Smart Fusion NextGen

A New Milestone in Intelligent Process Control for Metal AM

FEBRUARY 02, 2026 | Reading time: 3 min

 

Smart Fusion is already well established in the metal AM market as a proven technology that stabilizes heat input, reduces support structures, and enables more reliable builds. Manufacturers across industries rely on Smart Fusion to manage thermal variations during the LPBF process and ensure stable, high‑quality production outcomes. By automatically adjusting laser power in real time, Smart Fusion transformed additive manufacturing from a static process into an adaptive one.

With the latest EOS Software Release V24, we are taking this innovation one decisive step further.

Introducing Smart Fusion NextGen

Smart Fusion NextGen extends intelligent heat management and laser power control to an even broader range of applications and materials. It delivers enhanced buildability across all released materials (In718, Ti64, and AlSi10Mg), and now also EOS MaragingSteel: MS1 and EOS StainlessSteel: 316L. This marks the broadest material coverage Smart Fusion has ever offered.

 

What’s New: Higher Quality, Better Accuracy, More Confidence
Building on years of process expertise and customer feedback, Smart Fusion NextGen introduces three major advancements:

  1. Improved Downskin Surface Roughness
    An optimized algorithm reduces downskin surface roughness, resulting in smoother, more consistent part surfaces, even in challenging geometries.
  2. Higher Downskin Accuracy
    Refined, localized heat control leads to noticeably improved dimensional accuracy on downskin and overhanging features by reducing overheating distortion.
  3. Reduces Pores
    In overhangs below 15°, Smart Fusion NextGen significantly minimizes pores in downskin.  It has been documented that SF1 led to a “false ceiling” in some instances. Now with SF NG extreme low angles are built smoother and without these large pores.
Improvement Through Software Update V24

The Next Chapter in Smart Fusion

For the first time, Smart Fusion supports not only high‑demand aerospace‑grade materials, but also widely used industrial alloys such as MS1 and 316L. This makes advanced, in‑situ thermal control accessible to an even wider set of applications and industries.

Smart Fusion NextGen delivers reliable, repeatable, and high‑quality results across more geometries, materials, and use cases than ever before representing another major milestone on the path toward fully autonomous, self‑optimizing metal 3D printing.

 

Available Now: Smart Fusion NextGen is included in the new EOS Software Release V24 and is available immediately to all customers with compatible EOS systems.
