Determining The Print Accuracy Of Four Three-Dimensional Printers, Kshiteej Dalal
Master of Technology Management Plan II Graduate Projects
Rapid prototyping [RP] or 3D printing [3DP] have existed for some time now. One of the major deficiencies of 3DP is the accuracy of the printed three dimensional parts. Even beyond that is the lack of studies that have been designed to measure the 3DP components. Measuring, verifying and determining the accuracy of 3DP parts is the focus of this study. As the accuracy is measured and approaches those of CNC machined parts, it will drive the development of additional additive manufacturing [AM] machinery. In this project a component is created in a solid modeling package. A solid model of …

In this work, we develop a scalable end-effector mechanism for grasping three- dimensional objects with sizes ranging from micrometer to millimeter scale. The design architecture of the gripper comprises an array of identical fingers patented in a circular fashion. Each finger is designed from a novel linkage mechanism whose end effector is manipulated by two independent actuators. In this research, we study three finger gripper device, where each is obtained from a 3 - linkage mechanism. The device is controlled by three independent piezo actuators, and one electro-magnetic solenoid common to each mechanism. The gripping capability depends on how fingers …
