About

We offer integrated expertise in powder technology and additive manufacturing, with the posiibility of the reuse and qualification of materials for advanced part production.

Core Competencies:

  • Advanced powder characterization
    – Particle size distribution (laser diffraction)
    – Morphology (SEM), flowability, bulk density
    – Chemical purity (O, N, H, C, S)
    – Thermal behavior (DSC, TGA), sintering kinetics (dilatometry)

  • Powder processing & feedstock preparation
    – Mechanical milling, mixing, granulation
    – Feedstock formulation for PIM (MIM/CIM) and binder-based AM
    – Qualification of recycled powders or industrial by-products

  • Additive manufacturing prototyping
    – Design and fabrication of complex geometries using SLM, SLS, Binder Jetting
    – Adaptation of process parameters for reused/reconditioned materials

  • Post-treatment and material characterization
    Hot Isostatic Pressing (HIP) to improve density, eliminate internal porosity, and enhance the mechanical properties and reliability of sintered or additively manufactured parts.

    -Debinding, sintering, thermal treatments under controlled atmospheres
    – Microstructure analysis SEM/EBSD mechanical testing
    – Evaluation of performance after reuse or repair

Field

  • (Advanced) Materials and additive manufacturing
  • Industry 4.0 technologies
