  • Publication number: 20220063187
    Abstract: When constructing parts by additive manufacturing, it is sometimes necessary to include a support structure during part fabrication, wherein the support structure is subsequently removable. Polymer filaments suitable for forming support structures during additive manufacturing may comprise a polymeric material, and a gas-forming substance admixed with the polymeric material in an effective amount to undergo effervescence when the polymeric material is in contact with at least one fluid comprising a liquid phase. Additive manufacturing processes may comprise forming a supported part by depositing a build material and a removable support (e.g., upon a print bed) formed from such polymer filaments, wherein at least a portion of the build material is deposited upon the removable support. Exposure of the gas-forming substance to a fluid in which the polymeric material dissolves or degrades may promote gas formation to facilitate elimination of the removable support by effervescence.
