ALUMINIUM POWDER FOR FORMING 3D OBJECTS AND METHOD FOR PRODUCING 3D OBJECT

A powder for forming 3D objects includes a group of particles having an identical composition. The group of the particles includes 50% by mass or greater of aluminum. An oxygen content of the group of the particles is 950 ppm or less. A volume-based particle size frequency distribution of the powder...

Beschreibung
Zusammenfassung:	A powder for forming 3D objects includes a group of particles having an identical composition. The group of the particles includes 50% by mass or greater of aluminum. An oxygen content of the group of the particles is 950 ppm or less. A volume-based particle size frequency distribution of the powder for forming 3D objects has a peak top in a particle diameter range of 40 µm or greater and 70 µm or less, and a peak top in a particle diameter range of 10 µm or greater and 30 µm or less. A ratio (a frequency (%) of the peak top in the particle diameter range of 40 µm or greater and 70 µm or less)/(a frequency (%) of the peak top in the particle diameter range of 10 µm or greater and 30 µm or less) is 1.5 or greater.
