Abstract
A powder composition suitable for use in laser sintering for printing a three-dimensional object. The powder composition includes a polyaryletherketone (PAEK) powder having a plurality of particles. The plurality of particles having a mean diameter of D50. The composition includes a plurality of carbon fibers having a mean length L50. L50 is greater than D50. The particles are substantially non-spherical. A portion of the carbon fiber is embedded into the particle via high intensity mixing.
