Program: Rapid Prototyping Demonstration
Host: Dr. Bill Ryan, OC Mech. Engr. Faculty Member
Location: Oklahoma Christian University
Prince Engineering Center, 2501 E. Memorial Road, Edmond, OK
Rapid Prototyping (RP) is a group of techniques used to quickly fabricate a scale model of a part or assembly using three-dimensional computer aided design (CAD) data. The first RP technique, Stereolithography (STL), was developed by 3D Systems of Valencia, CA in 1986. Since then a number of different RP techniques have become available.
Rapid Prototyping is also referred to as solid free-form manufacturing, computer automated manufacturing, and layered manufacturing. RP has obvious use as a vehicle for model visualization. In addition, RP models can be used for testing, such as when an airfoil shape is put into a wind tunnel, or for tooling, such as silicone rubber molds and investment casts. RP parts may occasionally be used as final parts, but they typically lack strength and accuracy. When the RP material is suitable, highly convoluted shapes (including parts nested within parts) can be produced because of the nature of RP.
The basic methodology for all current rapid prototyping techniques may be summarized as follows:
1. A CAD model is developed, then converted to STL format. The resolution can be set to minimize stair-stepping.
2. The RP machine processes the STL file by creating sliced layers of the model.
3. The first layer of the physical model is created. The model is then lowered by the thickness of the next layer, and the process is repeated until the model is completed.
4. The model and any supports are removed. The model surface is then finished and cleaned.
Our speaker and host will be Dr. Bill Ryan, picutured at left. Dr. Ryan, a member of the Oklahoma Christian University (OC) Mechanical Engineering faculty, also serves as co-Faculty Advisor of OC's ASME Student Section. Dr. Ryan achieved a B.S. degree in Physics from California State College, an M.A. degree in Physics from Sam Houston State University, and a Ph.D. in Mechanical Engineering from the University of Texas.
Per Professor Ryan: "I enjoy watching students come to life within the Christian environment." He is a member of the Acoustical Society, the American Society for Mechanical Engineers, and he serves as sponsor for OC's Society for Automotive Engineers student group.
Dr. Ryan is interested in noise and vibration analysis, church building acoustics, and energy analysis. He is the co-Chair for Francis-Tuttle Pre-Engineering program. Dr. Ryan enjoys amateur radio and farming with horses and cattle. He and his wife Wilma have two children: Catherine Bradley, and William Wade Ryan III. Dr. Ryan is an elder at Luther Church of Christ. He is also a Bible class teacher, he is on the Board of Directors for the Luther Community Center, and he also preaches as needed.
