We propose a method to create aligned porosity in injectable materials by using magnetically responsive microrods as pore forming sacrificial templates. Rod alignment occurs through the application of an external magnetic field after injecting the material into the desired end location. Removal of the sacrificial templates through dissolution or resorption generates porosity in deliberately tuned orientations after injection, offering a powerful method to design the porous architecture of injectable materials.
