CISE Research Instrumentation: Acquisition of a Rapid Prototyping System

哥伦比亚大学获得快速成型系统快速成型（RP）机器为开发“3-D FAX”创造了机会，它可以将物理对象的模型传输到另一个可以重建的地点。最初的目标是使模型扫描过程自动化，减少当前系统的时间、成本和操作人员干预需求。该项目还解决了影响3-D FAX的模型采集、传感器规划和数据压缩方面的系统问题；如果没有建议的RP机，则无法进行此操作。第二个项目是在假肢设计中使用RP机器。各种各样的尸体关节可以通过立体摄影测量、CT和MRI成像来产生模型原型。然后可以用RP设备建立这些模型，并进行实验测试，以验证它们是否适合不同的个体，并产生正常的关节力学。目标是采用执行上述任务所需的成像工具，并将其与RP设备集成，形成高效且经临床验证的流程。第三个项目是创建具有不同表面深度的物体，以测试使用多个光源的形状恢复方法。该设备允许生产部门指定具有不同表面结构的不同物体，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.
