HRE Wheels and GE Additive unveiled the first titanium wheel created using electron-beam melting (EBM) technology, a type of 3D printing. With a traditional aluminum Monoblok wheel, 80% of material is removed from a 100-pound forged block of aluminum to create the final product. With additive manufacturing, only 5% of the material is removed and recycled, making the process far more efficient. Titanium also has a much higher specific strength than aluminum and is corrosion resistant, allowing it to be extremely lightweight. Known as HRE3D+, this new prototype wheel shows how advanced materials like titanium can be harnessed to create complex designs. The wheel was produced on two Arcam EBM machines in five separate sections then combined using a custom center section and titanium fasteners.
Germany’s SMS group won the German Design Award in the “Industry” category for an additively manufactured spray head used to cool dies in the forging industry. The award recognizes innovative products and projects and the companies or individuals who have fabricated and designed them. In this case, it was not only the spray-head component that was noteworthy, but also that additive-manufacturing (AM) techniques were used to produce the part.
Metal 3D printing, or additive manufacturing (AM), is an advanced manufacturing method that opens up new possibilities for designing objects with optimized geometries and minimized weight using far less material and energy – important drivers for a future sustainable, energy-efficient industrial base.
Arconic announced a multi-year cooperative research agreement with Airbus to advance metal 3D printing for aircraft manufacturing. The companies will develop customized processes and parameters to produce and qualify large, structural 3D-printed components, such as pylon spars and rib structures, up to approximately 3 feet in length. The deal combines Arconic’s expertise in metal additive manufacturing and metallurgy with Airbus’ design and qualification capabilities.
Additive-manufacturing (AM) technologies have drawn a lot of attention and investment from the manufacturing community in recent years. This article presents an overview of AM processes, including their economic and operational advantages and constraints.
