Abstract

Powder material from which three-dimensional object having high density and excellent shape retainability can be manufactured is provided. Powder material contains: first powder composed of first alloy; and second powder composed of pure metal or second alloy having composition different from first alloy. Difference (A-B) between melting point (A) of first powder and melting point (B) of second powder is ≥15°C and ≤200°C. Content of second powder is ≥7mass% and ≤30mass% relative to total amount of powder material. Area-weighted average grain size of sintered body obtained by sintering powder material at maximum temperature between melting points of first powder and second powder is less than 1.80 times volume average grain size of first powder, and/or, the first alloy is a titanium alloy which contains at least boron (B), or an aluminum alloy which contains at least one of chromium (Cr), zirconium (Zr), scandium (Sc), or manganese (Mn).
