AMAZEMET, an innovator in metal power production is set to introduce its new Powder2Powder (P2P) atomisation system at Formnext 2024. The P2P system presents a versatile solution for recycling metal powders and manufacturing custom pre-alloy powders directly from powder feedstock.
This unique technology (Figure 1) combines plasma processing and ultrasonic atomisation to
transform irregular or oversized particles into highly spherical, satellite-free powders optimised for
additive manufacturing (AM). Unlike plasma spheroidisation, the P2P technology allows powder
size to be independent of the initial feedstock, making it the only technology capable of direct
atomisation of pulverised Ti-feedstock.
Extensive trials using +200 μm oversize and irregular Ti alloy powders have shown exceptional
results with the P2P system. Operating at a frequency of 40 kHz, the system consistently achieved
a powder morphology with an aspect ratio (D50) exceeding 0.95. The particle size distribution
(PSD) was precisely controlled, producing powders with D90 < 80 μm and yielding particles <63
μm at ≥80%. Nearly 97% of the resulting powder was suitable for AM processes, including Laser
Powder Bed Fusion (LPBF), Directed Energy Deposition (DED), and Electron Beam Melting (EBM),
highlighting the system’s potential to enhance sustainability in metal powder production.

Additionally, the P2P system can process blends of elemental powders, creating pre-alloyed
materials tailored to exact chemical compositions. This capability makes it invaluable for both
research and industrial applications. Tests conducted with Ti and 10% wt. Mo elemental powders
showed that both refractory elements formed homogeneous alloy powders during processing. Set
for release in Q1 2025, this patented technology addresses two critical challenges in the AM
industry—upcycling of powder waste and custom powder production—delivering advanced
functionality that surpasses traditional recycling methods.
Key Features:
- Particle Size Distribution Control – The system adjusts the particle size distribution (PSD), transforming under- and oversized particles into powder optimised for LPBF, DED, and other AM techniques
- Powder Morphology – By combining plasma-based technology for melting feedstock powders with ultrasonic atomisation to refine particle morphology, the system transforms irregular powders into highly spherical, satellite-free particles, enhancing performance in AM processes
- Powder Alloying – Blends of elemental powders or commercial alloys with minor alloying element additions can be used as feedstock for atomisation. Unlike in EIGA or plasma atomisation, new alloys can be rapidly developed without preprocessing, electrode casting, or wire drawing
- Multi-Material Capability – The system handles a wide range of metal powders, including steel, titanium, nickel, refractory alloys, and high-entropy alloys (HEAs), with the ability to create powders that meet specific AM feedstock requirements
- Sustainability and Efficiency – By converting otherwise unusable powders into AM-ready material, the P2P system minimises waste and supports sustainable manufacturing practices
Łukasz Żrodowski, inventor and CEO of AMAZEMET, explains, “The Powder2Powder system goes
beyond recycling. It gives manufacturers the ability to customise powder compositions, improve
powder sphericity, and optimise particle size distribution, solving critical issues in the AM industry.
We’re excited to debut this at Formnext 2024, where we’ll showcase how it can enhance the
efficiency and sustainability of powder-based manufacturing.”
Formnext 2024 attendees will be the first to experience this innovative system, which offers
a complete solution for both recycling and custom alloy powder production. Learn more about
