What your process engineer actually checks
Reactive powder, handled safely
Freshly atomized titanium, aluminium and other reactive powders are pyrophoric. The Passivation Module builds a controlled oxide layer before the container is opened, so your team handles the powder without ignition or explosion risk.
Controlled, not improvised
Passivation by slow, metered oxygen dosing gives a repeatable oxide layer that protects the powder in storage — not a hand-managed step that varies operator to operator. Typically 1–2 hours, hands-off.

About this product
ATO Passivation Module is an automated safety system that passivates reactive metal powder — slowly dosing a controlled amount of oxygen to build a thin protective oxide layer, so a freshly atomized powder container can be opened without any risk of ignition or explosion.
Why reactive-powder producers passivate before opening
Freshly atomized titanium, aluminium and magnesium powders are pyrophoric. The module turns a dangerous step into a controlled, repeatable process.
Controlled oxygen dosing
The module introduces a precisely metered amount of oxygen that reacts gradually with the powder surface, building a uniform protective oxide layer instead of an uncontrolled reaction.
No ignition or explosion risk
Passivation completes before the container is ever opened, so operators handle the powder safely — no flash, no explosion risk, no improvised precautions.
Automated 1–2 h cycle
A hands-off automated cycle, typically 1–2 hours depending on the alloy. Set it and the module manages the dosing safely to completion.
Works with ATO containers
Designed to connect directly to ATO 3D Lab powder containers, so passivation happens in the same vessel the powder was collected in — no risky transfers.
How passivation runs
A controlled, repeatable oxide-layer build — the opposite of opening a sealed container and hoping.
Step 01
Connect the container
After atomization, the sealed ATO powder container connects to the passivation module under inert conditions.
Step 02
Dose oxygen, build oxide
The module slowly introduces controlled oxygen; a thin protective oxide layer forms on each particle surface over 1–2 hours.
Step 03
Open safely
Once passivation is complete the container opens with no ignition or explosion risk; the oxide layer keeps the powder stable in storage.

What does the ATO Passivation Module do?
The ATO Passivation Module passivates reactive metal powder by slowly dosing a controlled amount of oxygen into the sealed powder container. The oxygen reacts gradually with the particle surfaces to build a thin, protective oxide layer. This makes freshly atomized reactive powder safe to handle — the container can be opened afterwards with no risk of ignition or explosion, and the oxide layer keeps the powder stable in storage.
Why does reactive metal powder need passivation?
Freshly atomized reactive metals such as titanium, aluminium and magnesium are pyrophoric — their clean, high-surface-area particles can ignite on contact with air. Passivation builds a controlled oxide layer first, so the powder no longer reacts violently with the environment. Without it, opening a container of fresh reactive powder is a serious ignition and explosion hazard.
How long does passivation take?
A passivation cycle typically takes 1 to 2 hours, depending on the alloy and the amount of powder. The ATO Passivation Module runs the cycle automatically and hands-off — an operator sets it and the module manages the controlled oxygen dosing safely through to completion.
Is the passivation process itself safe?
Yes — that is its purpose. The module introduces oxygen slowly and under control rather than exposing the powder to air all at once, which eliminates the ignition and explosion risk of manual handling. The automated system manages dosing throughout the cycle, and only once passivation is complete is the container opened. Additive Plus includes installation and operator training.
Which powders and containers is it compatible with?
The ATO Passivation Module is designed for reactive metal powders — titanium, aluminium, magnesium and similar reactive alloys — and connects directly to ATO 3D Lab powder containers, so passivation happens in the same vessel the powder was collected in. Additive Plus configures it around your specific alloys and atomizer setup.
What is the lead time and how is the passivation module priced?
The ATO Passivation Module is configured to order and priced per configuration, so pricing and lead time depend on your reactive alloys, container and atomizer setup. Request a quote and an Additive Plus applications engineer will confirm the right configuration, current lead time and a full quotation — usually with a sub-4h first response.
