Abstract

A method of manufacturing filters from regolith or 3d printing metal residues is presented, the method comprising (a) laying down a layer of particles of regolith or 3d printing metal residues into a mold; (b) closing the mold; (c) in-mold processing the regolith or 3d printing metal residues present in the mold by injecting pressurized gas into the mold and heating up the under-pressure regolith or 3d printing metal residues to exert the particles of regolith or 3d printing metal residues to fuse at least partially with each other without regolith or 3d printing metal residues melting; (d) decreasing temperature in the mold, depressurizing the mold, and opening the mold; repeating steps (a) to (d) at least once, wherein the particles of regolith or 3d printing metal residues of the step (a) are laid over the in-mold-processed regolith or 3d printing metal residues; and following the in-mold processed regolith or 3d printing metal residues reaching a desired parameter, demolding the in-mold processed regolith or 3d printing metal residues to obtain the regolith or 3d printing metal residues filter.
