Our processes

Metal additive manufacturing and its unique use, combined with surface engineering.

At AM3L, we push back the frontiers of manufacturing with cutting-edge technologies. Our expertise focuses on two key elements: metal additive manufacturing and surface treatments.

Metal additive manufacturing

Additive manufacturing is at the heart of our approach, with the Laser Powder Bed Fusion (LPBF) process.

This technology enables us to create complex metal parts by successive addition of material, layer by layer, from a 3D digital file. The process involves spreading thin layers of metal powder on top of each other, with selective consolidation of the material by one or multiple lasers between each layer.

This process offers numerous advantages:

  • Customization: it enables the creation of tailored components, adapted to your specific needs with easy integration into existing systems.
  • Complex geometries: the design freedom offered by this technology extends the field of possibilities. It allows us to produce lightweight, architectured parts, with a total control of the material porosity.
  • Performance: our products feature micrometric geometric precision, combined with mechanical properties and corrosion resistance that are equal to or superior to those of traditionally manufactured components.
  • Circular economy: we manufacture durable parts with minimal material loss. Any powder not melted during the process is reused for future fabrication.
  • Accelerated industrialization: this agile process in terms of development and customization enables us to qualify and produce parts with extremely short lead times.

These advantages position the L-PBF process as a particularly powerful and versatile additive manufacturing method for the development and production of customized metamaterials.

Innovative use of metal 3D printing

In addition to computer-aided design (CAD) and topology optimization to create architectured materials such as lattice structures, AM3L exploits the LPBF process in unexplored parametric domains to control the architecture and porosity of its products.

These multi-scale architectures provide total control over the materials performance, in fields as varied as shock absorption, thermal properties and industrial filtration.

Surface engineering

In addition to customized 3D designs, AM3L products can be functionalized by surface treatment.

Different surface engineering technologies are used, depending on requirements and materials. Thin-film deposits or coatings are applied to the 3D-printed materials, using gaseous or physical precursors.

These treatments improve the surface properties of the parts, as well as adding specific functional properties.
