FKM Sintertechnik produces highly complex plastic stocks for ANSCHÜTZ biathlon rifles

The rapid realization of small and medium batch sizes of ready-to-install plastic parts with high requirements in terms of geometric complexity is now considered one of the key areas of additive manufacturing technology. Why selective laser sintering (SLS) continues to be one of the leading shaping processes in this field can be illustrated by the example of the production of the stocks for the biathlon sports rifles of the German company J.G. ANSCHÜTZ. They are manufactured in series at the FKM Sintertechnik plant.

“In our laser sintering factory in Biedenkopf, Hesse, we use it to produce prototypes and pre-series as well as series of plastic and metal components for automotive engineering, electrical engineering, the consumer industry and all segments of mechanical and plant engineering,” explains Managing Director Jürgen Blöcher.

ANSCHÜTZ’s decision to rely on selective laser sintering for the production of these shafts was based on the need to use a flexible and cost-efficient manufacturing method that can realize the high geometric complexity of the shaft. FKM Sintertechnik relies on a special material based on polyamide 12, which is characterized by its robustness and temperature resistance. This allows the shaft to be printed in various colors and surface qualities, as well as the production of individualized grips and metacarpal supports with a lattice structure.

“Numerous lightweight construction aspects, for example, which are implemented in the production of sports rifle stocks, also come into play in the production of series parts for other industries,” emphasizes Jürgen Blöcher.

The precision and flexibility of the SLS process allow the complex geometry of the rifle stock to be realized in great detail, including all the necessary curvatures, recesses and mounting options. The result is a highly functional, customizable and aesthetically pleasing product.

This cooperation between J.G. ANSCHÜTZ and FKM Sintertechnik impressively demonstrates how advanced 3D printing technologies can enable innovative solutions not only in industry, but also in top-class sport. The successful implementation of this project confirms selective laser sintering as a key technology for the production of high-precision, customized and functional components.
