What your process engineer actually checks
Oxygen-free sieving you can trust
The ATO Sieve screens and back-fills the ATO container with argon, so reactive powder (Ti, Al, Zr) moves from atomizer to sieve without oxygen pickup. High-frequency ultrasonic vibration clears the mesh instead of letting fines blind it — throughput stays high and the cut stays honest. An optional in-line oxygen sensor lets you watch atmosphere in real time.
An applications engineer on the line
We run the full ATO powder chain in-house through AO Metal / ATO Lab — atomize, sieve, clean, characterize — so this is equipment we operate, not just resell. We match screen mesh to your target PSD and integrate the Sieve with your ATO Lab Plus or ATO Sparq. Sub-24h reply, NDA standard.

About this product
ATO Sieve is an ultrasonic powder sieving station that screens reactive and non-reactive metal AM powder inside an inert argon atmosphere. It uses the same ATO powder container as ATO atomizers, so powder transfers straight from the atomizer to the sieve under an argon shield with no oxygen pickup. High-frequency ultrasonic vibration clears the mesh instead of letting fines blind it, so a lab can classify small batches to a clean, print-ready cut without exposing reactive metal to air.
Why powder producers choose ATO Sieve
Spec-backed reasons a process engineer screens AM powder on this station.
Oxygen-free screening
Sieves under an inert argon atmosphere and back-fills the ATO container with argon — reactive powder never contacts air between atomizer and mesh.
Ultrasonic anti-clog
High-frequency ultrasonic vibration keeps the screen open, so fines don’t blind the mesh and throughput stays high on small batches.
Direct ATO transfer
Uses the same ATO powder container as ATO Lab Plus, ATO Sparq and ATO Noble — powder moves atomizer-to-sieve inside the argon shield.
Optional oxygen sensor
Add an in-line oxygen sensor to watch atmosphere in real time when you classify titanium, aluminium or zirconium powder.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What does the ATO Sieve do in the metal powder workflow?
The ATO Sieve is an ultrasonic sieving station that classifies metal AM powder to a defined particle cut and removes oversized particles and agglomerates before printing. It sits after atomization: powder comes off an ATO atomizer, transfers into the sieve inside the same argon container, and leaves screened and print-ready. Sieving under inert gas keeps reactive powder from picking up oxygen, so the ATO Sieve is the finishing step that turns freshly atomized metal into clean, usable feedstock.
Why sieve metal powder under an inert argon atmosphere?
Reactive metals such as titanium, aluminium and zirconium oxidise quickly in air, and oxygen pickup degrades powder chemistry and print quality. The ATO Sieve screens inside an inert argon atmosphere and back-fills the ATO container with argon, so the powder never contacts air between the atomizer and the mesh. For AM powder that has to meet tight oxygen limits, sieving under argon protects the work already done during atomization instead of undoing it at the last step.
Which sieve mesh sizes are available for the ATO Sieve?
The ATO Sieve accepts various screens, and mesh sizes are selected to your target particle cut rather than fixed at the factory. Because AM processes need different fractions — finer cuts for LPBF, coarser for DED — the screen is matched to the powder and process you run. Tell our applications engineer your target PSD and we confirm the screen configuration for the ATO Sieve before the order is built.
Is the ATO Sieve compatible with my ATO Lab Plus or ATO Sparq atomizer?
Yes. The ATO Sieve uses the same ATO powder container as ATO Lab Plus, ATO Sparq and ATO Noble atomizers, so powder transfers directly from the atomizer into the sieve inside a continuous argon shield. That shared-container design is the point of the system: it keeps the inert atmosphere unbroken from melt to mesh. If you run an ATO atomizer, the ATO Sieve drops into the same workflow with no repackaging or air exposure.
Can the ATO Sieve handle reactive metals like titanium and aluminium?
Yes. The ATO Sieve is designed for both reactive and non-reactive AM metal powders, including titanium, aluminium and zirconium as well as steels, nickel and copper alloys. Reactive powders are exactly why it screens under argon and offers an optional oxygen sensor. For the most sensitive alloys, running the ATO Sieve with the oxygen sensor lets you confirm the atmosphere is clean before and during screening.
What is the oxygen sensor option and do I need it?
The ATO Sieve can be equipped with an in-line oxygen sensor that measures the oxygen level inside the working atmosphere in real time. It is optional: labs classifying non-reactive powder may not need it, but teams working with titanium, aluminium or other oxygen-sensitive alloys use it to verify the argon shield is intact and to document atmosphere quality. Our applications engineer can advise whether the oxygen sensor is worth adding for the metals you run.
How large a powder batch can the ATO Sieve process?
The ATO Sieve is built for the small powder batches typical of lab-scale ATO atomization rather than high-volume industrial classification. It screens the quantity held in the ATO container quickly and efficiently, which suits R&D, alloy qualification and in-house powder production. If your throughput needs grow beyond lab batches, talk to our engineer about matching the ATO Sieve to the right atomizer and workflow.
What is the lead time and what support is included?
The ATO Sieve is configured to order — screen mesh, oxygen-sensor option and container fit are set for your powder — so lead time depends on the configuration; request the current lead time with your quote. Every ATO Sieve from Additive Plus includes install, commissioning and operator training, and we run the ATO powder chain in-house through AO Metal / ATO Lab, so support comes from a team that operates this equipment.
