The Engineering Design and Prototyping Center is an exceptionally qualified technical resource for:

• Concept development
• Project design
Project enhancement
• Advanced prototyping services

The Center offers extensive technical support for industrial R&D as well as university research throughout the state of Iowa.

SEND COMPUTER-AIDED DESIGN FILES

The Engineering Design and Prototyping Center has the capability to convert most CAD files into formats that will drive its CNC machines and equipment. If you would like to have your CAD projects machined or modeled, save your files in either an "IGES" or "DWG" format machining, or save your 3-D solid files in an "STL" format for modeling. Attach the formatted files to an e-mail message send them to the above email address or provide a web site address where the files can be accessed. Security and confidentiality will be maintained at all times.

FULL SERVICE PROJECT DEVELOPMENT

In addition to mechanical consultation, design, modeling, and fabrication, the Engineering Design and Prototyping Center works jointly with Computer Services and Support (College of Engineering), Engineering Electronics Shop, various University and commercial service centers, and qualified specialty vendors to produce custom apparatus with programmable automation and data collection capability.

Technology is our business, and to insure accuracy, uniformity, reliability, and value, we use the most advanced equipment and machining techniques available. Included in the full line of tool room equipment used at the Engineering Design and Prototyping Center are CNC Milling Machines, a Rapid Prototyping Machine, an Electrical Discharge Machine, precision Engine Lathes, Computers, and a popular selection of CAD/CAM Software.

RAPID PROTOTYPING ON SITE

Rapid Prototyping provides those in R&D, engineering, and medicine throughout the state with a means of inexpensively modeling the objects of their choice. Properly formatted digital files extracted from CAD 3-D solid drawings, CT scans, and MR images are used to drive the building processes of the Center's Fused Deposition Modeling machine (FDM). The resulting ABS models are accurately defined, quickly, fabricated, and universally practical.

STAFF EXPERIENCE ON SITE

Each full-time staff member of the Engineering Design and Prototype Center is a journey level toolmaker with extensive and varied experience. The challenges of designing, developing, and crafting everything from the one-piece "make it while you wait" project to the complex multi-faceted project requiring hundreds of hours to create are routinely met by the Center's staff. In a continuing effort to provide the best technological services possible, the Center and its staff members aggressively pursue improved design, fabrication, and rapid prototyping technologies.
