Description

technical field

[0001] The invention relates to the technical fields of additive manufacturing and 3D printing, in particular to an electric field-driven spray deposition 3D printing device and a working method thereof. Background technique

[0002] Material jet deposition 3D printing is an additive manufacturing method that selectively deposits forming materials based on the principle of droplet jetting. At present, a variety of material jet deposition 3D printing technologies have been proposed in the world, mainly including inkjet (thermal bubble or piezoelectric) printing. , aerosol jet (aerosol jet), polymer jet (PolyJet), nanoparticle jet technology (NanoParticle Jetting), etc. However, these traditional materials are limited by spray deposition forming materials, usually require printing materials with low viscosity (usually less than 100cP), the types of materials available for printing are limited, and the printing resolution is not high. It is still difficult to ac...
