Abstract
A method of ink-extrusion printing an object, including providing a mixture including liquid crystal monomers and photo-catalyzing or heating the mixture to produce a liquid crystal ink. The ink is in a nematic phase. The method includes extruding the ink through a print-head orifice moving along a print direction to form an extruded film of the object. The extruded film exhibits birefringence. Also disclosed are a liquid crystal ink. The ink includes a mixture including liquid crystal monomers. The mixture when at a target printing temperature is in a nematic phase. Also disclosed is ink-extrusion-printed object. The object includes an extrusion-printed film including a nematic liquid crystal elastomer, wherein the film exhibits birefringence along an extrusion axis of the film.
