Additive Manufacturing of Lignocellulosic Aerogels from Minimally Processed Waste Streams

This study showcases the use of lignocellulosic pastes for the additive manufacturing of lightweight and load-bearing porous materials. The pastes are obtained via a milder approach compared to the isolation of conventional cellulose nanomaterials and cont ...

Controlling the Microstructure and Composition of 3D Printed Soft Load-Bearing Hydrogels

Matteo Hirsch

Hydrogels are among the first materials expressly designed for their use in biomedicine. However, state-of-the-art applications of hydrogels are severely limited because they are typically either too soft or too brittle such that they cannot bear significa ...

4D printing of Metal-Reinforced double network granular hydrogels

Esther Amstad, Matteo Hirsch, Josephine Anna Eleanor Hughes, Qinghua Guan, Livia D'Onofrio

Recent developments in soft actuation demand for resilient, responsive materials with locally varying compositions that are sufficiently stiff to exhibit significant actuation forces. Hydrogels are inherently responsive to certain stimuli. Yet, they typica ...

Porous 3D Printable Hydrogels

Esther Amstad, Matteo Hirsch

Hydrogels are interconnected, polymeric networks filled with water. Their inherent responsiveness to different stimuli, including the presence of salt, solvents, or, depending on their composition, changes in pH or temperature, renders them attractive for ...

Additive Manufacturing of Porous Biominerals

Esther Amstad, Matteo Hirsch, Gaia De Angelis, Ran Zhao, Tianyu Yuan

Nature fabricates hard functional materials from soft organic scaffolds that are mineralized. To enable an energy-efficient locomotion of these creatures while maintaining their structural stability, nature often renders parts of these minerals porous. Unf ...

3D printing of living structural biocomposites

Esther Amstad, Matteo Hirsch, Lorenzo Lucherini, Ran Zhao

Nature fabricates organic/inorganic composites under benign conditions, yet, in many cases, their mechanical properties exceed those of the individual building components it is made from. The secret behind the evolutionary pivot is the unique ability of na ...

Reinforcing hydrogels with in situ formed amorphous CaCO3

Michael David Kessler, Huachuan Du, Esther Amstad, Matteo Hirsch, Ran Zhao, Tianyu Yuan

Hydrogels are often employed for tissue engineering and moistening applications. However, they are rarely used for load-bearing purposes because of their limited stiffness and the stiffness-toughness compromise inherent to them. By contrast, nature uses hy ...

Recycling of Load-Bearing 3D Printable Double Network Granular Hydrogels

Alvaro Lino Boris Charlet, Esther Amstad, Matteo Hirsch, Sanjay Phileas Schreiber

Sustainable materials, such as recyclable polymers, become increasingly important as they are often environmentally friendlier than their one-time-use counterparts. In parallel, the trend toward more customized products demands for fast prototyping methods ...

Load-bearing hydrogels ionically reinforced through competitive ligand exchanges

Esther Amstad, Mathias Steinacher, Matteo Hirsch, Ran Zhao

Fast advances in soft robotics and tissue engineering demand for new soft materials whose mechanical properties can be interchangeably and locally varied, thereby enabling, for example, the design of soft joints within an integral material. Inspired by nat ...

Controlling the calcium carbonate microstructure of engineered living building materials

Lyesse Laloui, Esther Amstad, Dimitrios Terzis, Alexandra Clarà Saracho, Hannes Markus Peter, Matteo Hirsch, Lorenzo Lucherini

The fabrication of responsive soft materials that enable the controlled release of microbial induced calcium carbonate (CaCO3) precipitation (MICP) would be highly desirable for the creation of living materials that can be used, for example, as self-healin ...
