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...

3D Filament Printing of Thermoreversible Thermoset Filaments with a Delayed Cure
Filaments made of a thermoreversible thermoset based on Diels Alder cycloadducts are used in 3D filament printing to create 3D artifacts that will irreversibly cure via reaction of reactive diene or dienophile components. This allows filaments to be made and a thermoset to be formed in the final printing. Applications: 3D Printing, prototyping,...
