Direct-ink-write printing of hydrogels using dilute inks
iScience, 2021 Direct-ink-write (DIW) printing has been used in myriad applications. Existing DIW printing relies on inks of specific rheology to compromise with printing process, imposing restrictions on the choice of printable materials. Reported ink viscosity ranges from 10-1 to 103 Pa·s.

Design of a Waterborne Polyurethane–Urea Ink for Direct Ink Writing 3D Printing [PDF]
Materials, 2021 In this work, polycaprolactone–polyethylene glycol (PCL–PEG) based waterborne polyurethane–urea (WBPUU) inks have been developed for an extrusion-based 3D printing technology. The WBPUU, synthesized from an optimized ratio of hydrophobic polycaprolactone diol and hydrophilic polyethylene glycol (0.2:0.8) in the soft segment, is able to form a physical ...
