The invention discloses a magnetic active composite material structure printing device which comprises a motor driving power supply, a high-voltage direct-current power supply, an excitation power supply, a motor, a rotating needle, a material storage barrel, a collector and a horizontal movement platform; one end of the rotating needle is coaxially connected with an output shaft of the motor, and the other end of the rotating needle is arranged in the material storage barrel; a nozzle allowing liquid in the barrel to flow out is arranged at the end, away from the rotating needle, of the material storage barrel; the collector is arranged below the nozzle and fixed to the horizontal movement platform; an excitation coil wound around the material storage barrel is arranged on the periphery of the material storage barrel, and the positive output end and the negative output end of the high-voltage direct-current power supply are connected to the material storage barrel and the collector through conductors respectively; and the motor driving power supply is electrically connected with the motor, and the excitation power supply is electrically connected with the excitation coil. The magnetic active composite material structure printing device has the advantages of overcoming the defects of non-uniform and discontinuous dispersion, advanced curing and the like of the magnetic composite material, overcoming the defects of insufficient, non-uniform and discontinuous directional chaining, and changing the direction of the magnetic pole in real time.

Description

technical field [0001] The invention relates to a magnetic active composite material structure printing device. Background technique [0002] Magnetic actuation based on magnetically active composites is a promising emerging actuation method because it is a non-contact form of energy transfer that allows unconstrained control and is considered as a non-contact method for biomedical applications. Bacteria drive method. It has important application prospects in the field of microsoft robots and microfluidic chips for medical applications such as drug delivery and minimally invasive surgery. [0003] Magnetically active elastomers (MAEs) are commonly used magnetically active composite materials, mainly by dispersing magnetic micro-nano particle fillers (such as NdFeB, Fe3O4 particles, etc.) into soft elastic materials (such as Ecof l ex, Magnetically active elastic hybrids made in PDMS, etc.). The magnetically active elastomer is induced by an external magnetic field to prod...

Problems solved by technology

However, this manufacturing method has some disadvantages, such as uneven dispersion and easy agglomeration of magnetic particles in soft elastic materials, and solidification in a strong magnetic field environment is likely to lead to insufficient, uneven, and discontinuous functional orientation of magnetic particles. Leading to poor deformation ability of magnetically active elastomers induced by external magnetic field
