    摘要： A method for producing a twin screw cylinder provided with or having a wear-resistant coating, in which two bores, which extend essentially parallel to each other and overlap each other, are produced in a cylinder and then two liners are inserted into the bores, the liners having an essentially C-shaped cross-section, continuing from each other in the overlapping region of the bores, forming the inner surface of the bores, and serving as a wear-resistant coating. First, a tubular liner is inserted into a first bore and then is cut to form the C-shaped cross-section in accordance with the diameter of the other bore and after this, a second tubular liner is inserted into the second bore and then is cut to form the C-shaped cross-section in accordance with the diameter of the inner surface in the first bore formed by the first liner.

    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.
