Abstract: When making parts by additive manufacturing, particularly by fused filament fabrication, it is sometimes necessary to include a removable support during part fabrication due to the shape of the part. An overhang, for instance, may be fabricated using a support structure, which is subsequently eliminated following polymer matrix consolidation. Elimination of a removable support following part fabrication may be problematic in some instances. Polymer filaments suitable for forming removable supports during additive manufacturing may comprise at least one imide polymer having at least partial solubility in aqueous fluids. Imide polymers may include, for example, polyimides and polyesterimides. Additive manufacturing processes may comprise forming a supported part by depositing a build material and a removable support comprising an imide polymer, wherein at least a portion of the build material is deposited upon the removable support. An unsupported part may be formed following exposure of the supported part to an aqueous fluid.
