摘要： The invention relates to a pulverulent composition comprising a powder based on at least one polyaryl ether ketone, said composition having at least a first endothermic peak and a second endothermic peak, the first endothermic peak having a peak temperature strictly greater than 280°C, and the second endothermic peak having a peak temperature equal to a value of 200°C to 280°C; the endothermic peaks are measured on a thermogram obtained by differential scanning calorimetry, according to the standard ISO 11357-3: 2018, on first heating, using a temperature ramp of 20°C/minute. The invention also relates to a method for the electromagnetic radiation-mediated layer-by-layer sintering construction of a three-dimensional object from the pulverulent composition, to a method for determining the minimum construction temperature to be used, and also to objects that may be manufactured via this construction process.
