ATO Sieve Ultrasonic Metal Powder Sieving Station Under Argon
Sieve metal AM powder in an argon atmosphere, straight from the ATO atomizer powder container — ultrasonic vibration keeps the mesh open and the powder away from oxygen.
- Same powder container as the ATO atomizers — transfer under argon
- Screens chosen for your target cut · optional oxygen sensor
- Installation, training and US service included · free powder samples
- Lead time 8–12 weeks · 12-month warranty
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 or ATO Sparq. Sub-24h reply, NDA on request.

What the ATO Sieve is
The ATO Sieve is a compact, mobile powder sieving station from 3D Lab, designed for metal additive manufacturing and for the small powder batches an ATO atomizer produces. It works in an inert argon atmosphere, which suits both reactive and non-reactive AM metal powders.
The station takes the same powder container as the ATO atomizers, so freshly atomized powder moves from the atomizer to the sieve inside the argon shield and is protected from oxygen. High-frequency ultrasonic vibration prevents the screen from clogging and keeps throughput high, and after screening the ATO Sieve fills the powder container with argon. It is operated from a touch panel and can be equipped with oxygen sensors. 3D Lab upgraded the ATO Sieve in 2025.
Specifications

3D Lab does not publish mesh sizes, container volume or dimensions for the ATO Sieve; the screens are chosen for your powder and listed in the quotation.
What it does in the powder workflow
The ATO Sieve is the finishing step after atomization: it turns the powder that comes off the atomizer into the fraction your process uses.
| LPBF feedstock | a defined size cut for laser powder bed fusion |
| DED and laser cladding | coarser fractions, screened under argon |
| Reactive powders | classified without exposure to air between atomizer and screen |
| Alloy development | quick sieving of small batches of new compositions |
| Powder reuse | used AM powder re-screened before it goes back into the printer |
Because the sieve shares the atomizer powder container, there is no repackaging step at which a reactive powder would meet air.
How powder moves from atomizer to screen
Where the ATO Sieve stops — and what to take instead
The ATO Sieve is built for small, lab-scale batches; it is not a high-volume industrial classifier. It separates powder by size but does not remove fines stuck to particles, surface films or moisture — for that, take the ATO Pure. To make reactive powder safe for handling in air, add the Passivation Module. It works with the powder container of the ATO atomizers — the ATO Lab, ATO Sparq and ATO Noble; if you want to sieve powder from another source, ask us how it would be loaded before you order.
Make your own powder, measure it, print it
The ATO Sieve sits between atomizing and measuring: atomize on an ATO Lab, sieve to your cut under argon, check size distribution and sphericity on a CAMSIZER X2+, and print on an AO Metal LPBF printer. The atomizer, analyzer and printer are also offered together as the R&D Bundle.
See it running in California
Customers are welcome to see an ATO atomizer running in California, at UC Irvine (UCI). It is a practical way to judge ATO technology and the powder it makes before you plan the rest of the chain around it. Book a visit and we arrange the date with you.
