Our Expertise
Penn United Additive is a metal powder additive manufacturing parts producer focused on complex, precision metal additive manufacturing part development, qualification, and production. We provide end-to-end manufacturing solutions to our customer-partners by adding value through additive manufacturing and offering the best manufacturing method for their most challenging applications.
By combining our knowledge of metal additive manufacturing with decades of experience in subtractive machining and grinding, we apply the best aspects of both AM and conventional manufacturing to help our customer-partners determine the right use and business case for AM parts. As part of our larger Penn United tooling group, Penn United Additive is able to leverage decades of precision tool and die experience to focus on providing additive manufacturing solutions to our current customer-partners throughout the markets we serve.
Since 1971, Penn United has developed strong relationships with many of our customer-partners by providing innovative, value-added manufacturing solutions. Across Penn United’s larger organization, we specialize in high precision metal components, precision tooling, and hard material wear components, affording us the capability to assemble and unite all of this experience to support our AM group. By leveraging our long history of success in precision metals manufacturing with new metal additive manufacturing technology, we have been able to establish ourselves as leaders in the development of AM technology and have propelled to the forefront of the AM industry.
Current AM Machines:
- (5) EOS M290’s
- (1) EOS M400-4
- (1) EOS AMCM M4K-4
Precision Secondary Operations
Developed from the industrial and manufacturing roots of the Pittsburgh region, Penn United is known in the manufacturing industry as a reliable, high precision manufacturer. With competencies in producing, maintaining, and measuring to extremely tight tolerances (less than 0.0001”), Penn United’s legacy of manufacturing capabilities allow us to approach AM part production and qualification from an industrial manufacturing perspective.

Materials
Penn United has optimized and customized unique parameter sets for over 10 different material to be printed at various thickness layers consisting of 20um, 30um, 40um, 50um, 60um, 80um options.
Current developed materials include:
- Inconel 600, 625, 718, 738 & 939
- Haynes 230 & 282
- Stainless Steel 304L, 316L, 17-4 & 15-5
- Maraging C300 (MS1)
- Aluminum 6061 & AlSi10Mg
- Pure Copper, CuNi & C18150
- Titanium Ti6AI4V
- CoCrMo
We have developed and designed builds with multiple parameter sets to run 30um/60um layers often using 30um layers for fine resolution features and 60um layers for larger features. This is useful when transitioning from 30um layers for fine mesh or fin structures in heat exchangers or fine filtering applications to thicker 60um layers for structural or frame features. This process allows us to optimize layer thickness by feature, decrease build time, and reduce cost, while maintaining fine feature control.
