The invention provides a complex-frequency electrohydrodynamics printing device and a printing method of the complex-frequency electrohydrodynamics printing device. The complex-frequency electrohydrodynamics printing device and the printing method of the complex-frequency electrohydrodynamics printing device mainly solve the problems that in an existing processing method of existing polymer metal nanoparticle composites, operation is complicated, and parameters are difficult to control and the problem that in an electrohydrodynamics processing machine, voltage application is difficult to control. The complex-frequency electrohydrodynamics printing device is characterized in that a direct-current electric field, a high-frequency alternating-current electric field and a medium-frequency alternating-current electric field jointly form a complex-frequency voltage, the complex-frequency voltage is v, and v=v0+v1(sin omega<1>t)+v2(sin omega<2>t+phi). The complex-frequency electrohydrodynamics printing device and the printing method of the complex-frequency electrohydrodynamics printing device have the advantages that the complex-frequency voltage avoids the situation that in the electrohydrodynamics printing process, due to application of an ultrahigh voltage, the polymer nanoparticle composites with the insulating performance lowered generate electric breakdown, and it can be guaranteed that under the condition of the ultra-high voltage, the increase of the surface charge density of a printing liquid drop cannot cause the corona electric discharging phenomenon.
Description
technical field [0001] The invention relates to the technical field of 3D printing, in particular to a multi-frequency electrohydrodynamic printing device and a printing method thereof. Background technique [0002] The 3D printing of polymer-metal nanoparticle composites is one of the new research directions and key development areas in the current additive manufacturing research. Polymer-metal nanoparticle composites change the physical and chemical properties of the polymer due to the addition of metals and produce new features different from the polymer matrix and metal nanoparticles themselves. 3D printing can produce special micro-nano structures and have a variety of new properties. Functions (magnetic, dielectric, piezoelectric, photoelectric and other super functions), its application fields are very wide, from metamaterials, quantum tunneling, flexible sensors to various nano-functional devices and other fields have application prospects. [0003] The main methods...
