investigation on the material flow and deformation behavior during ultrasonic-assisted incremental forming of straight grooves

Journal of Materials Research and Technology, 2020
The introduction of ultrasonic vibration is proved to be beneficial for the reduced force and improved formability for sheet forming processes. However, the vibration-induced material behavior is still not satisfactorily explained.

Processing‐Driven Engineering of Transparent Conductive In‐Zn‐O Thin Films: A Comparative Study of Spin‐Coating, Inkjet Printing, and Screen Printing

Advanced Materials Technologies, EarlyView.
Transparent, electrically conductive In–Zn–O thin films are solution‐processed by spin coating, inkjet printing, and, as demonstrated here for the first time, screen printing. The chosen deposition technique determines the solution composition, which in turn governs the resulting microstructure and optoelectronic performance.

Properties of Components with Incrementally Formed Gears

Metals, 2019
The process class of sheet-bulk metal forming (SBMF) involves several advantages for the manufacture of functional components. Its incremental variant (iSBMF) enables a very flexible dimensioning of components. To treat the unfavorable manufacturing time

Piezoresistivity Enhancement by Graphite Flake Alignment in Thin Composite Films for Dielectric Elastomer Switches

Advanced Robotics Research, EarlyView.
This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.
