Abstract: Systems and methods of support structures in powder-bed fusion (PBF) are provided. Support structures can be formed of bound powder, which can be, for example, compacted powder, compacted and sintered powder, powder with a binding agent applied, etc. Support structures can be formed of non-powder support material, such as a foam. Support structures can be formed to include inductive components that can be used to facilitate removal of the support structures in the presence of an external magnetic field. Additionally, support structures can be formed to break when a fluid, such as air or water, creates a force and/or pressure at a connection point interface.
