Particles are provided for use in layer-wise formation of components by selective sintering by electromagnetic radiation. The particles either consist essentially of 60 to 100% by weight of polyaryletherketone, PAEK polymer and 0 to 40% by weight of filler or are such particles with a shell consisting of secondary particles having a melting temperature which is greater than the melting temperature of the PAEK polymer. The particles have a total porosity from 0.58 to 0.40 5 derived from comparison of open pore volumes of a sample of the particles measured by mercury intrusion porosimetry at pressures of 0.33 psia (2.3 kPa) and 59950 psia (413.3 MPa) respectively. Components made from the particles by selective sintering by means of electromagnetic radiation exhibit improved properties.
