Abstract: In one instance a semicrystalline polyketone powder useful for additive manufacturing is comprised of a bimodal melt peak determined by an initial differential scanning calorimetry (DSC) scan at 20° C./min and a D90 particle size of at most 300 micrometers and average particle size of 1 micrometer to 150 micrometers equivalent spherical diameter. In another instance, A composition is comprised of a semicrystalline polyketone powder having a melt peak and a recrystallization peak, wherein the melt peak and recrystallization peak fail to overlap.

Abstract: Spherical thermoplastic polymer powders useful for additive manufacturing may be made at high throughputs by a method comprising polymer in a dispersing medium at a temperature above the polymer melting temperature (Tm) under shear for short times (e.g., less than 30 minutes) to form a mixture that is then rapid (faster than ambient cooling) cooled below Tm. The method is particularly useful for thermoplastic polymers having a high melt flow index (MFI) or low capillary viscosity at high shear (˜1000 s−1) within 20 or 30° C. of the polymer's melt temperature. The method may also include a crystallizing temperature below Tm and above the glass transition temperature Tg of the polymer to crystallize amorphous polymers or increase the crystallinity of semi-crystalline polymers.

Abstract: An additive manufactured condensation polymer article with improved build or Z direction strength may be formed by physically mixing or depositing thereon a chain extender that extends and chemically bonds the polymer chains within and between layers upon heating and fusing during the additive manufacturing process.

Abstract: A semi-crystalline blended polymer useful for additive manufacturing is comprised of an amorphous thermoplastic polymer and a thermoplastic semi-crystalline polymer, each of the polymers being essentially miscible in the other and being blended at a weight ratio of amorphous polymer/semi-crystalline polymer of greater that 1 to about 20. The semi-crystalline blended polymer displays a DSC melt peak enthalpy of at least about 3 joules/g. The semi-crystalline polymer may be made by blending the aforementioned polymers at the weight ratio and subject to heating between the melt temperature of the semi-crystalline polymer and the glass transition temperature of the amorphous polymer. The semi-crystalline blended polymer may revert to essentially an amorphous polymer when additive manufactured by fusing layers of said polymer powders together.

Abstract: An additive manufacturing composition useful as a support material for common build materials (e.g., polyamide or polyester) is comprised of a blend of an elastomer toughened styrenic polymer having discreet domains of polymerized conjugate diene dispersed within a styrenic matrix and a vinyl aromatic-maleic anhydride copolymer. The composition may be used as a support material in additive manufacturing methods such as extrusion methods (e.g., fused filament fabrication). The compositions may be tuned to realize the desired adherence to facilitate the desired support while also allowing for the mechanical removal without breakage of the underlying part or residual adhered support material.

Abstract: A composition useful for additive manufacturing is comprised of a thermoplastic elastomer blended with an aliphatic polyketone, wherein the thermoplastic elastomer is a continuous phase having dispersed therein separated domains of polyketone. The composition is useful for additive printing methods employing heating and extrusion of the composition to form extrudates that are printed an article comprised of fused layers of the composition. The composition facilitates the formation of extrusion based elastomeric additive manufactured articles.

Abstract: Useful thermoplastic polymer powders are formed by a method comprising: cooling a foam comprised of a thermoplastic foam below the brittleness temperature of the thermoplastic polymer, wherein the foam has an average strut dimension of 10 to 500 micrometers, and comminuting the cooled foam to form a thermoplastic polymer powder. The method allows for the efficient grinding of the thermoplastic polymer having improved morphology and desirable characteristics such as dry flow without flow aids.
