CISE Research Instrumentation: Acquisition of a Rapid Prototyping System

CDA-9529346 Peter K.Allen Gerard Ateshian Van C.Mow John Kender哥伦比亚大学收购快速原型系统快速原型(RP)机器为开发“3-D传真”创造了机会，它可以将物理物体的模型传输到另一个可能重建的地点。最初的目标是自动化模型扫描过程，减少当前系统的时间、成本和操作员干预需求。该项目还解决了影响3D传真的模型获取、传感器规划和数据压缩方面的系统问题；如果没有拟议的RP机器，这项工作将无法进行。第二个项目是在假体设计中使用RP机器。各种各样的身体关节可以用立体摄影测量、CT和MRI进行成像，以产生模型原型。然后，可以用快速成型设备建立这些模型，并进行实验测试，以验证它们适合不同的个体并产生正常的关节力学。我们的目标是采用完成上述任务所需的成像工具，并将它们与RP设备集成，以形成一个有效的、经临床验证的过程。第三个项目是创建具有不同表面深度的对象，以测试使用多个光源的形状恢复方法。该设备允许生产指定具有不寻常表面配置的不同对象，以适当地测试和评估重建方法。

CDA-9529346 Peter K. Allen Gerard Ateshian Van C. Mow John Kender Columbia University Acquisition of a Rapid Prototyping System Rapid-Prototyping (RP) machines have created an opportunity for development of a "3-D FAX" which can transmit a physical object's model to another site where it may be reconstructed. The initial goal is to automate the model scanning process, reducing the time, cost and operator intervention needs of current systems. The project also addresses system issues in model-acquisition, sensor-planning, and data- compression that affect 3-D FAX; without the proposed RP machine this cannot proceed. A second project is to use the RP machine in prosthesis design. A large variety of cadaver joints can be imaged with stereophotogrammetry, CT, and MRI to produce model prototypes. These models can then be built with RP equipment and tested experimentally to verify that they adapt to different individuals and produce normal joint mechanics. The goal is to take the imaging tools required to perform the tasks outlined above and integrate them with RP equipment to form an efficient and clinically proven process. The third project is to create objects with varied surface depth to test a shape recovery method using multiple light sources. The equipment allows production to specification of different objects with unusual surface configurations to properly test and evaluate the reconstruction method.
