Liquid crystalline polymer blends have long been proposed as potent recipes for the design of high performance molecular composites.  The liquid crystalline polymer can indeed serve the double function of lubricant for the processing of the blend as well as structuring agent in the final composite. In this presentation, our efforts at developing liquid crystalline polymer blends for direct ink writting of organosolv lignin multiphase materials will be reviewed. These efforts reveal that the lyotropic hydroxypropyl cellulose fulfills the two functions of lubricant agent for 3D printing of organosolv lignin as well as structuring agent in the final multiphase material.  Perspectives on future research routes for the development of fully bio-based polymeric inks for 3D printing will be discussed.
