Seamless and Rapid Integration of the DMP Flex 350
One of the most remarkable aspects of Krüger’s foray into metal additive manufacturing was the astonishing speed with which the DMP Flex 350 was integrated into their existing operations. The Krüger teams reported an installation period of merely one week, an exceptionally short timeframe for a sophisticated industrial machine. Friedhelm Krüger, Managing Director of Krüger Fertigungstechnologie, expressed his profound satisfaction and astonishment: “I am truly impressed with the speed and fluidity with which the GF Machining Solutions team established metal 3D printing for us. The printer was not only installed and commissioned but our staff were also fully trained within an astonishingly short period of just one week. Thanks to the DMP Flex 350, we are now capable of offering our customers an even wider, more advanced, and highly specialized range of services.” This rapid deployment underscores the efficacy of GF Machining Solutions’ support and the inherent design of the DMP Flex 350 for streamlined industrial implementation.
This expedited integration, however, was not solely due to the efficiency of GF Machining Solutions. Krüger’s existing foundational expertise in 3D modeling and a deep understanding of general manufacturing processes played a crucial role in the seamless transition. Robert Volland, a sales engineer at GF Machining Solutions, affirmed this, stating: “Before implementing any new machine, we meticulously analyze the customer’s specific training needs. Krüger already possessed considerable experience with modern 3D software and a strong grasp of design principles, allowing us to leverage this existing knowledge and build upon it effectively during the training phase.” Today, the DMP Flex 350 machine operates synergistically with 3DXpertTM software, a powerful tool specifically engineered to streamline and optimize the entire metal additive fabrication process. Krüger has particularly benefited from 3DXpert’s automatic alignment functionality, which not only enhances part quality by ensuring precise placement and orientation but also intelligently optimizes the build volume’s utilization. This allows for the simultaneous creation of multiple components, maximizing throughput and efficiency. Friedhelm Krüger further elaborated on the economic advantages: “This significantly saves us money – a saving that we are delighted to pass on to our customers, strengthening our competitive edge. The optimization of support structures is also an integral part of this automatic process. They are generated concurrently with the part design, meticulously considering factors such as optimal part support, efficient material consumption, and minimized printing time, all contributing to a more economical and reliable production cycle.” This sophisticated software integration underscores the full potential of GF Machining Solutions’ holistic AM ecosystem.

Elevating Manufacturing Capabilities and Design Freedom
The investment in metal additive manufacturing represents a significant leap forward for Krüger Fertigungstechnologie, empowering them to combine multiple advanced manufacturing processes and dramatically expand the possibilities for all their customers. This strategic move allows Krüger to transcend the limitations of traditional manufacturing by creating sophisticated hybrid parts that seamlessly integrate the unparalleled advantages of metal additive manufacturing with the precision and established reliability of more conventional methods, which the company has mastered for over two decades. Hybrid manufacturing, in this context, means designing components where 3D printed sections, often featuring complex internal geometries, lightweight structures, or integrated functionalities, are combined with machined surfaces that demand extremely tight tolerances and superior surface finishes. This synergistic approach enables Krüger to offer components that are lighter, stronger, more efficient, and often consolidate multiple parts into a single, optimized assembly.
A compelling example of this advanced capability is Krüger’s involvement in the ambitious ITER (International Thermonuclear Experimental Reactor) project. This monumental scientific collaboration brings together 35 countries with the shared goal of designing, building, and operating the world’s largest tokamak – an experimental machine designed to harness the energy of fusion, mimicking the processes that power the sun. For such a critical and technologically demanding project, Krüger has innovatively conceived a complex heat exchanger as a single, fully integrated piece. This component leverages the strengths of both 3D printing and precision milling. Additive manufacturing enables the creation of intricate internal channels and optimized fin structures within the heat exchanger, drastically improving its thermal efficiency and reducing its overall weight and footprint – factors that are paramount in advanced energy applications. Following the printing process, targeted milling operations ensure critical interfaces and mounting points achieve the exact dimensional accuracy and surface quality required for the reactor’s stringent operational standards. This ability to produce highly specialized, performance-optimized components demonstrates the transformative potential of Krüger’s new AM capabilities in addressing global technological challenges.
Beyond specific projects, the strategic adoption of metal AM and the associated 3DXpert™ software workflow significantly broadens Krüger’s service portfolio. They can now undertake projects requiring bespoke parts with intricate internal cooling channels for aerospace applications, lightweight yet robust components for automotive performance, or customized medical implants with optimized porous structures for biocompatibility. The flexibility to integrate additive manufacturing into existing production lines enhances their value proposition, allowing them to serve diverse industries with tailored, high-performance solutions. This positions Krüger not just as a subcontractor, but as an innovation partner for their clients, capable of co-creating designs that were once considered impossible or economically unfeasible. The ability to iterate quickly from design concept to physical prototype, coupled with the precision of subsequent milling, drastically reduces development cycles and time-to-market for new products, offering a substantial competitive advantage.
Friedhelm Krüger eloquently summarizes the overarching benefit: “The easy integration of other manufacturing technologies is an enormous advantage for us. With 3DXpert, we can effortlessly manufacture hybrid parts, such as 3D printed components that still require precise post-milling operations to achieve final specifications. This flexibility allows us to deliver superior quality and performance that aligns perfectly with our customers’ demanding requirements.” This statement perfectly encapsulates the synergy between additive and subtractive manufacturing that Krüger has mastered, ensuring maximum efficiency and unparalleled product quality. The strategic partnership with GF Machining Solutions has not only expanded Krüger’s manufacturing capabilities but has fundamentally transformed their approach to engineering and production, setting a new benchmark for innovation in subcontracting manufacturing.
