Abstract
This invention relates to a method of evaluating a squeegeeing property of powder for lamination shaping by stable criteria. In this method, the squeegeeing property is evaluated using at least a satellite adhesion ratio of the powder and an apparent density of the powder. The satellite adhesion ratio is the ratio of the number of particles on which satellites are adhered to the number of all particles. If the satellite adhesion ratio is equal to or less than 50%, and the apparent density is equal to or more than 3.5 g/cm, the squeegeeing property is evaluated as that the powder can be spread into a uniform powder layer in the lamination shaping. Furthermore, if the 50% particle size of a powder obtained by a laser diffraction method is 3 to 250 μm, the squeegeeing property is evaluated as that the powder can be spread into a uniform powder layer in the lamination shaping.
