Company Portrait: Weller Feinwerktechnik – Pioneering Work in Additive Manufacturing

Weller Feinwerktechnik GmbH from Wetzlar stands for the highest precision and innovative solutions in the manufacturing industry. With the advanced technology of powder bed fusion laser beam melting (LPBF), the company not only offers the possibility of producing complex and highly specialized components, but also provides its customers with comprehensive expertise in development and design for the successful implementation of customer projects using additive manufacturing.

The LPBF technology used by Weller enables the production of components that far exceed traditional manufacturing methods in terms of complexity and geometry. With the TRUMPF TruPrint 2000 machine and a build chamber of Ø200 x 200 mm, Weller can manufacture highly precise components from stainless steel 316L (1.4404). Layer thicknesses of 20 µm and 40 µm as well as a laser spot size of 55 µm ensure the highest precision. This technology is employed in various industries such as aerospace, medical technology and motorsports, where lightweight design and functional integration are critical.

Weller Feinwerktechnik distinguishes itself through its comprehensive experience in the design and optimization of components for additive manufacturing. The company works closely with its customers to shape the design so that it is both manufacturing-compliant and optimized for the specific application area. This includes, among other things, careful strength analysis that ensures additively manufactured components meet the requirements in their later field of application. This requires not only deep technical understanding but also a high degree of creativity and innovative spirit. Furthermore, the design department of Weller Feinwerktechnik prepares feasibility studies and value analyses for its customers.

A unique advantage of Weller Feinwerktechnik is the complete post-processing of components in-house. After 3D printing, the support structures are removed, followed by surface treatments such as tumble finishing, glass bead blasting, and polishing. For functional surfaces, the components are further processed on high-precision CNC machines. These steps are crucial to prepare the components for the high demands of the respective application.

Additionally, Weller offers specific and high-quality surface finishing, such as decorative and precise anodizing. This comprehensive process ensures that the end products are not only aesthetically appealing, but also functional and durable.

Another highlight in Weller Feinwerktechnik's product range is hybrid construction. This innovative method combines the advantages of additive manufacturing with traditional manufacturing techniques. Particularly in the production of special tools for turning operations, this technique is used to produce tools with optimized cooling supply. Hybrid construction enables the creation of components that are superior to conventional products in terms of performance and efficiency.

Weller Feinwerktechnik places the greatest emphasis on quality assurance. Continuous process monitoring during manufacturing guarantees that every component meets the highest standards. The LPBF process monitoring analyzes quality parameters in the powder bed layer by layer using automated image processing. This ensures that the components are both structurally flawless and visually perfect.

The strength of Weller Feinwerktechnik lies not only in technical expertise, but also in close collaboration with customers. By involving Weller early in the development process, customized solutions can be provided that are perfectly tailored to specific requirements. Customers appreciate the partnership approach, which makes it possible to implement projects efficiently and successfully.

Weller Feinwerktechnik GmbH is a pioneer in additive manufacturing that combines technological innovation with comprehensive expertise and excellent customer service. Through the combination of state-of-the-art 3D printing technology, in-depth experience in design, and a holistic manufacturing philosophy, Weller offers its customers unparalleled added value.
