Polymer Powder, Method For Producing Same And Method For Producing 3

Polymer Powder, Method For Producing Same And Method For Producing 3 Dimensional Model Object

Abstract: A polymer powder composed of a polyamide, characterized in that the melting point obtained by differential scanning calorimetry is 190°C or higher, the difference between the melting point and the melting start temperature obtained by differential scanning calorimetry is less than 30°C, and the D50 particle size is 1-100 µm inclusive; a method for producing the same; and a method for producing a 3-dimensional model object through a powder bed melt bonding process using the same. The polymer powder of the present invention can maintain the powder form in a non-laser irradiated area even in a large modeling device. By using the polymer powder in the production of a model object, a model object having small warpage can be provided.
