Abstract: Compositions useful for making additive manufactured articles are comprised of a styrenic thermoplastic elastomer, the styrenic thermoplastic elastomer being comprised of a block copolymer being comprised of at least two blocks of a vinyl aromatic monomer and at least one block of a conjugated diene monomer, and a solid particulate filler dispersed therein, wherein the filler has a surface area of 0.05 m2/g to 120 m2/g. The compositions may be formed into filaments for use in fused filament fabrication additive manufacturing. The filaments display good printability without drying or storage under dry conditions.

Abstract: A semicrystalline polyketone powder useful for additive manufacturing may be made by dissolving a polyketone having differential scanning calorimetry (DSC) monomodal melt peak, at a temperature above 50° C. to below the melt temperature of the polyketone, precipitating the dissolved polyketone by cooling, addition of a nonsolvent or combination thereof. The method may be used to form polyketones having a DSC melt peak with an enthalpy greater than the starting polyketone.
