摘要： Provided is an insert adapter for direct ink writing printers (DIW) and methods of fiber alignment in direct ink writing. The insert adapter is sized to fit snugly inside a print barrel DIW 3D printer. The adapter includes channels. The DIW printer with insert adapter, can be used in a passive method for microfiber alignment in DIW printing. The method includes feeding a non-Newtonian ink including microfibers through the print barrel such that the ink flows into the channels of the insert adapter before exiting through a print nozzle, causing the microfibers to align along the direction of ink flow.
