NOVELTY - Magnetically controlled 3D printing UV curable conductive material comprises 5-15 pts. wt. oligomer, 25-60 pts. wt. active monomer, 5-15 pts. wt. magnetic nano-graphene, 0.01-0.2 pt. wt. polymerization inhibitor and 1-10 pts. wt. photoinitiator. USE - As magnetically controlled 3D printing UV curable conductive material. ADVANTAGE - The conductive material adopts 3D printing method that realizes positioning through light curing exposure and can be used in application of flexible circuit board 3D printing manufacturing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the conductive material involving (i) mixing the above material at a water temperature of 40-50 degrees C, ultrasonically cleaning with an ultrasonic cleaner for 50-120 minutes, placing in a homogenizer and uniformly stirring to obtain a magnetron 3D printing UV-curable resin, (ii) putting the magnetic control 3D printing UV curing resin into a liquid tank in digital light processing/stereolithography/LCD (DLP/SLA/LCD) 3D printing device, adopting the DLP/SLA/LCD imaging system and fine electromagnetic field control system, secondarily arranging and assembling the magnetic nano-graphene in the magnetic control 3D printing UV curing resin under the action of an electromagnetic field to form a conductive path to achieve conductivity ( sigma ) of 106-108 s/m, (iii) curing the other components of the 3D printing UV curing resin by UV to cure a thin layer of resin at a time and curing of the magnetic nano-graphene in the thin layer resin by fine electromagnetic field control and aggregation and (iv) lifting up each cross-section after the exposure is completed through a lifting device above the liquid tank, so that the current curing completed solid resin is separated from the bottom surface of the liquid tank and bonded to the lifting plate or the last-formed resin layer and finally, generating three-dimensional entity by layer-by-layer exposure and lifting and obtaining the cured and formed magnetic control 3D printing UV curable conductive material.
