A one-step volumetric biofabrication platform for complex hydrogel-based hollow biomaterials
Rotational molding (RM) is a widely used industrial process for producing hollow polymeric structures, yet it remains largely unexplored for biomaterials fabrication. Here, a low-cost 3D-printed biofabrication platform is introduced that adapts the general concept of RM to generate tunable hollow constructs with high s...
