The present disclosure relates to a silk-fibroin ink suitable for 3D printing. The ink for 3D printing now disclosed may be used in chemical and pharma industries, medicine, engineering, manufacturing namely for the production of capsules, fibres, membranes, particles, scaffolds, medical devices, microfluidic devices and patient-specific implants.

Inks for 3D printing, methods of production and uses thereof

The present disclosure relates to a composition for the release of the bioactive substance comprising: sucrose acetate isobutyrate dissolved in an ionic liquid and an additive selected from the list consisting of: chitin, silk fibroin, cellulose, alginate, chitosan, gellan gum, dextrin, collagen, guar gum, carregeenan, heparin, kefiran, or mixtures thereof. By taking advantage of the properties of an ionic liquid (IL), in particular 1-butyl-imidazolium acetate (BMIMAc), it was possible to achieve a good dissolution of SAIB, which combined with chitin and/or silk, natural polymers, allows the development of the structures with different shape and sizes.
