About this Research Topic
The controllable change in shapes, properties, or functionalities of 4D printed components needs to be stimulated by the external environments such as heating, electricity, magnetism, light, pH, solvent, and biological signals. In this research topic, the problems to be tackled are that heating dominates the external stimuli form and most studies only achieve the change in shapes due to the inertial thinking of applying smart materials in additive manufacturing. Therefore, the purpose of the subsequent research is to develop new smart materials, novel 4D printing process, and new research ideas for 4D printing with variable properties and functionalities. In addition, the characterization method of controllable change in shapes, properties, and functionalities of intelligent components and its special simulation technology need to be studied as a key point because they are rarely involved at present.
This Research Topic aims to publish cutting-edge original research papers studying the latest advances in the new smart materials & structures, 4D printing process and finite element model, and reviews that describe the current state of the art. Manuscripts about performance-changed and functionality-changed 4D printing are especially welcome. Potential topics include but are not limited to the following:
• New and advanced smart materials development for 4D printing
• Design theory of smart materials and structures for 4D printing
• Novel 4D printing processes
• Multi-material 4D printing
• Characterization techniques for the controllable change in shapes, properties, or functionalities of 4D printed components
• 4D printing process modeling and simulation for 4D printed components
• Interrelationship model among material, process, property, and functionality of 4D printing
