Jeroen Sol, a fourth-year doctoral student and co-author of the review, wrote: “This report can give readers a comprehensive understanding of the choices and challenges of liquid crystal in the additive field, and encourage researchers who are already experienced in liquid crystal or additive manufacturing to take further steps. Read the full text and see how they integrate additive manufacturing or liquid crystal into their work.”
This report points out that the molecular order of liquid crystals is the main factor affecting its anisotropic quality and has a major impact on the way it responds to stimuli.Thus, in3D printingControlling the molecular arrangement during the process is crucial (especially for 4D applications), but there are several common ways to do this.
The document also continues to discuss some of the more advanced applications of 4D printed liquid crystal structures, first of all, soft robots. In soft robots, contraction strips of liquid crystal material are used as artificial muscles.These artificial muscles are usually driven by heat, light or humidity exposure and can be performed individually3D printing, Or weave them together to embed additional smart features.
Finally, the liquid crystal can also pass3D printingUsed in photonic equipment because they have a wide range of traditional uses in optical equipment. In fact, in a separate experiment conducted by the Eindhoven University team, a new type of color-changing liquid crystal ink has been developed for micro-extrusion. This ink is inspired by iridescent materials, such as the appearance of jewelry beetles, and is expected to have an impact on decorative lighting and even augmented reality optics.
