Powder Analysis
Before any production build, each batch of new powder is analyzed on-site by Sintavia. This is a critical step for success.
Size distribution, chemical composition, and powder porosity are all important factors in ensuring a successful and optimal outcome.
Before a run, powder it is tested to ASTM and company specifications.
Sintavia uses powder from approved suppliers and that is tested for conformance upon arrival.
The company is not aligned with any one powder source, giving Sintavia’s customers the flexibility to choose their preferred powder. Review the Materials Guide for more information about metal powders.

Sintavia Metallurgical Services for AM Include:
Mechanical Testing
As part of its material characterization lab, Sintavia offers comprehensive mechanical testing capabilities using some of the most advanced equipment available.
Sintavia’s mechanical testing laboratory is ISO 17025/ANAB accredited and performs the following tests:
Creep/Stress Rupture
Tensile Testing
Mechanical Testing of AM Builds
Mechanical Testing provides validation and confirmation to additive and traditional manufacturing processes as they relate to forces applied in static or dynamic applications.
A mechanical test can validate newly developed material and process technologies as well as provide a method of controlling quality.
Typical mechanical testing properties include elasticity, tensile strength, elongation, hardness, fracture toughness, impact resistance, creep, stress rupture and the substantiation of fatigue limits.
