Additive Manufacturing (AM) and 3D Printing
Additive manufacturing (AM) and 3D printing encompass a range of processes used to create parts from CAD files by gradually adding material. Additive processes bring a number of benefits that subtractive manufacturing (machining and other processes that remove material) and other common manufacturing processes do not. These include virtual total freedom in terms of design, integrated functions, customization, fast turnaround, and lower mass.
Additive manufacturing has exploded over the past decade, (Wholers Report 2019 -

Liten's know-how covers the entire 3D printing value chain
In 2014, Liten began to expand the scope of its powder metallurgy research by investing in 3D printing using metals. From the very early days of Liten's foray into metal 3D printing, the institute formed partnerships with machine manufacturers to support the emergence of a metal 3D printing industry.
Specifically, Liten's research focuses on:
With additive manufacturing, parts with complex designs can be made in a single step. CEA Liten, a CEA Tech institute, recently used the technique to prototype a heat exchanger-reactor that could lead to more efficient production of synthetic fuels using a process called CO2 hydrogenation.
A power transformer with satisfactory thermal performance was produced using powder injection molding (PIM) and a printed-circuit-type industrial assembly. This advance will pave the way to smaller power supply components suitable for a variety of mobile devices.
