3D-Graphite paint can be 3D-printed at room temperature into multi-layered, three dimensional objects. The resulting extruded material rapidly solidifies, allowing for complex, user-designed forms to be created.
3D-Graphite 3D-Paint (3DG-R1A)
This research grade (not for human use) 3D-Graphite 3D-paint can be 3D-printed at room temperature using a direct extrusion (pneumatic or mechanical) 3D-printer into multi-layered, three-dimensional objects. The 3D-paint should only be used in a well-ventilated environment. The resulting extruded material rapidly solidifies, allowing for complex, user-designed forms to be created. The resulting solid material is electrically conductive and flexible depending on the printed architecture. The solids loading of the as-dried material is 75 wt.% graphite powder and 25 wt.% polylactide-co-glycolide (PLG). 3D- Graphite microstructural, mechanical, physical, and biologic properties are similar to 3D-Graphene, however, 3D-Graphite is ~45% less conductive than its 3D-Graphene counterpart. In its solid, washed state, fine 3D-Graphite fibers (100-400 μm in diameter) exhibit a conductivity of approximately 350 S/m. 3D-Graphite 3D-paint can be utilized to create three-dimensional structures, two-dimensional patterns on appropriate substrates, such as PLG films, or co-3D-printed with other 3D-paints to create multi- material structures. 3D-Graphite 3D-paint may also be mixed with other 3D-paints to create compound 3D-paints prior to utilization. Due to the mechanical flexibility of the material after drying, complex 2D and 3D forms can be created. 3D-Printed 3D-Graphite can be rolled, cut, folded, and punched as desired. It may even be sutured to itself or to soft tissues. The 3D-Graphite 3D-paint may also be utilized in non- 3D-printing applications such as coating (dip-coating or direct painting), thread fabrication, or casting into molds.
After 3D-printing or other application, 3D-Graphite should be washed in 70% ethanol or 70% isopropyl alcohol followed by water, to remove residual solvents, prior to use. It can be utilized in this form, as a flexible, bioactive, electrically conductive biomaterial. 3D-Graphite has numerous electrogenic tissue (nerve, muscle, cardiac) repair and regeneration applications as well as flexible bioelectronic and wearables applications. 3D-printed 3D-Graphite can serve as an effective cell scaffold for in vitro or in vivo use.
