Abstract
The present disclosure relates to method of making three-dimensional (3D) objects using an additive manufacturing system wherein the part material comprises a polymeric component comprising a poly(biphenyl ether sulfone) polymer (PPSU) having an optimized weight average molecular weight (Mw). In particular, the present disclosure relates to part material incorporating a PPSU of Mw ranging from 48,000 to 52,000 g/mol, for example in the form of filaments or spherical particles, for use in additive manufacturing systems to print 3D objects.
Claims19
A method of making a three-dimensional (3D) object, comprising:
- providing a part material comprising a polymeric component comprising at least one poly(biphenyl ether sulfone) (co)polymer (PPSU) having a weight average molecular weight (Mw) ranging from 48,000 to 52,000 g/mol (as determined by gel permeation chromatography (GPC) using methylene chloride as a mobile phase and polystyrene standards),
- printing layers of the three-dimensional object from the part material.
A filament material comprising a polymeric component comprising a poly(biphenyl ether sulfone) (co)polymer (PPSU) having a weight average molecular weight (Mw) ranging from 48,000 to 52,000 g/mol (as determined by gel permeation chromatography (GPC) using methylene chloride as a mobile phase and polystyrene standards).
A method for manufacturing a three-dimensional object using an additive manufacturing system or manufacturing a filament for use in the manufacture of a three-dimensional object, comprising using a part material comprising a polymeric component comprising at least one poly(biphenyl ether sulfone) (co)polymer (PPSU) having a weight average molecular weight (Mw) ranging from 48,000 to 52,000 g/mol (as determined by gel permeation chromatography (GPC) using methylene chloride as a mobile phase and polystyrene standards).
