SME 3D SCANNING EVENT TO TAKE PLACE IN MAY

DEARBORN, Mich., February 2, 2006 —The Society of Manufacturing Engineers (SME) 3D SCANNING: Reverse Engineering, Analysis, and Inspection Conference and Exposition will take place at the Marriott Renaissance in Detroit on May 1-2, 2007. This event is co-located with the RAPID 2007 Conference & Exposition.

With a focus on using non-contact scanning technology to capture and process high resolution 3D spatial geometries, this event will provide practical knowledge to support effective technology selection and use. A combination of case studies and interactive, problem-solving discussions will bring together industry leaders to provide the best information available.

The 3D SCANNING schedule:

Tuesday, May 1
1:30 p.m. - 4:15 p.m.
I Bought a New Scanner - What a Nightmare, and a Dream Come True
OK, you're ready to buy a scanner, or at least you think you are...where do you start? What's the first step? How do you cut through the sales speak and get to the bottom line of what the market scanners really can do? Go through the decision making process step by step to determine what scanner is truly the "best" for your application. Learn the right questions to ask of yourself and from the dealers. See data from many different technologies and learn about scanners that might work for you. This fast paced and fun presentation will give real examples and real numbers.
Mathew Cappel, Berding 3D Scanning

Creative and Non-Traditional Uses for Reverse Engineering Data
Using reverse engineering and scan data in non-traditional applications can maximize your products performance and customer appeal. The methods of how reverse engineering data is being used in tasks that include finite element analysis, generation of high-end visualization content and human anatomy modeling will be presented. Attendees will see real life case studies of how these techniques are being used in driving cutting-edge product development and marketing.
Jim Topich, Structural Analysis Engineering

Using 3D Scanning Tools for Aircraft Design Optimization
With the goal to reduce aerodynamic drag, the project started with 25 year-old techniques using plaster as a mold medium to create a new engine cowl. A laser scan of the airframe was performed with the cowling on the plane and with it removed, allowing the engine compartment to be analyzed for clearance between the cowling and the components already located inside. How this was done and the resulting design of ducts will be presented.

X-Ray Eyes: Can Tricorders be Far Away?
Examples of radiographic and CT imagery will be shown and the process of converting a CT volume to a surface will be described. Expectations for resolution, sensitivity, speed, throughput, and some practical considerations will be discussed. Acquisition and operating costs, what is practical and what is necessary, and the general kinds of work will be provided. Finally, a few thoughts about what the future may hold - tricorders are not that far fetched.
Martin Jones, Ford Motor Company

5:00 p.m. - 6:30 p.m.
Networking Reception
Ontario Room Join other attendees and exhibitors for a cocktail reception on the exhibit floor. This is your chance to catch up with old acquaintances, meet new ones and talk to industry leaders in a relaxed environment.

Wednesday, May 2
8:00 a.m. - 11:00 a.m.

3D Scanning: Industrial Applications
3D Part Validation and Beyond-Effective Use of DSSP
Many uses of point cloud generated by DSSP in the electromechanical manufacturing including: first article inspection, last article inspection (when tools are moved or changed), predictive tool wear, conversion of 2D legacy drawing to 3D databases by validating the generated CAD model as compared with the existing part, and more. An overview will be presented along with what benefits were realized throughout the entire enterprise.
Rus Emerick, Schneider Electric

Using 3D Laser Scanning to Reverse Engineer a Transmission Tailpiece
To secure a source of supply for Light Armored Vehicle (LAV) transmission tail piece housing (a large complex aluminum casting with numerous machined ports, bolt holes, hose connections, and flange surfaces), the part was reverse engineered using coordinate measuring machine (CMM) in combination with the 3D laser scanner. A process for combining the highly accurate CMM data with point cloud data generated by the laser scanner was developed. This combined data was then processed to create a solid model.
Michael Haselkorn, Rochester Institute of Technology

Modernizing Classic Casting Designs Through Reverse Engineering
The use of scanning technology to aid in rapidly developing new patterns of a tamper casting used by the railroad industry will be presented. Efficiently integrating scanned data with CAD model development to validate the design intent and meet short production schedules will be included. The reverse inspection process enables manufactures to validate final CAD models and eliminate manufacturing common casting errors such as shrinkage and warpage that are not addressed by typical scanning approaches.
Alvin Potter, Advanced Simulation Technology

3D Scanning: Medical Applications
3D Scanning Technologies as Applied to Medical and Human Body Applications
The current state-of-the-art applications and users, methods and techniques, equipment and tools, cost and benefits, and attempt to outline a vision for the increased use of 3D scanning technologies for the creation of customized medical prosthesis, orthotics, and other personalized body-conforming products will be presented. Various projects in collaboration with Juan Garcia, medical staff member at Johns Hopkins Hospital will be discussed.

Integration of Computed Tomography, Small Object Scanning and Motion in a Robust Diagnostic and Manufacturing Process for Dental Treatment
A computer model of a patient's jaws can be created on the basis of digital information from computed tomography and non radiographic digital imaging of the patient's teeth or dental casts of their teeth. Digital data of the jaws can be joined in computer space to reproduce the actual spatial jaw relationship of a patient and to eliminate scatter from radiation. A radiolucent jaw positioning device is used during computed tomography (CT) imaging to record the three-dimensional position of the patient's teeth and head during imaging. The device is used to selectively eliminate radiographic scatter in the perfected computer model of the patient's jaws. Digital recording of jaw motion with ultrasound provides a simple and precise method of recording and reproducing jaw motion in the virtual model. This computer model eliminates the need of using a face bow or dental articulator for the diagnosis and treatment of aesthetic and functional dental problems. It also opens the way to direct digital manufacturing of complex dental devices.
Steve Schmitt, Dental Implant Technologies

Application of 3D Scanning for Breast Surgery and Reconstruction
Recent work provides data to support the use of 3D imaging as a valuable tool in aesthetic and reconstructive breast surgery. A system has been developed for creating 3D breast models that provides clinical data that can help guide surgical management. Three-dimensional imaging may be applied to various plastic surgery procedures including breast reconstruction with implant/tissue expanders, local flap reconstruction, free-flap reconstruction, breast augmentation, and breast reduction surgery. The approach provides advantages over procedures and are based on two-dimensional photographs and visual size estimates.
Dr. Oren Tepper, New York University

11:00 a.m. - 1:00 p.m.
Lunch on the Show Floor

1:00 p.m. - 3:45 p.m.
3D Scanning and Reverse-Engineering a Crime Scene
A beta version of a software program designed to aid in putting a face on skeletal remains or those unrecognizable is the result of a continuing development with General Electric and the FBI. It requires a CT Scan or a sub millimeter scan of the remains in an stl format. A demo will be given to show the current progress in development of this software, which is free to all law enforcement agencies and crime labs.
Carl Adrian, FBI

Reconstructing George Washington in 3D
In 2004, Mt Vernon commissioned a forensic anthropologist and a computer scientist to lead a project to reconstruct George Washington in 3D at the ages of 19, 45 and 57 based on images and other 3D evidence. The challenges of scanning and reverse engineering/aging of a figure and the project process will be presented.
Anshuman Razdan, Arizona State University
