Making the unmakeable: How metal AM is bringing the aerospike rocket engine to life

The history book of engineering is filled with concepts that failed to achieve success because they were ahead of their time. This was almost the case for the aerospike rocket engine, recognised in the 1950s as a strong concept and tested by NASA in the 1980s and 1990s, but found to demand too much of the manufacturing and materials technology available at the time.

Metal AM magazine spoke with Pangea Aerospace and Aenium Engineering about reinventing the aerospike for the 21st century, and how Additive Manufacturing allowed them to ‘make the unmakeable’ – pushing their expertise in AM, materials science and Design for AM to its limits in the process.

Seurat Technologies: Evolving AM to finally out-compete conventional manufacturing

Every so often, something comes along that gets the whole Additive Manufacturing industry talking.

Over the past two years, few companies have generated as much intrigue as Seurat Technologies, the Lawrence Livermore National Laboratory spin-out named for the French pointillist, bringing with it a technology roadmap that promises to evolve metal AM to the crucial point of out-competing conventional manufacturing methods.

In this Metal AM exclusive, James DeMuth, Seurat CEO, offers the deepest look yet into the technology behind his company’s promise.
