To summarize, in the RUP, the quality of the latest increment is verified in every iteration.
概括地说，在RUP中，每一次迭代都要检验上一次增加的质量。

The goal is to never let quality erode, thus ensuring that a high-quality useful product increment is produced at the end of the iteration.
我们的目标就是永远保证质量不出现问题，从而确保在迭代结束时生产出一个高质量的可用的产品增量。

The technics parameters, such as the laser power, scan velocity, powder feed rate and the Z axis increment, which influence quality and shape were analyzed in this article.
