INTERNAL R&D DEPT.

PROGOL3D® internal R&D lab offers a sophisticated service in terms of product innovation, constantly searching for the most suitable solutions according to the market's needs.

MORPHOLOGICAL POWDER ANALYSIS
The powder morphology is analysed at a micron-level thanks to Scanning Electron Microscope (SEM), combined to Energy Dispersive X-Ray device (EDX) for a complete quantitative-qualitative analysis and purity assessment.
GRANULOMETRIC ANALYSIS
The granulometer assesses the dimensional properties of the particles. The size of each grain is compared to the analysis sample and must fall within the given tolerance range.
FINENESS TEST
The spectrophotometric analysis reveals the elemental composition of each sample and, in so doing, allows the accurate certification of the alloy fineness.
FIRE ASSAY
The fire assay method is considered compliant with the standard to ensure the most accurate fineness determination of jewels.
SURFACE ROUGHNESS ANALYSIS
Measuring and assessing the surface micro-irregularities of the printed pieces, at a X thousandth of a micron accuracy level.
