Abstract
. As a proof of concept, we demonstrate the rapid fabrication of 3D-printed stents with intricate architectures, outstanding load-bearing capabilities, and excellent biocompatibility. This strategy not only paves the way for the development of mechanically robust, complex-structured PUEs but also broadens their application scope in engineering and biomedical fields.
