Which materials do you offer?

For the additive manufacturing of ceramic components we use alumina and zirconium oxide.

What is the maximum size of a component?

The available  effective construction volume is: 81.9 x 51.4 x 250 mm for alumina and 75.3 x 47.2 x 240 mm for zirconium oxide. These values apply less the thermal shrinkage.

What does technical ceramics mean and where are they applied?

Technical ceramics or equally high-quality ceramics / engineering ceramics are mainly applied in the industrial area. They are characterised by qualities like, for example: very high temperature, wear, chemical resistance and many more.

Where do I find the prices for components of additive manufacturing?

Due to the individual shape of every work piece there is no generalised price list for components in additive manufacturing. Please use our contact form for your query.

What do you need for creating an offer?

For a general feasibility check and an offer preparation in addition to your contact data we need the desired quantity and 3D CAD data, preferably in STEP format (alternatively .STL). Moreover, a technical drawing is an advantage for a detailed assessment.

Are various colours possible?

The materials to be produced by us (alumina and zirconium oxide) are exclusively available in white colour.

How solid can the components be?

Due to the necessary debinding proceeding a thermal decomposition and degassing of the polymer, the wall thickness depending on the material shall not exceed 3 mm (zirconium oxide) resp. 6 mm (alumina). Higher wall thicknesses significantly increase the probability of cracking. By design adaptations (intrusions and penetrations, depressions) thicker walls can be realised as well.

How thin can the wall of a ceramic component be at most?

In the additive manufacturing thin vertically freestanding walls are particularly risky. Here the lack of stiffness plays a role both in printing and in thermal proceeding. For the construction we recommend the following minimum thicknesses: from approx. 0.15 mm a height of 2 mm is possible. For mutually supporting walls (e.g. cross profile) the height is largely not limited.

How precisely can the components be manufactured?

The accuracy in processing is mainly determined by the shrinkage in the thermal process. The following tolerances apply: ± 1 % of the linear measure but maximum ± 0.1 mm. Depending on the geometry higher accuracy can be achieved by iterative approximation.

Is a post-processing of the components possible?

In general it is possible to work technical ceramics by special tools. However, we do not offer a post-processing of components made in additive manufacturing.

How long is the delivery time for components made of technical ceramics in additive manufacturing?

Due to the subsequent processes the estimated delivery time is 4 weeks approx., depending on the order situation. The exact delivery date will be announced after receipt of order.
