摘要
The material-extrusion based forming technology is a 3D printing way that enables rapid printing of various functional inks. Due to the complex rheological properties of these inks and multiple processing parameters of the material-extrusion based 3D printing, how to precisely control the printing line morphologies with specified finer width is of high challenge. Aiming at this problem, the crucial processing parameters are probed and then combined to establish two normalized variables of motion speed and height for extrusion nozzle, which is revealed to dominate the morphologies of the printed lines. In particular, a phase diagram governed by the two normalized variables is constructed, providing an integrated scope for setting the processing parameters to achieve controllable morphology and width of the printing line. Guided by the phase diagram, a chain with complex morphology and multi functions is continuously printed by controlling processing parameters. This work provides insights for rapidly printing complex patterns with high-resolution and multi-functions.
