Sustainability of our 3D technology

Exentis 3D technology makes manufacturing processes more sustainable and viable for the future.

For the benefit of our 3D community members.

The focus of our cold-printing process is on maximum material and energy efficiency in the manufacturing process. Our specific goal involves trying to use nothing but sustainable raw materials, having full recyclability and preventing transport operations by having local production.

Exentis 3D technology is fundamentally different from traditional manufacturing technologies like milling, grinding or punching, where up to 90% of the starting material is removed to achieve the desired component geometry. There is no material waste, which needs to be disposed of, when using 3D screen printing.

Our 3D technology therefore enables a material and energy-efficient production of components. The system only processes the amount of material that the respective component requires.

Our technology also offers significant advantages compared to other additive 3D printing processes. Exentis 3D screen printing does not require any supporting powder or structures like other 3D printing processes, which then have to be elaborately removed after the printing process and prepared again before they can be reused.

Our 3D technology does not require the use of environmentally harmful solvents or UV-curing polyurethanes, acrylates or epoxides.

The main components used for paste production are biocompatible, do not pollute water supplies, they are non-toxic and are not classified as hazardous substances.

All the raw materials are based on standardized products, which can be produced both using the petrochemical cycle but also as part of a hydrogen-based circular economy in the future.

Unused pastes can be reprocessed without any problems. The recycled metal or ceramic powders can be fully reused for new pastes. There is no need for any expensive disposal operations.

The cold printing process, which is used for our 3D technology, also sets new standards. All the materials, including metal or ceramic pastes, are processed at room temperature. In the case of polymers, but particularly with biomaterials and in tablet production, the material features would otherwise be destroyed, and active cell cultures would not be able to survive.

It is also important to emphasize the significantly lower energy consumption of our 3D technology compared to laser-based processes, which require much larger quantities of energy and special precautions for the operating personnel.

Using our 3D production systems directly at our 3D community members’ facilities enables them to manufacture on-site, completely detached from any potential interruptions to international supply chains.

Because we manufacture our screens within 24 hours, 3D community members can tailor the component quantities and geometries that they produce exactly to the needs of their own clients. There is no “production to create stockpiles”.

Compared to traditional manufacturing technologies like injection molding, our 3D technology offers the opportunity to complete a wide range of product variations in a fast and flexible manner and at attractive costs for the very first time.

Overall, this minimizes inventories and storage costs and reduces international transport operations.
