The present invention generally relates to a powder comprising a PEEK-PEoEK copolymer, wherein the PEEK-PEoEK copolymer having Rand Rrepeat units in a molar ratio R/Rranging from 95/5 to 5/95. The present invention also relates to a method of preparing a three-dimensional (3D) object by sintering layers of the powder.

PEEK-PEoEK copolymer powder and method of preparing the powder

The present disclosure relates to an additive manufacturing (AM) method for making a three-dimensional (3D) object, using a part material (M) comprising at least one poly(ether ketone ketone) (PEKK) polymer, in particular to a 3D object obtainable by Fused Deposition Modelling (FDM) or Fused Filament Fabrication (FFF) from this part material (M).

Additive manufacturing method for making a three-dimensional object

The present invention generally relates to a powder comprising a PEEK-PEoEK copolymer, wherein the PEEK-PEoEK copolymer having Rand Rrepeat units in a molar ratio R/Rranging from 95/5 to 5/95. The present invention also relates to a method of preparing the powder, as well as to the uses of the powder for coating, compression molding and to prepare a three-dimensional (3D) object.

Described herein are polymer compositions including at least one semi-crystalline, semi-aromatic polyester polymer and at least one impact modifier. The blends have excellent impact resistance and excellent dimensional stability. The blends also have excellent chemical resistance, whiteness, colorability and anodization resistance. The polymer compositions can optionally include at least one amorphous polymer. The at least one amorphous polymer can be an amorphous polycarbonate polymer or an amorphous polyester polymer or a polyester-carbonate. In some embodiments, the polymer composition can optionally include one or more additives. The polyester compositions described herein can be desirably incorporated into mobile electronic device components.
