Sustainability of our 3D technology
The cold printing process in use focuses on meeting highest levels of material efficiency in the manufacturing process, employing sustainable and recyclable raw materials, low energy consumption and the prevention of transport routes by using local production.
Exentis 3D technology is fundamentally different from traditional manufacturing technologies such as milling, grinding or punching, where up to 90% of the starting material is removed in order to obtain the desired part geometry. There is no material waste, which needs to be disposed of, when using Exentis 3D screen printing.
Our 3D technology thus enables a material-efficient build-up of industrial parts. Only the exact amount of material that makes up the respective part is processed. This reduces the use of materials to an absolute minimum.
Our technology also offers decisive advantages compared to other additive 3D printing processes. No support powders or support structures are required that would have to be laboriously removed after the printing process and then to be reprocessed before further use.
The main components used to make our pastes are biologically compatible, non-hazardous to water, non-toxic and not classified as hazardous substances. Exentis 3D technology does not require the use of environmentally harmful solvents.
All the raw materials are based on standardized products that can be produced both on the petrochemical route and, in the future, in a hydrogen-based circular economy.
Any pastes that are not used can be easily repro- cessed. The recycled, valuable metal or ceramic powders can be fully reused for new pastes. There is no need for any expensive disposal procedures.
The resource-saving cold printing process used as part of the Exentis 3D technology sets a very high standard. All the materials are processed at room temperature, even metal or ceramic pastes. Otherwise, the material properties would be destroyed in polymers, but also in bio-materials and when producing tablets, and active cell cultures would not be able to survive.
It is important to emphasize the significantly lower energy consumption of our 3D technology when compared to laser-based processes which require much more energy and special caution on the part of the operating personnel.
A decentralized deployment of our 3D production systems directly at 3D community members’ facilities enables them to manufacture on-site, completely independent of any disruptions to international supply chains.
As we are able to manufacture our screens within 24 hours, 3D community members can exactly tailor the quantities and geometries of their parts to the needs of their own customers. There is no need for “production for stockpiles”.
For the first time, our 3D technology thus offers the possibility of realizing a wide range of product variations promptly, flexibly and at attractive costs compared to conventional manufacturing processes such as injection molding.
Overall, this minimizes warehouse stocks and related storage costs and avoids international transport operations.
