Rosotics launches large-scale induction metal AM machine, partners with Siemens
July 29, 2024

Rosotics, Mesa, Arizona, USA, has launched its large-scale induction heating Additive Manufacturing machine, called Halo. The company has also partnered with Siemens in order to develop – and bring to production – a super heavyweight Additive Manufacturing machine geared toward naval applications. The machine will be supported by Siemens’ Sinumerik One CNCs system.
Rosotics’ Halo is a large-format metal Additive Manufacturing machine targeting aerospace, naval, and defence applications. The Halo employs a multi-phase electromagnetic process in place of conventional AM energy sources such as lasers. The company’s HalOs software controls three electromagnetic induction-based ‘Mjolnir’ Additive Manufacturing heads to produce near-net shape parts.
It is stated that the Mjolnir head assemblies have the ability to pre-heat, fuse materials at high feed rates, and conduct prolonged thermal cycles, producing net-shape parts with smooth surfaces. Each Halo machine features three Mjolnir heads mounted on freestanding towers with multi-axis gimbals, all developed in-house by Rosotics.
Rosotics notes several benefits of this new technology, such as reduced power and infrastructure requirements. The Halo also features integrated post-processing and claims improved operational safety.
The machine is designed for heavy industrial production applications and for repairing and maintaining existing structures. Halo’s ‘Reach’ configuration offers a 9 m build envelope. It is also advertised as supporting complex geometries and post-build inspection and servicing tasks.
As of launch, the Halo offers compatibility with a range of metals and alloys, including those frequently used in aerospace and naval applications. Additionally, Rosotics has qualified material performance in aluminium, meeting tensile and yield strength standards. A controlled atmosphere System Enclosure that offers an inert environment for more sensitive materials, like titanium, can also be added to the Halo system. The machines are assembled at Falcon Field Airport in Mesa, Arizona.
Working with Siemens, Rosotics intends to directly produce a new private-sector vessel and an autonomous underwater vehicle (AUV) for naval use. A 25 m super-heavyweight platform will carry the Mjolnir build architecture, which is currently used on Rosotics’ Halo commercial Additive Manufacturing machines, and will be located near San Diego, California.
“Siemens is excited to join forces with Rosotics in this groundbreaking endeavour,” the company stated. “The integration of Sinumerik One with Rosotics’ advanced manufacturing system for this effort will create a platform of immense significance, capable of addressing the most complex production challenges in the naval industry.”
“We are thrilled to work with Siemens on creating this remarkable architecture; their shared commitments to sustainable manufacturing and deep capabilities in complex kinematics will be paramount drivers of this endeavour,” added Rosotics’ founder Christian LaRosa. “Their demonstrated heritage in renewable energy speaks volumes to us and we do value it. We each carry optimism.”
