Multimaterial Microrobots for pH Sensing Fabricated Using Sequential 3D and 4D Printing with Automated Alignment

Advanced Materials Technologies, EarlyView.
This work proposes the use of multimaterial microrobots for pH sensing. The microrobots consist of a hard polymer backbone and 4D printed sensing elements made of a pH‐responsive hydrogel. The swelling response, reusability, and high mobility of the microrobots make them promising tools for pH sensing at the micro scale.

Printability Metrics in Direct Ink Writing: Critical Review of the Literature and Novel Perspective Based on Dimensional Analysis

Advanced Materials Technologies, EarlyView.
The impossibility of defining universal printability criteria for Direct Ink Writing (DIW) requires “unpacking” the process into printing subfunctions. Each of these is rationalized by identifying dimensionless groups, allowing effective comparison between the various material‐ and process‐related parameters for printability purposes.

A Thermally Expandable Resin for the Volumetric Additive Manufacturing of Shape‐Memory Functional Foams

Advanced Materials Technologies, EarlyView.
Volumetric additive manufacturing allows to print parts extremely fast, but is so far is limited by the build volume of the printers. The foaming materials presented here allow to expand printed parts up to 500% reaching densities of 0.16 g cm−3 as well as providing shape memory properties enabling the creation of lightweight, functional parts ...
