粉末床3D打印过程中球的随机堆积方法及其在键合建模中的应用

A Method for Random Packing of Spheres with Application to Bonding Modeling in Powder Bed 3D Printing Process

Travis J. Black, Alexei F. Cheviakov

摘要:

提出了一种基于Matlab的计算程序,以填充一个给定的体积与球的半径是随机挑选的任何指定的概率分布的\verb |Matlab|。一般程序序列和例子填充一个单位立方体,平行六面体,和凹域之间的两个半球形表面,球的半径从威布尔和伽玛分布,提出。考虑了在粉末床3D打印过程中由激光束加热的颗粒之间的键形成的数值模拟的示例应用。

英文摘要:

A Matlab-based computational procedure is proposed to fill a given volume with spheres whose radii are randomly picked from any specified probability distribution supported by \verb|Matlab|. The general program sequence and examples of filling a unit cube, a parallelepiped, and a concave domain between two hemispherical surfaces, with spheres whose radii are drawn from the Weibull and Gamma distributions, are presented. A sample application to the numerical modeling of bond formation between particles heated by a laser beam in powder bed 3D printing process is considered.
