New dual-use capability enhances thermal protection for hypersonics, rockets, data centers, and propulsion.
Dyndrite announced that Elementum3D has selected its Dyndrite LPBF Pro software to integrate the PermiAM controlled permeability process. This integration allows Laser Powder Bed Fusion (LPBF) engineers to produce parts with both porous and solid sections in a single build, supporting coolant flow while reducing the need for assembly and potential failure points.
PermiAM is a patent-pending additive manufacturing (AM) technology developed collaboratively by Masten Space Systems (now Astrobotic) and Elementum 3D. The technique enables the creation of metal components that integrate regions of controlled permeability with fully dense structures within a single part. This capability is particularly advantageous in hypersonic applications and rocket engine injectors. Controlling part porosity during the production process allows engineers to construct customized fluid control systems with optimized performance for extreme applications, while simplifying design steps and cutting costs. The application of PermiAM was tested through hot fire trials of a 3D-printed fuel injector, demonstrating its use in aerospace manufacturing.
Beyond aerospace, PermiAM may be useful in industries requiring precise fluid control, including commercial jet engines, automotive fuel injection systems, and data center cooling. By allowing the fabrication of parts with adjustable permeability, this technology helps optimize performance and efficiency in engineering applications.
PermiAM will be integrated into Dyndrite LPBF Pro as a plug-in, enabling engineers to apply it to parts with curved 3D paths, complex geometries, and gradual transitions between porous and solid materials. The companies will also partner in the testing and validating of physical printed demonstrators.
The PermiAM plug-in for Dyndrite LPBF Pro will be made available through Elementum3D.
Elementum 3D has received an AFWERK contract to commercialize the PermiAM solution for defense applications.
