Abstract
A process for the layer-by-layer manufacture of a three-dimensional object by sintering of a powder based on PAEK(s) with electromagnetic radiation, wherein the powder includes at least one PAEK and at least one phosphate, said powder being, at least in part, a recycled powder. The recycled powder is obtainable by continuous or discontinuous heating, over a period of at least six hours, of a powder of the same composition at a constant or nonconstant temperature, strictly between the glass transition temperature, Tg, and the melting temperature, Tm, of the powder. Also, an article obtained by this process and to uses of phosphate(s) in compositions based on PAEK(s).
