Dyndrite, a U.S.-based 3D printing software developer, has announced the integration of PermiAM—the controlled permeability process by Elementum 3D, a U.S. provider of 3D printing metal alloy—into its Dyndrite LPBF Pro software. This collaboration enables Laser Powder Bed Fusion (LPBF) engineers to manufacture metal components with both porous and solid sections within a single build, enhancing coolant flow, reducing assembly complexity, and improving structural reliability.
“Integrating PermiAM into Dyndrite LPBF Pro is a significant step forward in making advanced permeability-controlled metal AM at scale a reality,” said Dr. Jacob Nuechterlein, President & Founder of Elementum 3D. “This collaboration with Dyndrite will help push the boundaries of what’s possible with metal 3D printing, bringing next-generation materials and manufacturing techniques to real-world applications.”
Advancing Metal 3D Printing with PermiAM Technology
PermiAM is a patent-pending additive manufacturing (AM) technology initially developed by Masten Space Systems (now part of Astrobotic) and Elementum 3D. The technology allows for the creation of metal components that smoothly incorporate controlled permeability regions alongside fully dense structures. Dyndrite explained that by managing part porosity during production, engineers can design tailored fluid control systems with optimized performance for demanding applications, while also streamlining the design process and reducing costs.
“By enabling and scaling Elementum 3D’s PermiAM technology into Dyndrite LPBF Pro, we’re giving engineers and manufacturers unprecedented control over material properties, enabling production of concepts once thought impossible,” said Harshil Goel, Founder and CEO of Dyndrite.
Although initially tested in aerospace applications, such as hot fire trials for 3D-printed fuel injectors, PermiAM holds broad potential across industries requiring exacting fluid control. Its applications extend to fields such as commercial jet engines, automotive fuel injection systems, and advanced data center cooling solutions.
Boosting PermiAM Adoption Across Industries
To support wider industry adoption, PermiAM will be offered as a plug-in for Dyndrite LPBF Pro, allowing users to apply PermiAM to parts with greater complexity, including intricate geometries, curved 3D paths, amorphous shapes, and functionally graded transitions between porous and solid materials. The PermiAM plug-in for Dyndrite LPBF Pro will be made available via Elementum 3D.
Dyndrite also announced that Elementum 3D has secured an AFWERX contract to support the commercialization of PermiAM® for defense applications and is actively seeking industry partners, especially in the space and defense sectors, to drive further development and implementation.
Dyndrite LPBF Pro: Advancing Metal Additive Manufacturing
In 2024, Dyndrite introduced an enhanced version of its LPBF Pro software, designed specifically for LPBF-based metal additive manufacturing. Utilizing GPU acceleration, the software enhances computational performance and is compatible with leading LPBF machine manufacturers, including Aconity3D, EOS, Nikon SLM Solutions, Renishaw, and Xact Metal.
In another effort to improve the LPBF process, Belgian 3D printing software and services provider Materialise partnered with ArcelorMittal Powders, a division of global steel manufacturer ArcelorMittal, in 2024. This collaboration aims to enhance the speed, quality, and cost-efficiency of LPBF 3D printing while optimizing metal 3D printing strategies for better performance and efficiency.
