Zusammenfassung:A recently developed electrohydrodynamic printing method is described that can be used to create ordered structures and complex patterns using coarse processing needles and two polymeric materials. The results highlight the method's potential for direct 3D writing of biomedical polymers and composites for a variety of biomedical applications. Direct write patterning of polymer‐based architectures using a coarse needle and electrohydrodynamic flow is described. Fine architectures comprised of polyurethane and poly(methylsilsesquioxane) were generated in a controlled manner to fabricate a specified pattern. These structures are significantly smaller than the processing needle orifice and are made possible by the action of an electric field. Without the use of the patterning method the resultant structures would be similar to those obtained using simple electrospinning.
