VITORIA-GASTEIZ, Spain and GERSTHOFEN, Germany, Nov 10, 2026 – Loramendi & Aurrenak and ExOne are joining forces to advance industrial Core Making through a complete solution built around the final casting and its industrialization. The alliance will be officially presented at Formnext 2026, taking place in Frankfurt, Germany, from 17 to 20 November.

World-Leading Technology Pioneers

Loramendi & Aurrenak bring 53 years of leadership in Core Making, tooling, casting development and industrial automation, while ExOne, founder and pioneer of sand binder jetting, contributes more than three decades of experience in 3D sand printing for the foundry industry and more than 500 system installations worldwide. Together, they combine proven industrial leadership with breakthrough technology to advance the next generation of Core Making, from casting development to fully automated production. The objective is not to replace one Core Making technology with another, but to give foundries access to the right manufacturing technology for every core, every casting and every production requirement.

“Castings are becoming lighter, more complex and faster to develop, which requires a broader and more flexible Core Making approach. At Loramendi & Aurrenak, 3D printing gives us greater speed and flexibility in the early stages of casting development, while our Core Making, tooling and automation expertise provides the path to industrial production. With the S-Max Pro in Vitoria and ExOne’s technology, we strengthen our ability to develop and validate new castings in-house and take them efficiently from first concept to serial production.” Joseba Goitia, CEO, Loramendi & Aurrenak.

Adaptive Core Making: the right process for every core

Adaptive Core Making goes beyond the conventional concept of a hybrid solution. It means selecting and integrating the most suitable technology for each core, geometry, production volume and stage of the casting and product lifecycle. Conventional Core Making and sand 3D printing are complementary technologies, each bringing specific advantages to the complete industrial solution.

From concept to casting

The alliance strengthens Loramendi & Aurrenak’s ability to support customers from early product development through to full industrial production.

Printed sand packages enable rapid design iterations, prototype castings, first batches and component validation through Aurrenak’s casting-development capabilities.

The knowledge generated is then transferred into optimized coreboxes, permanent moulds, Core Making equipment, automation and complete production installations.

“Our experience shows that the strongest business cases start with the casting itself. By combining ExOne’s sand 3D printing with Loramendi & Aurrenak’s casting, Core Making and automation expertise, customers can identify the right applications and scale them efficiently from development into series production.” said, Eric Bader, CEO, ExOne.

Additive manufacturing and conventional Core Making are therefore not competing alternatives, but complementary technologies within the same industrial strategy, selected according to the needs of the casting, the core and the production volume.

Pioneers in Industrialization of Core Printing (ICP)

Loramendi brings proven expertise in automating and industrializing the complete Core Making process, turning new manufacturing technologies into robust serial-production systems. This includes unpacking, cleaning, handling, coating, inspection, assembly, logistics and full line integration.

Loramendi and ExOne have already proven this together. In the joint Industrialization of Core Printing (ICP) project for BMW Group Plant Landshut, Loramendi’s automation and process engineering and ExOne’s sand 3D printing technology came together in the world’s first fully automated additive production line for sand cores in serial production.

Together, ExOne’s printing technology and Loramendi’s process engineering, automation and system-integration expertise connect the printed core to a complete industrial manufacturing process.

A complete Core Making and casting solution

Loramendi & Aurrenak, together with ExOne, offer customers a uniquely broad technology portfolio covering:

• printed and blown sand cores;
• core blowing machines and complete core shops;
• coreboxes, production tooling and permanent moulds;
• gravity, low-pressure and high-pressure aluminium casting technologies;
• sand-package solutions for aluminium, iron and steel;
• casting trials, prototypes and first-part validation;
• core handling, finishing, assembly and complete automation.

Loramendi & Aurrenak’s key advantage is their ability to engineer the manufacturing strategy around the final casting, connecting the core, tooling, casting process and automation in one industrial solution.

S-Max Pro in Vitoria-Gasteiz

ExOne will install an S-Max Pro industrial sand 3D printer at Loramendi & Aurrenak’s facilities in Vitoria-Gasteiz. The system will support:

• prototype and new-part development;
• printed sand-package production;
• customer benchmarks, casting trials and first batches;
• development and validation of automated post-processing solutions;
• demonstration of Adaptive Core Making workflows.

The S-Max Pro will connect ExOne’s additive technology with Aurrenak’s casting and tooling capabilities and Loramendi’s Core Making machinery and automation expertise.

Official representation in Spain and Portugal

Loramendi & Aurrenak will become official ExOne representatives in Spain and Portugal. Customers will gain one regional partner for sand printing, casting development, Core Making, tooling, automation and industrial integration.

Through their subsidiaries and international service networks across five continents, the companies will provide worldwide support for local development projects and global production programs, combining European technology with close-to-customer execution.

A new standard for Core Making

The alliance reinforces the role of Loramendi & Aurrenak and ExOne as technology drivers in the evolution of global Core Making. By integrating ExOne’s sand 3D printing technology with conventional Core Making, casting expertise, tooling and industrial automation, the companies create a complete reference for the future of Core Making — not based on replacing one technology with another, but on selecting, integrating and industrializing the right process for every casting.
