High-performance ceramics from 3D printing and CNC precision processing

Awalux AG develops and manufactures sophisticated technical ceramic components for industry and medicine. The combination of additive manufacturing, in-house material development and precise CNC processing in a pre-sintered and sintered state creates tailor-made solutions with maximum performance.

Material expertise as a foundation

Technical ceramics such as zirconium oxide ZrO2 and aluminum oxide Al₂O3 offer exceptional properties. These include extreme wear resistance, high temperature and corrosion resistance, electrical insulation and biocompatibility. Zirconium oxide in particular is established in the medical environment, as it combines high mechanical strength with excellent tissue compatibility.

A key competitive advantage of awalux lies in its own production of resin for ceramic 3D printing. The dispersion of ceramic powder and photoreactive binder is formulated internally and continuously developed. As a result, mixing ratios of zirconium oxide and aluminum oxide can be adjusted in a targeted manner. Mechanical characteristics, shrinkage behavior, sinter density or even aesthetic properties can be optimized for specific applications.

This vertical integration from raw material to resin formulation to the finished precision component ensures maximum process control and reproducible material quality.

Additive manufacturing for development and small batches

In 3D printing, awalux uses the stereolithography process. A UV laser solidifies the specially developed ceramic resin layer by layer to form a greenfinch. After the pressure sequence, debinding and sintering process, in which the component acquires its final density and mechanical strength.

Additive manufacturing enables rapid prototyping without tool costs, short development cycles with several iteration stages, a high degree of geometric freedom and the economical production of small series. Through targeted material optimization, awalux is able to precisely match printing parameters, shrinkage and ultimate strength. This is crucial for dimensional accuracy and functional reliability.

Medical applications with approved materials

Patient-specific tissue formers made of zirconium oxide for dental implantology, for example, are a future-oriented area of application. They are used for the controlled formation of peri-implant soft tissue during the healing phase.

Ceramic tissue formers are characterized by high biocompatibility, low bacterial adhesion, excellent mechanical stability and an aesthetically attractive white color. The zirconium oxide used is based on medically approved material and meets the regulatory requirements for dental use. In combination with 3D printing, individual geometries can be created that are precisely tailored to the implant position and anatomical situation.

CNC processing in white and final state

A central element of the manufacturing strategy is CNC processing both in the pre-sintered state as whiteplate processing and after sintering.

When white, the material is still relatively soft and can be milled efficiently. Complex contours, holes and functional geometries can be produced with reduced tool wear. The subsequent sintering and the defined shrinkage are taken into account constructively.

After sintering, high-precision finishing is carried out using CNC milling and diamond grinding as required. Sintered ceramic is extremely hard and brittle and requires specialized tools and stable process management. With modern multi-axis machining centers and precision grinding technology, tight tolerances, defined surface qualities and functional fits are reliably achieved.

The combination of whitewashing and finishing offers a high degree of flexibility while at the same time cost-effective production, in particular for complex geometries and small and medium-sized series.

Development partner right from the start

Customers provide their design data in a standard 3D format. Awalux holistically analyses feasibility, choice of materials and manufacturing strategy. Early integration into the development phase enables ceramic-friendly construction, optimized wall thicknesses, low-stress geometries and efficient use of materials.

Through targeted material blends, functionally integrated design and precise process management, components are created that compensate for their higher material costs through extended service life, reduced maintenance costs and increased performance.

Conclusion

With its own ceramic resin development, ceramic 3D printing, medically approved materials and CNC processing in white and final state, awalux offers an integrated range of expertise in high-performance ceramics. From industrial wear components to patient-specific tissue formers, awalux stands for material expertise, process reliability and precision at the highest level.
