Additive Manufacturing: Quality Control & Material Validation

Additive Manufacturing (3D Printing) is one of the most transformative innovations in the modern production landscape. However, the integrity and reliability of printed components depend strictly on the characteristics of the metal or polymer powders, the precision of process parameters, and the rigorous inspection of the finished part.

In view of the upcoming opening of our office in Dubai, which will serve as a direct interface for the UAE market, we offer our support to companies and research centers in the United Arab Emirates (UAE) operating in the field of metal and polymer 3D printing, providing a comprehensive range of chemical, physical, and metallographic analyses. Leveraging the advanced diagnostic capabilities of our laboratory in Italy, we ensure that both raw materials (powders) and additive manufactured products meet the highest industrial standards of performance and safety.

Powder Analysis for Additive Manufacturing

Consistency and quality of the raw material are the essential foundations for ensuring reliable and repeatable 3D-printed components. Our laboratories perform all necessary verifications for the qualification, validation, and continuous monitoring of metal and polymer powders. With the advanced analytical depth of our Italian facility, we provide a complete diagnostic framework to certify that your starting materials meet the highest industrial performance standards.

Chemical Analysis

  • Determination of Carbon, Sulfur, Oxygen, Nitrogen, and Hydrogen using specialized infrared and thermal conductivity analyzers. Performed in accordance with accredited standards ASTM 1019 for the determination of C/S/O/N in steels, ASTM E1447 for determining H in titanium, ASTM E1409-13 for determining O/N in titanium, and ISO 13093 for determining C in titanium, this analysis is vital for detecting oxidation or contamination that can cause structural embrittlement.
  • Using ICP–OES spectrometry according to ASTM E1479 and ASTM E2371, it is possible to verify the exact concentration of alloying elements. This ensures the powder’s chemical profile is consistent, guaranteeing repeatable mechanical properties and metallurgical stability.

Particle Size Distribution

Measurement of particle size distribution using calibrated mechanical sieves in compliance with ASTM B214-22. This method identifies the percentage of particles in each fraction, allowing us to detect batch variations or powder degradation phenomena.

Hall Flow and Apparent Density

Evaluation of flowability and packing density of the powder according to ASTM B212-21 and ASTM B329-24. Understanding these parameters is essential for ensuring a uniform layer deposition during the 3D printing process and avoiding internal porosity.

Morphological Analysis (SEM)

Using Scanning Electron Microscopy (SEM), it is possible to characterize particle shape, sphericity, and the presence of satellites, oxides, or contaminants. High-resolution imaging provides a deep understanding of powder quality before it enters the production line.

These comprehensive analyses allow for the monitoring of material stability, the identification of hidden contaminants, and the assurance of powder quality before it enters the additive manufacturing process. This preventive approach is essential to minimize production waste and guarantee the structural integrity of the final 3D-printed component.

Testing on 3D Printed Components

Beyond powder characterization, APM provides a comprehensive suite of mechanical and metallographic tests on components manufactured using additive technologies. These analyses are essential for validating the printing process and ensuring the structural integrity of the final part:

Mechanical Characterization

Tensile testing on specimens or sections extracted from the 3D-printed component. Verification of yield strength, ultimate tensile strength, and elongation, accounting for process anisotropy.

Microstructural Analysis

Preparation of samples for metallographic analysis, optical microscopy, and SEM for the evaluation of grain structure, porosity levels, and internal defects, verification of adhesion between layers.

Hardness & Thermal Validation

Hardness testing (Vickers/Rockwell) to evaluate the efficiency of post-processing heat treatments (Stress Relieving, HIP). Assessment of surface hardening and metallurgical stability.

These tests allow the printing process to be validated, materials and production parameters to be compared, and compliance with the required technical specifications to be ensured.
