3D Filament printing of thermoreversible thermoset filaments with a delayed cure

Detailed Technology Description: Invention: Filaments made of a thermoreversible thermoset based on Diels Alder cycloadductsare used in 3D filament printing to create 3D artifacts that will irreversibly cure via reaction ofreactive diene or dienophile components. This allows filaments to be made and a thermoset tobe formed in the final printing. Applications: • 3D Printing, prototyping, custom manufacturing, wide variety of industries.• 3D Printing allows for quick and inexpensive production of custom structures• Melt-processable thermoplastics have inferior properties to thermosets• 3D Printable thermosets expand the range of useful objects that can be made Advantages:• Thermoset materials are stronger and more robust than thermoplastics• More uniform curing possible with thermal cure instead of photo cure• New material could be used as a spooled filament feedstock instead of tanks of messy liquid precursor.• Possibly less prepolymer waste Licensing Manager:Robert Sleeperemail@tla.arizona.edu520-626-4604
