Aluminum 3D printing enhances the advantages of aluminum, such as its lightweight and recyclable nature. Tailored aluminum alloys like Scalmalloy and UniFuse, optimized for additive manufacturing, offer superior strength and properties. They enable the production of complex, thin-walled aluminum parts that outperform traditional manufacturing methods. Industries like aerospace and racing benefit greatly from these advancements in aluminum 3D printing.

Companies like SLM Solutions and Velo3D have developed innovative processes on their 3D printers to maximize the performance of aluminum alloy F357. This alloy, known for its suitability in 3D printing, allows the creation of intricate and challenging structures. Honeywell and SLM Solutions are collaborating to qualify F357 parts for flight applications, while Velo3D and PWR are leveraging F357 to replace casting and produce parts with superior material properties in a shorter timeframe. These developments in 3D printed aluminum are revolutionizing industries, expanding the scope of applications and pushing the boundaries of what can be achieved with this versatile metal.

    How to 3D Print Aluminum

    Metal 3D printing technologies can process aluminum, with variations in speed, size, detail, and feedstock cost.

    1. Laser Powder Bed Fusion (LPBF): Common aluminum 3D printing technology, but not all printers can handle aluminum. Requires optimization of printing parameters for desired material properties.

    2. Electron Beam Melting (EBM): Uses an electron beam instead of a laser. Suitable for titanium-aluminum alloys, not pure aluminum. Coarser microstructure compared to LPBF.

    3. Cold Spray & Wire Arc Additive Manufacturing (WAAM): Rapid production of large aluminum parts, often machined for precision. Cost-effective for unique parts in heavy industry.

    4. Binder Jetting: Fast printing of medium to large volumes of aluminum parts. Requires post-processing.
