(1) This project is about the prediction of selective laser melting (SLM) spreading powder process based on the discrete element method (DEM) code Yade. The project "differentScraperSpreadPowderSLM_Yade" is about the spreading powder process under different scraper scenarios; the project "multiLayerSpreadPowderSLM_Yade is about the spreading powder processes of different layers.

(2) This project is all based on the discrete element method (DEM) code Yade expansion, therefore, you need to install Yade before the calculation (just refer to the official Yade instructions, link: https://yade-dem.org/doc/installation.html).

(3) Please refer to the documents "differentScraperSpreadPowderSLM_Yade/Instruction for Predicting the Spreading Powder Process with Different Scraper by Using Yade.pdf" and "multiLayerSpreadPowderSLM_Yade/Instruction for Predicting SLM Multi-Layers Spreading Powder Process by Using Yade.pdf" for the exact calculation processes.

（1）本项目是关于：基于离散单元法（DEM）代码Yade，预测激光选区熔化（SLM）铺粉过程。其中，项目“differentScraperSpreadPowderSLM_Yade”是关于不同刮板情形下的铺粉过程；项目“multiLayerSpreadPowderSLM_Yade”是关于不同层的铺粉过程。

（2）本项目均基于离散单元法（DEM）代码Yade展开，因此，计算前需要先安装Yade（参照Yade官方说明即可，链接：https://yade-dem.org/doc/installation.html）。

（3）具体计算流程请分别参照文档“differentScraperSpreadPowderSLM_Yade/Yade预测不同刮板情形下铺粉过程说明.pdf”和文档“multiLayerSpreadPowderSLM_Yade/Yade预测SLM多层铺粉过程说明.pdf”。
