The proposed study is concerned with a one-step direct process to fabricate three-dimensional parts using a laser beam. This process is referred to as the Laser-Aided Direct Rapid Prototyping (LADRP). Laser light can melt and/or vaporize virtually any material and laser tooling leads to the unification of various conventional tools because a laser beam can be used to carry out many different machining operations such as cutting, drilling, welding and milling. Such process integration is very important for the rapid production of three- dimensional parts directly in near net shape. The success of the proposed rapid prototyping process depends on the development of systematic design methodologies and developing suitable digital interfaces between design and manufacturing. The proposed research will carry out experimental studies and develop mathematical models for the LADRP process, and will develop design rule characterization of the LADRP process so that lower- level CAD tools for process planning simulation and verification may be implemented. A layered description language will be developed that can generate the slices of 2.5 D layers for the part from an input file specified in some higher level description language such as the STL or ACIS format.

拟议的研究涉及使用激光束制造三维零件的一步直接工艺。 此过程称为激光辅助直接快速原型制作 (LADRP)。 激光几乎可以熔化和/或汽化任何材料，激光加工可以实现各种传统工具的统一，因为激光束可用于执行许多不同的加工操作，例如切割、钻孔、焊接和铣削。 这种工艺集成对于直接以近净形状快速生产三维零件非常重要。 所提出的快速原型制作过程的成功取决于系统设计方法的发展以及设计和制造之间合适的数字接口的开发。 拟议的研究将开展实验研究并开发 LADRP 过程的数学模型，并将开发 LADRP 过程的设计规则表征，以便可以实施用于过程规划模拟和验证的较低级别 CAD 工具。 将开发一种分层描述语言，它可以从以某些高级描述语言（例如 STL 或 ACIS 格式）指定的输入文件生成零件的 2.5 D 层切片。
