Interesting that this is a thermoplastic - my first question is how it performs as a 3D printer filament?

The researchers are wondering, too. Last sentence in the abstract:

> This approach can be extended to polysaccharide-based supramolecular plastics that are applicable for three-dimensional printing.

(So, they haven't done it yet, but are thinking about it.)

second question - does it/will it cost like $500 per 1kg spool?
