AMAZEMET, a Warsaw-based firm, unveiled its modern Powder2Powder (P2P) atomization system at Formnext 2024. This new system affords a flexible answer for recycling steel powders and producing customized pre-alloy powders straight from current powder feedstock, marking a big development in sustainable steel powder manufacturing for the 3D printing business.
The Powder2Powder system integrates plasma processing with ultrasonic atomization, reworking irregular or outsized particles into extremely spherical, satellite-free powders optimized for numerous 3D printing methods reminiscent of Laser Powder Mattress Fusion (LPBF), Directed Vitality Deposition (DED), and Electron Beam Melting (EBM). Not like standard plasma spheroidization strategies, the P2P expertise permits powder measurement to stay impartial of the preliminary feedstock. This functionality makes it the one expertise at present able to straight atomizing pulverized titanium (Ti) feedstock, setting a brand new benchmark in powder processing, in line with the corporate.
In depth trials with over 200 μm outsized and irregular Ti alloy powders demonstrated the system’s distinctive efficiency. Working at a frequency of 40 kHz, the P2P system constantly achieved a powder morphology with a facet ratio (D50) exceeding 0.95 and a exact particle measurement distribution (PSD), producing powders with D90 beneath 80 μm and yielding particles underneath 63 μm at or above 80%. Roughly 97% of the ensuing powder meets the stringent necessities for additive manufacturing processes.
Past recycling, the P2P system excels in processing blends of elemental powders to create pre-alloyed supplies with exact chemical compositions. This function is invaluable for each analysis and industrial functions, permitting for the speedy growth of recent alloys with out the necessity for in depth preprocessing, electrode casting, or wire drawing. Checks with Ti and 10% wt. Mo elemental powders confirmed the formation of homogeneous alloy powders, demonstrating the system’s versatility and effectivity.
Łukasz Żrodowski, inventor and CEO of AMAZEMET, said, “The Powder2Powder system goes past recycling. It provides producers the flexibility to customise powder compositions, enhance powder sphericity, and optimize particle measurement distribution, fixing essential points within the additive manufacturing business. We showcased the way it enhances the effectivity and sustainability of powder-based manufacturing at Formnext 2024.”
Trade Advances in 3D Printing Supplies
On the similar occasion, PowderMonkeys, a model of Launhardt GmbH specializing in polymer powders for powder mattress fusion (PBF) processes, launched two superior supplies: Monkey SiPA12 and Monkey RePA12 50-8 GB. Established in 2021, PowderMonkeys provides supplies suitable with selective laser sintering (SLS) and high-speed sintering (HSS) platforms. Monkey SiPA12 is engineered for Sintratec machines, providing excessive mechanical power and decreased waste, whereas Monkey RePA12 50-8 GB incorporates glass beads to reinforce tensile power and thermal stability, offering a shiny end superb for functions requiring each mechanical resilience and aesthetic high quality.
Stratasys, a number one 3D printer producer, additionally offered SAF ReLife, an answer that repurposes waste PA12 powder into 3D printed components. Supported by a Life Cycle Evaluation from Fraunhofer IPA, SAF ReLife reduces the carbon footprint of 3D printing by as much as 89%. This platform leverages Stratasys’ H350 powder mattress fusion 3D printer to provide useful components from reclaimed powder, enhancing materials effectivity and supporting the round financial system by changing waste into high-quality merchandise.
