Additive manufacturing, or 3D printing attracts growing attention as a promising method for creating functionally graded materials. Fused deposition modeling (FDM) is widely available, but due to its simple process, spatial gradation of diverse properties using FDM challenging. Here, we present printed digital material filament that structured towards functional gradients, utilizing only readily available printer and filaments. The DM consists multiple base materials combined with specific...
Origami provides a unique tool for the design of robotic frames owing to its simple shaping principle by "folding." However, achieving fast and reversible activeness highly reconfigurable structure remains challenging limitations accessible actuators. In particular, it is difficult find an actuator that can realize simultaneously large, rapid, reversible, stable movement while leading favorable form factor origami. To overcome this, in this article, we propose 3-D shape-shifting system...
Abstract 4D printing can address time‐evolving structural functions that are unattainable by conventional 3D printing. Despite the advance in materials and techniques, however, of continuity shape representation generally characterizes matters is still challenging, because existing methodologies mostly rely on a few discrete levels strain their spatial distributions. Here, strategy memory polymers (SMPs) program continuous shape‐recovery proposed. It found irrecoverable state SMP...
