  • Shape-shifting structures are important building blocks in the design of reconfigurable materials and devices with advanced functionalities. Here, versatile metamaterials with 3D-to-3D shape-shifting behavior upon thermal activation are fabricated by adapting a 3D printer to print on curved surfaces.

  • It remains unclear how cells respond to complex extracellular geometries at the mesoscale. Here, the authors study the organization of bone cells in landscapes with varying curvatures, observing a preference for local concavities, multicellular bridging, and collective stress fiber orientation.

  • Temporomandibular joint prostheses have limitations in their translational movements that affect functionality and longevity. Here, a 3D-printed functionally graded artificial cartilage attached to the temporomandibular joint implant improves the mandibular kinematics and movement range.

  • 4D printing techniques enable the realization of smart materials whose shape or properties can change with time. Here, utilizing the anisotropic deformation of a combination of polymers and the distribution of microdefects formed during the 3D printing process, the authors realize a variety of shape-changing curved structures that can be used in drug delivery systems.

  • The ability of a structure to reliably change its shape is key to the function of various organisms in nature, as well as for applications such as implants and robotics. Here, a methodology is shown to predict shape-morphing in kinematic structures, based on geometrical multibody design of connecting elements and joints.

  • The 3D stiffness of a self-folded metamaterial structure is limited by the low stiffness required by the folding process. Here, the stiffness limits of self-folding bilayers are theoretically established by a nonlinear model and experimentally validated on polymer-metal composites, providing the optimal combinations of geometrical and mechanical properties of folded constructs.

  • Multi-material 3D printing techniques are now enabling the rational design of metamaterials with both complex geometries and multiple materials compositions. Here, deep-learning methods are used to identify, among planar network structures, the rare designs that yield very unusual and desirable combinations of materials properties.
