While increasing research focus has been given to developing the capability to modulate the properties of 3D printed devices, combining the possibilities offered by stimuli-responsive and adaptive polymers with advanced 3D printing technologies holds great promise in meeting the ever‐increasing demand of complex device platforms.

Recent focus points are devoted to the design of printable polymeric materials and (nano)composites with desired properties and boosted functionalities including but not limited to:

  • 3D-printed and 4D-printed materials,
  • Shape-memory materials,
  • Self-healing materials,
  • Photonic materials,
  • Electrically and thermally conductive materials,
  • Piezoelectric and piezoionic materials,
  • Energy-harvesting materials,
  • Flame-retardant materials,
  • Shape-morphing actuators,
  • Sensing devices,
  • Biomedical devices.

Tough and Three-Dimensional-Printable Poly(2-methoxyethylacrylate)-Silica COmposite Elastomer with Antiplatelet Adhesion Property

Fumio Asai, Takahiro Seki, Ayae Sugawara-Narutaki, Kazuhide Sato, Jérémy Odent, Olivier Coulembier, Jean-Marie Raquez, and Yukikazu Takeoka Poly(2-methoxyethyl acrylate) (PMEA) has attracted attention as a biocompatible polymer that is used as an antithrombotic coating agent for medical devices, such as during artificial heart and lung fabrication. However, PMEA is a viscous liquid polymer with low Tg, and its physical strength is poor even if a cross-linker is used, so it is difficult to make tough and freestanding objects from it. Here, we design and fabricate a biocompatible elastomer made of tough, self-supporting PMEA−silica composites. The toughness of the composite elastomer increases

Highly Elastic, Transparent, and Conductive 3D-Printed Ionic Composite Hydrogel

Jérémy Odent, Thomas J. Wallin, Wenyang Pan, Kevin Kruemplestaedter, Robert F. Shepherd, and Emmanuel P. Giannelis Despite extensive progress to engineer hydrogels for a broad range of technologies, practical applications have remained elusive due to their (until recently) poor mechanical properties and lack of fabrication approaches, which constrain active structures to simple geometries. This study demonstrates a family of ionic composite hydrogels with excellent mechanical properties that can be rapidly 3D-printed at high resolution using commercial stereolithography technology. The new material design leverages the dynamic and reversible nature of ionic interactions present in the system with the reinforcement ability of

Hierarchical chemomechanical encoding of multiresponsive hydrogel actuators via 3D printing

Jérémy Odent, Sophie Vanderstappen, Antoniya Toncheva, Enzo Pichon, Thomas J. Wallin, Kaiyang Wang, Robert F. Shepherd, Philippe Dubois and Jean-Marie Raquez Inspired by nature, we herein demonstrate a family of multi-responsive hydrogel-based actuators that are encoded with anisotropic swelling behavior to provide rapid and controllable motion. Fabrication of the proposed anisotropy-encoded hydrogel actuators relies on the high resolution stereolithography 3D printing of functionally graded structures made of discrete layers having different volume expansion properties. Three separate synthetic strategies based on (i) asymmetrical distribution of a layer's surface area to volume ratio via mechanical design, (ii) crosslinking density via UV photo-exposure, or
