Problems solved by technology

However, in view of its complex structure, except that two-dimensional metamaterials can be directly formed by simple methods such as photolithography, the preparation process of three-dimensional metamaterials is extremely cumbersome, and the unit structure needs to be prepared first and built. Method limits the development and application of metamaterials

Embodiment 1

[0057] A 40*40cm metal box is used, and the size of the bottom plate is 25*25cm.

[0058] The substrate deposition system uses the fusion deposition method, adopts a single extrusion needle with a heating jacket, the diameter is 0.5 mm, the deposition temperature is 180 °C, and the deposition material is ABS resin. A single inkjet nozzle with a diameter of 0.3 mm is used, which is arranged in parallel with the extrusion needle, and the two move independently. Silver nanoparticles (average size 100 nm) ink was used. Both the extrusion needle and the inkjet nozzle are driven by two motors, and each moves in the XY plane, while the bottom plate is driven by a single motor, and moves in the Z direction. The temperature of the cabinet is controlled at 50°C and the relative humidity is less than 5%.

Abstract

The invention relates to 3D printing equipment for metamaterial preparation. The 3D printing equipment comprises a substrate deposition system, a loop deposition system and a pivot control system, wherein the pivot control system controls the substrate deposition system and the loop deposition system; the substrate deposition system is controlled by the pivot control system to construct a substrate of a metamaterial periodical structure; the substrate provides an adhesion site to an electric conducting loop structure; and the loop deposition system is controlled by the pivot control system todeposit electric conducting substances on the substrate, constructed by the substrate deposition system, through an ink jet gun head to form an electromagnetic wave response structure. The 3D printingequipment uses the substrate deposition system and the loop deposition structure for realizing synchronous printing of a substrate material and an electric conducting material to construct a metamaterial with a periodical structure or a similarly periodical structure.

Description

technical field [0001] The invention relates to a supermaterial preparation technology, in particular to a 3D printing device for supermaterial preparation. Background technique [0002] Metamaterials, also known as heterogeneous media, have extraordinary physical properties that natural materials do not possess. Such materials are generally composed of a series of regular arrangements of structural units, which have a periodic structure similar to atoms in crystals, and each structural unit can be understood as an LC loop. As a result, metamaterials resonate with electromagnetic waves of a specific frequency, resulting in unique electromagnetic properties, such as properties such as an apparent negative permittivity (permeability). These characteristics determine that metamaterials have very attractive prospects in imaging, stealth, communication and other fields. [0003] Each structural unit of metamaterials can be regarded as an LC loop, so a specific conductive struct...
