The “hot casting” process is carried out by us as a two-stage moulding process using additive manufacturing technologies.

Based on the actual CAD file, a multi-part casting mould is first designed. The main focus here is on an effective casting process as well as the simplest and most gentle demoulding possible.

In the first stage, the mould is manufactured with flexible materials (similar to silicone) using the stereolithography process. The result is a high quality elastic mould.

Then follows the second stage, the casting. A wax-ceramic mixture is heated to 60-90°C and poured into the preheated mould. Since the process takes place under vacuum, air inclusions are avoided.

The component created by this process is separated from the mould after it has completely solidified and then debound and fired to give it its final properties.

The great advantage of the process is the high quality of the cast components. The surface of the mould is reproduced almost perfectly with a roughness of Ra < 2 pm.


Very good surface quality (Ra < 2pm) Especially suitable for small series, as the mould can be used several times Wide range of ceramic materials can be processed


Depending on the geometry of the building, the mould construction and demoulding can be complex Slightly longer production time than other AM processes due to the two steps
