Composite 3D printing
Featured snippet from the web
Composite fibers boost specific properties of traditional 3D printed parts - usually strength, stiffness, heat resistance, and durability. ... This makes them popular 3D printing materials because they can easily be melted, extruded layer by layer, and immediately cooled into a shape.
Most 3D printers capable of processing composite materials are based on the polymer-extrusion process, known as Fused Filament Fabrication (FFF). ... 3D printing of filaments containing chopped fibres is straightforward, only requiring a hardened steel nozzle to resist abrasive fibre strands
