March 19, 2025. AMAREA Technology GmbH was founded just two years ago as a spin-off of Fraunhofer IKTS and is now commercializing the Multi Material Jetting (MMJ) technology developed at IKTS. The new MMJ ProX series multi-material 3D printer from AMAREA makes it possible to print up to six different materials in parallel in one component.

This makes it possible to produce miniaturized and large-format complex components with tailored combinations of properties that were previously impossible or only possible with considerable additional effort. This opens up innovation potential for applications in aerospace, electronics, mechanical engineering, energy and medical technology, but also in additive manufacturing for the jewelry and watchmaking industries.
In MMJ, particle-filled, thermoplastic printing materials are built up precisely and drop by drop, layer by layer, to form highly complex, functionalized components and assemblies. The droplets are only placed and fused where material is needed – this saves material and reduces post-processing steps. Dr. Uwe Scheithauer, Group Manager Additive and Hybrid Manufacturing at Fraunhofer IKTS, emphasizes: “We can offer our customers very flexible and particularly resource-efficient manufacturing processes for multi-materials, as we can work without tools and significantly reduce waste.”
The manufacturing system has a modular structure and, like the thermoplastic printing materials, is optimally aligned to customer requirements. As a result, the mechanical (hardness and flexibility), functional (electrical conductivity vs. insulation) and thermal properties as well as the chemical resistance of the components can be precisely adjusted. Different aesthetic and haptic properties can also be combined.
With the delivery of the MMJ ProX printer to Fraunhofer IKTS, AMAREA Technology has reached another milestone in the commercialization of Multi Material Jetting (MMJ) technology. The partners convincingly demonstrate how applied research can be turned into market-ready high technology. “We are delighted that Fraunhofer IKTS is one of the first customers to use our system for the development of innovative products, thereby helping to expand the market for multi-material applications,” says Steven Weingarten, developer of the MMJ technology and co-managing partner of AMAREA Technology GmbH.
With the new printer, the IKTS team is now testing the extended production possibilities for complex ceramic multi-material components and wants to use them to open up further fields of application for ceramic 3D printing.
