PA-300 LPBF Metal Printer Processes Magnesium and Reactive Alloys
The PA-300 from Precision Additive, a new US-based additive manufacturing company, is a laser powder bed fusion (LPBF) metal additive manufacturing system designed to produce qualification-ready components for defense, aerospace, energy, and medical applications. It is built around two proprietary technologies: Selective Stepped Laser Melting (SSLM) and the Precision Additive Quality (PAQ) Framework.
SSLM replaces conventional Gaussian laser scan strategies, which can produce unstable melt pools, material vaporization, and porosity. The approach stabilizes the melt pool and reduces spatter, enabling consistent mechanical properties across builds. The system also includes a sealed chamber with oxidation control near zero and a separate reactive gas stream—features that allow it to process magnesium, a highly reactive material in powdered form that conventional LPBF systems have not reliably handled at production scale.
The PAQ Framework integrates real-time sensing, process control, and part-specific digital twins. The system continuously monitors each build and automatically corrects deviations, with parameters adjusting on the fly based on sensor feedback.
The PA-300 also incorporates hybrid functionality, allowing machining of internal features within the LPBF process to address surface roughness and defect propagation.
The PA-300 is configured to print magnesium, aluminum, titanium, Inconel, tungsten, molybdenum, and cobalt. Magnesium support is a primary differentiator: the material is approximately 40% lighter than aluminum and offers vibration-dampening properties relevant to aerospace and defense platforms, but its reactivity has historically limited industrial AM adoption.
