Our team of engineers, model makers and 3D printing professionals offers three decades of 3D printing, engineering and manufacturing experience.

3D Printing Technology

We operate 24/7 from our 4,500 square feet Innovation Center with more than a dozen 3D printers.

Professional Printer Sales

As a leading Markforged and HP value-added reseller, InterPRO helps companies reinvent their in-house engineering and manufacturing processes.

Innovation Center

Located in Deep River, Connecticut our modern and advanced additive manufacturing facility is focused on delivering value through strong collaboration, and a hands-on customer experience. Our in-house capabilities include:

  • 3D printing (SLA, MarkForged, SLS, FDM, Polyjet, DMLS)
  • Low-volume production with urethane and silicone casting
  • Prototype injection molding
  • Custom painted appearance models
  • CNC
  • Reverse engineering

See the technology in action!

Our Innovation Center is now open to visitors. Take advantage of this great opportunity to expand your knowledge of 3D printing technologies and get a better understanding of how they can transform the way you design and manufacture products.

Technology Spotlight

Multi Jet Fusion

Reinvent how you prototype and produce functional parts — Multi Jet Fusion (MJF) technology builds complex and highly detailed thermoplastic parts up to 10 times faster than SLS (Selective Laser Sintering). MJF is ideal for fast production of high quantities of parts with outstanding economy.


MarkForged is overturning not only the 3D printing industry but also traditional manufacturing methods. Users can 3D print parts that are much stronger, stiffer and more impact resistant than parts from any other 3D printer, giving companies unprecedented cost, time and efficiency savings.


Stereolithography (SLA) is the first choice for producing complex geometries with excellent accuracy and great surface finish. InterPRO operates nine SLA high resolution and large frame SLA systems in-house including the UnionTech RSPro 800 with a build volume of 31.5 x 31.5 x 21.7 inches capable of producing parts up to 40 inches long with 0.002 in (0.05 mm) layer thickness.


From case studies to white papers, you’ll find a wide selection of learning materials that you can leverage to expand your knowledge of HP and Markforged additive manufacturing technologies.
