Post-processing activities

As the saying goes: we save the best for last. That is why the final machining of your components requires true professionals. This is where personal experience and manual dexterity count for a lot more than in all the previous manufacturing steps. Most finishing technologies are not performed by machines, they remain the domain of genuine craftsmanship. While we continue to drive the further development of our industrial processes in additive manufacturing, we maintain a factory culture in the post-processing department. Precision and perfection are the name of the game, as this is the only way to deliver on our mission to produce the perfect component for you.

Depending on the size of the component and the intended use, we can therefore reliably navigate through our numerous options to reach the goal in cooperation with you. We would be pleased to provide advice to help you decide on which technology is best suited for meeting your requirements.

Hirtisation®

Hirtisation®

New in November: Hirtisation® is a patented technology that provides a fully automatic post-treatment process for 3D printed metal parts. With it, sintered-on particles and support structures are removed and the surfaces are smoothed. Hirtisation is suitable for all metals and alloys commonly used in 3D printing.

High pressure heat treatment

New in November: High Pressure Heat Treatment (HPHT) is an innovative technology used for the consolidation and densification of metal, ceramic, and plastic parts. Typical pressures of 15,000 - 30,000 psi, temperatures of up to 4,000 °F, as well as cooling rates of up to 4,500 K/min allow for a maximum theoretical density, ductility, and fatigue resistance of high-performance materials.

Metal coating

Metal coating

Metal coating is the optical or functional improvement of 3D printed plastic and metal parts by electroplating. Our four galvanizing tanks allow components to be partially or completely coated with copper, nickel, or other materials. Metal coating is used to improve the mechanical and electrical properties, for example, it increases the long-term dimensional stability, strength, and stiffness, ensures outstanding conductivity and appealing metallic esthetics.

Infiltrating

Infiltrating improves the product properties of plastic components from selective laser sintering (SLS) by applying epoxy resin and subsequent hardening. The resin penetrates into the surface and creates a higher stability, stiffness, and moisture resistance in the component.

Blasting

Blasting

Blasting is a mechanical procedure for finishing surfaces, e.g. to clean and homogenize. Various blasting material is available, glass beads for roughening, corundum for harsher roughening, and steel balls for smoothing.

Dipping

Primarily used to visually refine plastic parts from selective laser sintering (SLS) by immersing them in a dye bath. In contrast to painting, the dye penetrates into the surface making the component less sensitive to scratches.

Polishing

Polishing

Polishing improves the surfaces of metal and plastic parts. Depending on the customer requirements, we can use polishing pastes in a range of granulations for mechanical or manual processing. Polishing is used as an intermediate step for further post-processing techniques or as a final processing step.

Vibration grinding

Vibration grinding refers to mechanical wet grinding for smoothing (edge rounding, polishing) the surfaces of plastic and metal parts.

Smoothing

Smoothing

Smoothing is a method for smoothing the surfaces of plastic parts (primarily SLS) by etching with acid.

Finishing

The term finishing is used to summarize a range of post-processing activities. These include priming, filling, grinding, preparing ready for painting, deburring, etc. They are generally used as the basis for further post-processing, such as metal coating, etc.
Finishing
Assembly

Assembly

At the customer's request, we can professionally assemble single parts, e.g. by inserting threaded bushes, by screw mounting, adhering, or by welding plastic parts, etc.

Painting

One or two-component varnish is applied to a primed surface with a selection of different gloss levels (matte, glossy). The surface quality ranges from smooth to structured; additives may be added for more structure, such as grit particles or fibres. Color or clear varnish applies a coat to the surface of the component.
Painting
Vaporing

Vaporing

A surface finish that gives components a metallic look, but which does not equal the durability and electrical/mechanical properties of metal coating. Possible coating metals are aluminum and chrome.

Turning and milling

Turning and milling is a standard post-processing activity in 3D printing. This should not be confused with our service for cutting plastic parts from a solid part, which is a manufacturing rather than a post-processing activity. Turning and milling can be assigned separately for special purposes.
