Beschreibung
Zusammenfassung:	A resin powder contains a resin containing particles, wherein the proportion of the particles in an aspect ratio range X represented by the following inequality 1 is 50 percent by number or more in a number distribution of an aspect ratio of the resin powder: A50 - 1 ≤ X ≤ A50 + 1 Inequality 1, where A50 represents a median of the aspect ratio. Further disclosed is a method of manufacturing a solid freeform fabricated object comprising forming a layer comprising such a resin powder, irradiating the layer with electromagnetic wave to melt the layer and repeating the forming and the irradiating. Also disclosed is a device for manufacturing a solid freeform fabricated object comprising a supply tank (11) configured to accommodate such a resin powder, a layer forming device (12) configured to form a layer of the resin powder, and a melting device (18) configured to irradiate the layer with electromagnetic wave to melt the layer.
