What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.

About this product
The Passivation module designed for the 3D Lab is an automated system that is used to passivate powder materials by slowly adding oxygen to the powder container until it becomes resistant to further reaction with the environment. The passivation process is designed to be controllable and can take between 1-2 hours depending on the type of material being used. The passivation module is designed for use with 3D Lab powder containers, and the automated system ensures that the passivation process is performed safely with no risk of ignition or explosion.
ATO Passivation Module Features
No risk of ignition or explosion
Once the passivation process is complete, the powder container can be safely opened without risk of ignition or explosion. The passivated powder material can then be used in a variety of applications, with the oxide layer helping to maintain the quality and performance of the material over time.
OXYGEN AMOUNT CONTROL
The passivation process itself involves introducing a controlled amount of oxygen into the powder container, which gradually reacts with the material to create a thin, protective oxide layer on the surface of the powder particles. This oxide layer helps prevent corrosion and other forms of degradation, improving the overall stability and performance of the material.
safe and comfortable passivation
The Passivation Module provides a safe and controllable method for passivating powder materials, improving the reliability and quality of the resulting powder.

★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
