Rapid prototyping by curing polymers with laser light has created considerable interests in industry to generate three dimensional parts directly from Computer Aided Design (CAD) drawings to aid design processes. Laser cladding by layers offers the possibility of fabrication of 100% dense metal component. The objective of this research is to develop a Laser Aided Metal Deposition System (LAMDS) capable of forming near 100% dense three-dimensional objects directly from CAD drawing. The project will develop a fundamental understanding between the process parameters for laser aided metal deposition of H13 steel with deposit dimension with 10-100 micron accuracy, microstructure and mechanical properties. The research project has a balance between theory and experiment, and will provide valuable findings for the tools and dies manufacturing industry.

通过激光固化聚合物的快速原型制造已经在工业中引起了相当大的兴趣，可以直接从计算机辅助设计（CAD）图纸中生成三维零件，以辅助设计过程。激光分层熔覆提供了制造100%致密金属部件的可能性。本研究的目的是开发一种激光辅助金属沉积系统（LAMDS），能够直接从CAD图纸中形成接近100%的致密三维物体。该项目将对激光辅助金属沉积H13钢的工艺参数、微观结构和力学性能有一个基本的了解，沉积尺寸为10-100微米。本研究项目理论与实验相结合，将为模具制造行业提供有价值的研究成果。
