Binder jetting in the open material system.
The manufacturer's InnoventX system Desktop Metal offers extensive opportunities for research and development of new metal alloys with its open system. In addition to metals, the system also enables 3D printing with ceramics and sand. To adjust the required green part strength, it is also possible to develop suitable binders for the alloys used.
The InnoventX system is based on the binder jetting process and has been expanded to include the advanced Triple ACT technology, which doses, distributes and compresses the alloy used in the printing process. In combination with precise parameter control, complex geometries with a high level of detail and density can be produced with repeat accuracy.
In the binder jetting process, a binder is applied to a layer of loose powder via several thousand nozzles according to the component cross-section. The system also features industrial piezoelectric print heads and the patented Triple ACT compaction technology, which dispenses, evenly distributes and compacts ultra-fine powders with strict parameter controls.
Once assembly is complete, the build box is removed and placed in a powder station for coarse and fine de-powdering using an air picker. A built-in powder recycling system with powder sieving removes loose powder from the parts and recovers it.
After depowdering, the components are sintered in a furnace at temperatures of up to 1400 °C. At temperatures close to the melting point, the binder escapes from the component and the molecular chains fuse together, allowing the desired mechanical properties to be achieved.
The compact construction volume processes small powder batches and was therefore designed for material development. The system also offers safety functions such as dust control.
The system was designed to switch between different materials, including more than two dozen metal, ceramic and composite materials as well as different binders.
The patented Triple ACT doses, distributes and compacts powder with precision to deliver industry-leading part density.
The open material system of the Innovent X makes it possible to qualify the company's own materials for the binder jetting process or to develop specific alloys.
In accordance with the industry standard, stainless steels such as 17-4PH, 304L and 316L as well as M2 tool steel and Inconel718 can be processed with process stability. Other metals are currently under development.
Successfully qualified ceramics include, for example, silicon carbide or alumina.
The open platform makes it possible to choose between different binders such as CleanFuse, AquaFuse, FluidFuse and PhenolFuse, which offer unique advantages depending on the material.
