🟦 Granutools at METAL AMS 2026 – Advancing Metal AM Through High‑Precision Powder Characterization

Granutools is pleased to announce its participation in METAL AMS 2026, the leading French scientific event entirely dedicated to Metal Additive Manufacturing (Metal AM). The conference will take place on March 25–26, 2026 at CETIM in Senlis, gathering international experts, researchers, and industry professionals to address every step of the metal AM value chain—from powder design to process monitoring and final part qualification.

Recognized for its strong focus on materials science, simulation, powder quality, and AM component qualification, METAL AMS features more than 70 speakers, three parallel rooms, and a vibrant exhibition area hosting key AM technology providers. This third edition highlights the increasing need for reliable qualification methods in a rapidly maturing industry. 

🔬 The Central Role of Powder Behavior in Metal AM

In Metal AM processes such as SLM, EBM, DED, and sintering-based technologies, powder behavior plays a central role in determining:

• Layer uniformity
• Melt‑pool stability
• Part porosity and density
• Surface quality
• Repeatability and productivity

Traditional standards (e.g. ISO/ASTM 52907) often fall short of capturing real in‑process conditions, especially as powders become finer and more cohesive. These sensitivities are influenced by:

• Particle morphology & size distribution
• Surface chemistry
• Environmental humidity
• Cohesive and adhesive forces
• Powder ageing across multiple reuse cycles

To address these challenges, Granutools offers GranuDrum, GranuPack, and GranuCharge, automated, repeatable instruments that deliver process‑relevant insights, helping AM experts characterize powders far beyond the limits of traditional laboratory methods.

🟦 Granutools Scientific Contributions at METAL AMS 2026

Presentation by Dr. Aurélien Neveu

“15 The Link Between Powder Cohesiveness and Spreadability Evaluated Through Multi‑Layer Analysis”

Date: March 25, 2026
Time: 5:20 PM – 5:40 PM
Room: Room 8
Session Subject: 15 The link between powder cohesiveness and spreadability evaluated through multi-layer analysis

Dr. Aurélien Neveu, Head of Laboratory & Applications at Granutools, will present groundbreaking work on predicting powder spreadability, a decisive factor for layer quality in metal powder‑bed fusion.

According to Granutools’ official communication, Aurélien’s research demonstrates how the Cohesive Index, measured with the GranuDrum, provides a reliable and cost‑effective metric for estimating spreadability, strongly correlated with multi‑layer performance in real SLM conditions. 

His contribution will detail:

• How cohesive forces drive multi‑layer defects
• Why single‑layer tests are often insufficient
• How multi‑layer analysis reveals deeper powder behavior
• Correlations between Cohesive Index and spreadability in SLM
• Implications for powder selection, recoater strategy, and process optimization

This methodology helps AM engineers reduce trial‑and‑error, prevent printing defects, and accelerate powder qualification.
