The VX9000 sand binder jetting 3D printer, developed via a strategic collaboration between voxeljet, GE Vernova, and Fraunhofer IGCV, has been used for the primary profitable casting of large-scale sand molds at Baettr Foundry. This milestone underscores the transformative potential of the world’s largest binder jet 3D printer because it enters the subsequent part of fresh power manufacturing. Designed by voxeljet particularly for large-format functions in wind and hydro power sectors, the VX9000 is a de facto recreation changer.
The profitable casting of benchmark molds—every extending as much as 9.5 meters—demonstrates the VX9000’s readiness for real-world industrial use. These castings preserve dimensional accuracy inside anticipated ranges, a vital think about high-precision functions similar to turbine part manufacturing. Much more considerably, the pouring course of was carried out below genuine foundry circumstances, mimicking real-world manufacturing environments and validating the robustness of the VX9000 system.
The preliminary observations from this trial—concerning workflow, dealing with, and efficiency—are actually guiding additional refinements. These learnings shall be built-in into the manufacturing pipeline, streamlining the system for broader industrial adoption.
VX9000: engineered for scale and precision
Initially offered in 2021, the VX9000 has been meticulously engineered to provide near-net form (NNS) elements important for the power sector’s largest and most complicated infrastructure. Its sheer scale permits for the printing of sand molds that may in the end change into turbine nacelles—elements weighing upwards of 60 metric tons.
This cutting-edge expertise has been below improvement as a part of the U.S. Division of Vitality’s Superior Casting Cell (ACC) initiative. Backed by $14.9 million in federal funding, the ACC goals to expedite America’s transition to sustainable power by modernizing and digitalizing the manufacturing provide chain. By lowering the time required for mildew manufacturing from ten weeks to only two, the VX9000 provides an unprecedented acceleration of the manufacturing timeline. It’s anticipated to chop hydropower prices by as much as 20% and lead instances by as a lot as 4 months—a rare enchancment in effectivity.
Throughout this part, voxeljet efficiently printed 20 benchmark sand molds, every tailor-made to be reworked into metallic elements utilized in clear power functions. That is notably essential for generators just like the GE Haliade-X, which not too long ago set a world report by producing 312 megawatt-hours of electrical energy in simply 24 hours. The nacelle of this turbine, made utilizing the VX9000’s molds, is emblematic of the dimensions and precision required in right this moment’s renewable power infrastructure.
A collective imaginative and prescient for a clear power future
The VX9000’s improvement is a collaborative achievement involving a few of the most revered names in business and academia. GE Hydro, GE Onshore Wind, GE Offshore Wind, Clemson College, Oak Ridge Nationwide Laboratory (ORNL), and Hodge Foundry are all key companions within the Superior Casting Cell initiative. Collectively, these establishments are constructing a whole digital foundry ecosystem—one which spans from preliminary CAD design to the ultimate metallic half.
This ecosystem contains digital workflow optimization, robotic welding applied sciences, and workforce improvement applications to equip the subsequent era of technicians with superior manufacturing abilities. As an illustration, the event of a robotic welding resolution for assembling a >10-ton Francis runner is underway, alongside casting optimizations for a 16-ton rotor hub. These efforts are all geared towards making america a frontrunner in cost-effective, home manufacturing of large-scale power infrastructure elements.
Because the VX9000 continues to evolve, its impression is turning into more and more evident. It’s not only a printer; it’s a cornerstone of the power sector’s digital transformation. This milestone at Baettr Foundry illustrates how scalable additive manufacturing can fulfill the formidable targets of a clear power financial system.
