    With its new Röchling Direct Manufacturing Center in Waldachtal, Röchling is embarking on a journey into the future.

    Additive processes offer Röchling Medical the unique opportunity to manufacture prototypes and complex components in small and medium-sized quantities quickly, individually, and economically without tools, i.e. fixed costs. The following technologies are used:

     

    Printing with plastic granulate in "freeformers".

    Standard plastic granulate is liquefied via nozzles and applied as droplets to the workpiece which is positioned under the nozzle. The process can be used under normal and clean room conditions. Since the plastic is applied from a nozzle in a similar way to injection molding, it is possible to produce components from the original material and thus decisively shorten the development time.

     


    Printing with plastic powder and ink.

    Components are produced in large quantities and with a maximum installation space of 300 x 300 x 300 mm (e.g. made of polyamide).­

     


    Printing with photopolymers.

    Components are produced from a color palette with more than 500,000 colors. Photorealistic prototypes can be used in medical technology, for example in ergonomics studies. In addition, hard-soft combinations allow the production of functional prototypes.

     


    Printing with metal powders.

    Metal powders are laser-exposed in such a way that the desired shape is created from them. Components made of tool steel, aluminium, stainless steel and even titanium are relevant for medical technology.

     


    Printing with plastic powders.

    Components with special properties are produced here. For example, it is possible to produce liquid-repellent components by subsequent impregnation.

     


    Printing with plastic filaments.

    Components are manufactured using the fused deposition process. Special filaments certified for the medical sector allow the additive production of components for medical use with complicated geometries.
