Friedberg, Germany, October 25th, 2023 —

voxeljet AG (NASDAQ: VJET) and Loramendi demonstrate the world’s first fully automated additive serial 3D production line for sand cores, jointly developed as part of the Industrialization of Core Printing (ICP) cooperation project. A new video released today features the implementation of the first ICP production line at BMW Group’s (OTCPK:BMWYY) plant in Landshut, Germany. As BMW Group’s largest component plant, Landshut has approximately 3,500 employees and supplies all of its vehicle and engine plants worldwide, including for nearly all BMW, MINI and Rolls-Royce vehicles, and for its motorcycle brand, BMW Motorrad.

The customized, low-emissions solution integrates voxeljet’s high-speed VX1300-X (VJET-X) 3D printers into a fully automated pre- and post-processing workflow, including industrial microwaves for curing the 3D printed cores. Printing rates were increased by factor ten with the latest generation of VJET-X 3D printers, and the toolless design of the sand cores allowed for variant changes at unprecedented speed without time-consuming tool changes and production downtime. The unused material is 100% recycled and reused in the production process.

“The fully-automated 3D production line at BMW’s Landshut plant is a key milestone not only for voxeljet, but for the entire 3D printing and automotive industry,” said Dr. Ingo Ederer, founder and CEO of voxeljet. “We believe this customized, near-zero emissions solution achieved in partnership between voxeljet, Loramendi and BMW will become an industry standard.”

Together, voxeljet and Loramendi are revolutionizing the industrialization of core printing. The production of inorganic 3D printed cores has enabled BMW Group to advance the design of its engine components. For example, the cylinder head for BMW’s B48 engine has been significantly improved by using 3D printing to produce water jacket – outlet combi cores. Additionally, 3D printing allows BMW to produce sand cores in one piece, reducing the complex design of engine components while optimizing the engine’s efficiency and fuel consumption. The inorganic 3D production line also significantly reduces the foundry’s emissions, as only water steam is produced during the casting process.

voxeljet’s powerful next-generation binder jetting 3D printing technology offers the highest additive productivity and throughput to meet the demands of BMW’s large-scale production needs. voxeljet’s layer-by-layer technology works by using sand and an inorganic binder. A print head selectively bonds layers of sand to create the cores, which are then unpacked, microwave cured, cleaned and inspected before being fed into BMW’s established casting process. voxeljet has been granted 1 patent and has 10 patent families with 28 patent applications across the United States, Europe, and other geographies that protect this proprietary approach.

Friedberg, Germany, October 11th, 2023 – GE Research has selected voxeljet (NASDAQ: VJET) as its partner for the U.S. Department of Energy’s (DoE) $14.9 million award in federal funding for the development and commercialization of a large sand binder jet 3D printer, called Advanced Casting Cell (ACC), to accelerate the United States’ transition to clean power. In addition to voxeljet, GE Research has also selected GE Hydro, GE Onshore Wind, GE Offshore Wind, Clemson University, Oak Ridge National Laboratory (ORNL), and Hodge Foundry as partners on the ACC project.

The Advanced Casting Cell project was established to strengthen the U.S. manufacturing industry and expertise to boost the cost-effective domestic production of large metallic near net shape (NNS) components in alignment of the Biden Administration’s clean power-generation strategy. The ACC will be developed and deployed to produce sand molds to manufacture metallic NNS parts. With development of the ACC, the project includes the digital creation of mold designs via a digital foundry as well as the completion of a techno-economic analysis of cost and supply chain challenges.

The project aims to produce 3D-printed large scale sand molds to cast components for the nacelle of the GE Haliade-X Offshore Turbine. The nacelle, where mechanical components are housed, can weigh more than 60 metric tons. The goal is to reduce the time it takes to produce this pattern and mold, from around ten weeks to two weeks. According to Data Bridge Market Research, the global wind turbine nacelle market has estimated to be valued at $6.6 billion in 2021 and projected to be over $15 billion by 2029.

This novel manufacturing technology has the potential to reduce overall hydropower costs by 20% and lead times by four months. The project will also include the production optimization of a 16-ton rotor hub using the ACC as well as the development of a robotic welding process for the assembly of a >10-ton Francis runner. To help ensure successful implementation of ACC, an advanced manufacturing curriculum is being created for local workforce development to train and engage workers on the specifics of this 3D printing manufacturing technology.

“We’re excited to be a part of this future-driven and innovative project,” said Dr. Ingo Ederer, CEO of voxeljet. “The development and cost-efficient manufacturing of clean power-generation technologies is in high-demand because it is key to meeting and overcoming global climate challenges. We are confident that additive manufacturing, and specifically our large-scale Binder Jetting technology, is the right choice to manufacture complex parts used in these next-generation wind turbines.”
