Invention:

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, 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
