3D PRINTING

Housing for acoustic filters
Our 3D print Admaflex technology enables producing ceramic prototypes and small series without tooling, saving time and cost on tool manufacturing. It also provides the opportunity to print complex geometries, with the flexibility to make alterations as you go. The demonstrated product is a high class acoustic in-ears e.g. for musicians. The combination of overall quantity, shape, aesthetics and acoustic requirements resulted in a perfect business case for 3D ceramic printing.

3D PRINTING / MACHINING

QC caliber
Formatec was challenged to make this part in low volume with high complexity and for some dimensions tight tolerances. A print plus machine approach was selected in order to deliver a total of ten products. The majority of the shape was a result of the printing process. The required dimensions for the twelve holes and two holes in the pillars were not achieved during printing and therefore post machined in the sintered phase. This approach helped to save money for the customer because expensive machining steps were only used to obtain the tight tolerances and not for shaping.

PREFORM / GREEN MACHINING

Key fob
This part was produced through green machining, because of the size which is not ideal for 3D printing. A preform was produced with a simple mould, in the end to create a near nett shape. By applying our in-house developed process FormShape; 5-ax milling with special coated tools, debinding and sintering. In the end, the product as been delivered in a high gloss surface finishing, which was very well received by the customer.

MOULDING

Driving & Crown gear
Ceramic Injection Moulding (CIM) can be compared to the reproducibility of plastic injection moudling, delivering quality for an economical price. The gear set was produced by moulding, debinding, sintering and tumble finishing. Tolerances kept throughout this process on this geometry are +/- 0.01mm or smaller.

MOULDING / MACHINING / GRINDING

Sensor housing
Ceramic Injection Moulding (CIM) can be compared to the reproducibility of plastic injection moudling, delivering quality for an economical price. For some parts we use the moulded geometry as starting point. After that, we can add machining steps for various reasons. Examples of these are shown in the drawing below;
Due to the modest numbers per year Formatec Ceramics has chosen to reduce the mould complexity by green machine
the slots and undercuts. A final dimensions is tightly toleranced and will be grinded.
