Additive manufacturing—particularly metal 3D printing using the Selective Laser Melting (SLM) process—is becoming a central component of product development at Arnold Umformtechnik, as further reported. The targeted use of this manufacturing technique drastically shortens development cycles while also opening up new creative possibilities for connection options. Metal 3D printing demonstrates its full potential, especially in functional prototypes and small-series production, as Arnold Umformtechnik has observed. Functional prototypes can be delivered just a few days after data set creation—entirely without tools and the associated high additional costs. The components are considered very strong, dimensionally accurate, and functional. Even complex geometries, such as metric threads or delicate internal structures, can be relatively easily produced using additive manufacturing.

Additive Manufacturing is Being Increasingly Expanded

A typical example from Arnold’s practice involves screw connections with defined hardness properties and additively manufactured connecting elements. They enable test series without time-intensive forming tools. Design ideas can thus be evaluated and specifically optimized at an early stage. “With additive manufacturing, we achieve not only enormous time advantages but also technical systems that would hardly be feasible with conventional methods,” notes Uwe Wolfarth, Senior Director Research & Development / IP at Arnold Umformtechnik. This is particularly true in the early design phases. Furthermore, the targeted production of pre-series parts (without setup effort and tooling costs) helps streamline processes and reduce costs. Currently, efforts at the Forchtenberg site are being intensified to invest in expertise and system competence to expand additive manufacturing as a strategic element in the long term. Connection technology, as well as feeding and processing technology, benefit from new approaches—for example, through topology-optimized lightweight components or combined material and geometry properties that bring unprecedented functionality to the field.
