Renishaw, a number one engineering expertise firm, has partnered with Cookson Industrial, a UK-based specialist in treasured steel additive manufacturing (AM), to scale back the prices related to 3D printing platinum-rhodium. This collaboration leverages Renishaw’s RenAM 500S Flex AM system, enabling Cookson Industrial to provide high-temperature corrosion-resistant elements with improved materials effectivity. The development is especially vital for industries comparable to glass fibre manufacturing, the place the viability of utilizing platinum rhodium in additive manufacturing has been enhanced.
Cookson Industrial, a division of Cooksongold and a subsidiary of HM Valuable Metals, brings over three a long time of experience in designing and producing treasured steel alloys. Confronted with platinum rhodium costs averaging £80,000 per kilo, minimizing materials waste was important to make manufacturing economically possible. To handle this problem, Cookson Industrial chosen Renishaw’s RenAM 500S Flex, a laser powder mattress fusion system designed for analysis and improvement in additive manufacturing.
Renishaw’s AM engineering crew collaborated carefully with Cookson Industrial to adapt the RenAM 500S Flex for platinum rhodium manufacturing. Whereas the usual system achieves powder waste ranges as little as 1.5%, customized modifications had been needed to scale back waste to under 0.5%. “Reaching near-zero wastage of platinum rhodium powder was a high precedence,” said Jason Morgan, Senior Purposes Engineer at Renishaw. “We labored with Cookson’s engineers to establish and get rid of potential powder traps throughout the system, adopted by fast testing and redesigns to attenuate waste with out compromising efficiency.”
The customization course of concerned modifying inside system elements to stop powder accumulation. This included eradicating overflow bellows and optimizing the rear overflow vent. Extra measures encompassed chamber redesigns and the creation of specialised casings and covers. These modifications resulted in a 95% discount in powder waste, permitting Cookson Industrial to get better almost all platinum rhodium powder. This substantial lower in materials loss interprets to vital value financial savings and enhances the industrial viability of large-scale manufacturing.
Nikesh Patel, Head of Cookson Industrial, commented, “Renishaw’s expertise and experience had been essential to this R&D success, enabling us to provide platinum rhodium components on a industrial scale. Minimizing powder loss not solely reduces our manufacturing prices but additionally makes large-scale manufacturing possible, saving thousands and thousands over the machine’s lifetime.”
Valuable Metals in Industrial AM and Metallic Powder Manufacturing
Cooksongold not too long ago launched Cookson Industrial, a division devoted to integrating treasured metals into industrial AM sectors comparable to aerospace and healthcare. Its facility in Birmingham consists of a number of EOS Valuable M methods and a RenAM 500S Flex, enabling the manufacturing of gas-atomized treasured steel powders in small batches as much as 15kg. A £750,000 grant from the Engineering & Bodily Sciences Analysis Council (EPSRC) helps the event of specialised treasured steel alloys on the College of Birmingham, with a concentrate on excessive environments.
3D Lab, a Warsaw-based service bureau, is introducing the ATO Suite at Formnext 2024. This modular set of apparatus manages steel powder manufacturing from feedstock preparation to closing refinement. The ATO Lab Plus, ATO Noble, and associated methods allow customized powder manufacturing, reuse of scrap supplies, and management over particle measurement distribution. The gear occupies a small footprint and consists of vacuum casting and ultrasonic sieving choices. Such configurations can assist the dealing with of high-value supplies by bettering powder high quality and minimizing contamination.
