| Abstract Scope |
Low build time in Material Extrusion Additive Manufacturing (MatEx) is key to economically scalable printing of both large and small parts. A common approach used to overcome this issue today is to print larger roads at the cost of reduced geometric resolution and greater waste. The alternative approach of parallelization is limited by issues with geometric complexity, high cost, and machine design. We develop a new paradigm for parallelized MatEx of thermoplastics called Multiplexed Fused Filament Fabrication (MF3). MF3 simultaneously prints the same part or multiple parts with multiple FFF extruders without controlling each extruder’s motion, based on a continuous filament retraction and advancement strategy. MF3 can print non-periodic 3D structures, larger or smaller parts, unitary or distinct parts or a mixture of both, on the same machine, at a high throughput-resolution combination, without the limits of existing parallelization techniques. |
