Over 16,000 Square Feet of Combined In-House Prototype Shop Space

Our shop is built to be highly configurable so we can adapt our space to fit your needs. Take advantage of our rapid prototyping space to crank out 3D models for more iterations in a shorter period of time. Need a show-quality piece? Our large paint booths and talented specialists are the formula for world-class finishes.
For highly confidential projects, we have created our own “Area 51” space to keep your work top secret during testing and prototype builds.

Specialized Metal Fabrication Equipment To Handle Every Application

Many products rely on off-the-shelf parts. However, developing custom components guarantees that your parts are made specifically for your application.  At i3, we use a variety of tools to produce the specialized metal components  for your product. Our metal fabrication lineup includes CNC machines, a press brake, laser cutting machine, water-jetting machine and a welding table.

Welding capabilities include MIG and flux-cored welding, TIG and stick welding for aluminum and stainless steel along with complex frame weldments and general fabrication services.

Our CNC Machining Services are Always Expanding

To better serve your needs, i3 now boasts a total of 6 CNC machines including several 3-axis and a 4-axis Fadal Vertical Machining Centers, a Doosan CNC Lathe along with our in-house team of highly skilled CNC prototype specialists at our facility in Sun Prairie.  

CNC machining provides you with fast turnaround, superior quality, and high precision parts in a variety of materials with comparable costs to other prototyping processes. Parts are machined from solid stock, eliminating weakness that may be associated with 3D printed parts. Below is a selection of commonly used materials in our CNC machining applications.

Plastics Metals Foams
Other rigid foams
Stainless Steel

We also offer post-processing services including bead blasting, tumbling, anodizing, painting, powder coating, etc.

We have the tools and talent to help your product take shape
