About this product
ATO Noble is an ultrasonic metal powder atomizer engineered specifically for precious and noble metals — gold, silver, platinum, palladium and iridium. It melts wire, rod or scrap feedstock and atomizes it into fine, spherical powder inside an inert argon atmosphere, while Zero Loss Technology — a dedicated filtration system and closed-loop gas circulation — recovers nearly all of the high-value metal. Because chemistry and karat are preserved through atomization, jewelers and refiners can turn certified stock and offcuts into printable powder in-house, without sending precious material out for refining.
Why jewelers and refiners choose ATO Noble
Spec-backed reasons a precious-metal shop atomizes in-house instead of buying powder or sending scrap out.
Zero-loss recovery on high-value metal
A dedicated filtration system and closed loop of inert-gas circulation capture nearly all the atomized metal and unused feedstock. On gold and platinum, minimizing loss is the whole economic case for atomizing in-house.
Karat & chemistry preserved
Chemical composition stays the same after atomization, so the powder holds the precious-metal standard of the input stock. Ultrasonic melting under argon (oxygen <0.1%) keeps hallmarking and assay integrity intact.
Spherical, high-flow powder
Ultrasonic atomization yields near-spherical particles with high flowability and consistent morphology. Particle size is set by frequency — 35 kHz standard, upgradeable to higher frequency for finer fractions — not by chance turbulence.
Purpose-built for precious & noble metals
Runs Au 9ct / 18ct / 99.99%, silver, platinum, palladium, iridium and custom precious alloys from wire, rod or scrap — a machine tuned for the metals bulk gas-atomization towers are not built to handle economically.
From your metal to first powder
How Additive Plus configures, installs and dials in ATO Noble around your precious alloys.
Step 01
Configure to your metals
We spec the TIG melting source, cooled nanoalloy sonotrode, ultrasonic frequency and feeding system around the precious metals and feedstock forms — wire, rod or scrap — you actually run.
Step 02
Install & commission
Delivered with external chiller, argon supply and cyclone recovery defined. We install, run first powder, and train your team on the atomization, recovery and inert-atmosphere workflow.
Step 03
Dial in zero-loss batches
We map frequency-to-particle-size for your metals and integrate ATO Sieve and characterization so recovered gold, silver or platinum comes out print-ready — not just atomized.
Atomization Technology & Powder Quality
ATO Noble breaks molten precious metal into fine droplets with a cooled nanoalloy sonotrode, solidifying them into spherical particles under an argon atmosphere. Particle size is selected through the ultrasonic frequency, giving reproducible fractions for downstream powder metallurgy, MIM, HIP and metal AM.
The atomization method is patent-protected. 3D Lab holds granted patents for producing spherical metal powder by ultrasonic atomization in the United States (US 12,090,554 B), Poland, China, Japan, South Korea and India, with further sonotrode and powder-evacuation patents pending — so this is a protected process engineered for precious metals, not a generic ultrasonic rig.

Common questions

Which metals can ATO Noble atomize?
ATO Noble is purpose-built for precious and noble metals — gold (9ct, 18ct and 99.99%), silver, platinum, palladium and iridium, plus custom precious alloys. It melts wire, rod or scrap feedstock and atomizes it ultrasonically into fine spherical powder. Because the process is tuned for high-value metals rather than bulk industrial alloys, it prioritizes recovery and chemistry control over raw throughput. If you have a specific karat or platinum-group composition, our applications engineer can confirm it runs on ATO Noble before you commit.
How does Zero Loss Technology reduce precious-metal waste?
ATO Noble uses a Zero Loss design — a specially adapted filtration system combined with a closed loop of inert-gas circulation — to capture nearly all of the atomized metal and recover unused feedstock for reuse. On precious metals, where a few grams of gold or platinum represent real money, minimizing loss is the whole economic case for atomizing in-house. The result is a high powder-flow ratio, efficient recovery of fines, and a closed-loop workflow that turns scrap and offcuts back into printable powder instead of sending them out for refining.
Does atomization change the karat or chemical composition?
No. A key advantage of ATO Noble is that the chemical composition — and therefore the karat — stays the same after atomization, so the powder holds the precious-metal standard of the input feedstock. Ultrasonic atomization under an inert argon atmosphere (oxygen below 0.1%) melts and breaks the metal into droplets without alloying it with the surroundings. This lets jewelers and refiners convert certified stock into powder and back into finished parts while keeping hallmarking and assay integrity intact.
What powder quality and particle size does ATO Noble produce?
ATO Noble produces fine, near-spherical powder with high flowability and consistent particle morphology — the qualities powder metallurgy, MIM, HIP and metal AM depend on. Particle size is set by the ultrasonic frequency: the standard 35 kHz sonotrode can be upgraded to higher frequencies (with the Smart generator) for finer fractions, since higher frequency yields smaller particles. The cyclone collector and integrated sieving unit sort the powder into usable fractions. For a target particle size distribution on your specific metal, our engineer can advise the frequency configuration.
What melting and atomization technology does ATO Noble use?
ATO Noble melts feedstock with a TIG source and can drive plasma current up to 250 A, then transmits ultrasonic vibration through a cooled nanoalloy sonotrode (up to 800 W) into the molten pool. The vibration ejects fine droplets that solidify into spherical particles in an inert argon atmosphere. The method is patent-protected — 3D Lab holds granted ultrasonic-atomization patents in the United States, Poland, China, Japan, South Korea and India — so ATO Noble is a protected process engineered for precious metals, not a generic ultrasonic rig.
What infrastructure is required to install ATO Noble?
ATO Noble runs on a 400 V, 3-phase supply drawing up to 20 kVA, with argon as the process gas and 4–8 bar compressed air. It needs an external liquid chiller (cooling is closed-loop) and floor space for a 600 kg system measuring 78.7 × 43.3 × 29.9 in / 2000 × 1100 × 760 mm. No dedicated powder plant or industrial gas-atomization tower is required — it installs in a workshop or materials lab. Additive Plus defines the chiller, gas and collection setup and commissions the system on site, so facilities and procurement can plan the install from these figures.
Can Additive Plus run a paid trial atomization before we buy?
Yes. Send us your target precious alloy and our in-house ATO Lab / AO Metal cell runs a paid trial atomization, returning spherical powder plus particle-size, chemistry and flow data so you can qualify the process and the recovery yield before committing to a system. Because we operate ultrasonic atomization ourselves, we can advise on melting module, sonotrode frequency and expected loss for your specific metal. It is the lowest-risk way to prove the economics of in-house precious-metal powder before a capital purchase.
How does ATO Noble fit into a full precious-metal powder workflow?
ATO Noble is the atomizer at the front of a closed powder loop. Downstream it pairs with the ATO Sieve sieving station for print-ready fractions, a Microtrac CAMSIZER particle analyzer for QC, and an AO Metal printer to print the powder into finished jewelry or components — the same chain sold as our AO Metal + ATO Lab jewelry bundle. Additive Plus supplies and supports the whole workflow under one partner, so recovered gold, silver or platinum powder goes from scrap to certified part without leaving your facility.
