Figure 1: Schematics of the MM-3D printing platform for the creation of heterogeneous composites.
From: Multimaterial magnetically assisted 3D printing of composite materials
(a) Direct ink-writing hardware equipped with multiple dispensers (I), a mixing unit (II), movable head and table (III), a magnet (IV) and a curing unit (V). (b) Example of MM-3D printed object designed to change shape on external stimulus. Different inks were formulated to results in (VI) a stiff material, (VII) a soft swelling material, (VIII) an anisotropic reinforced material, and (IX) a support material. (c–e) Illustrations of typical ink constituents. (c) Oligomers and monomers that form the base material and are crosslinked after deposition to generate a polymer network. (d) FS nanoparticles that percolate throughout the resin. (e) Anisotropic particles oriented by the external magnetic field. (f) chemical structures of typical ink monomers/oligomers. (g) SEM image of fumed silica particles. Scale bar, 500 nm. (h) SEM image of alumina platelets. Scale bar, 10 μm.
