THREE-DIMENSIONAL (3D) PRINTED COMPOSITE STRUCTURE AND 3D PRINTABLE COMPOSITE INK FORMULATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240246284 titled 'THREE-DIMENSIONAL (3D) PRINTED COMPOSITE STRUCTURE AND 3D PRINTABLE COMPOSITE INK FORMULATION
Simplified Explanation: A filamentary structure extruded from a nozzle during 3D printing contains a continuous filament with filler particles dispersed within it. Some of these filler particles have a high aspect ratio and are oriented in a specific direction along the longitudinal axis of the filament.
- The filament in 3D printing contains filler particles with a high aspect ratio.
- Some of these particles are aligned along the longitudinal axis of the filament.
- The orientation of the high aspect ratio particles can be helical, with both circumferential and longitudinal components.
- The helical orientation is achieved through rotation and translation of the deposition nozzle.
Key Features and Innovation: - Continuous filament with filler particles - High aspect ratio particles with specific orientation - Alignment along the longitudinal axis - Helical orientation with circumferential and longitudinal components - Achieved through rotation and translation of the deposition nozzle
Potential Applications: - Enhanced strength and durability in 3D printed objects - Improved mechanical properties in printed parts - Tailored material properties for specific applications - Increased precision and control in 3D printing processes
Problems Solved: - Lack of strength and durability in traditional 3D printed objects - Inconsistent material properties in printed parts - Limited control over orientation of filler particles - Challenges in achieving desired mechanical properties in 3D printed objects

Original Abstract Submitted
a filamentary structure extruded from a nozzle during 3d printing comprises a continuous filament including filler particles dispersed therein. at least some fraction of the filler particles in the continuous filament comprise high aspect ratio particles having a predetermined orientation with respect to a longitudinal axis of the continuous filament. the high aspect ratio particles may be at least partially aligned along the longitudinal axis of the continuous filament. in some embodiments, the high aspect ratio particles may be highly aligned along the longitudinal axis. also or alternatively, at least some fraction of the high aspect ratio particles may have a helical orientation comprising a circumferential component and a longitudinal component, where the circumferential component is imparted by rotation of a deposition nozzle and the longitudinal component is imparted by translation of the deposition nozzle.
