Improved Fused Filament Deposition 3D Printing Using Filaments Coated With Thermoreversible Thermosets
This invention demonstrates a new polymer to coat the spool of thermoplastic filament used in fused deposition modeling (FDM) 3D printing with a thermoreversible thermoset. The goal is to provide a layer that will liquefy in the hot printer nozzle to produce a lower viscosity liquid polymer. This coats the melted filament and increases the wetting and...
