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.

摘要： Descriptive abstract: A powder composition of polyarylene ether ketone ketones allowing an excellent castability/coalescence balance suitable for laser sintering. The present invention concerns a composition comprising between 99.6 and 99.99 % by weight of at least one powder of at least one polyarylene ether ketone and 0.01 to 0.4% by weight of a hydrophilic flow agent. This hydrophilic flow agent is characterised by an increase in mass (quantity of water absorbed) of more than 0.5% after 5 days of conditioning at a relative humidity of 95%. This increase in mass of the flow agent is determined by means of a Karl Fischer measurement after desorption of the water by a 5-minute treatment at 170°C. This composition is suitable for laser sintering. In particular, it gives the powder an excellent castability/coalescence balance.
