METAL BINDER JETTING (MBJ)
From Detailed Features to Massive Structures
The longstanding partnership between GKN Additive (Forecast 3D) and HP has led to the industrialization of binder additive manufacturing (AM) for serial production.
Unlike other AM technologies, Metal Binder Jetting is not limited to prototyping or small-batch production. As a sinter-based process, the finished parts have characteristics suitable for real-world applications. The sample parts already correspond almost completely to the finished series parts, which means that the process enables scalable 3D metal printing with exact reproduction of the most complex shapes — not only on an industrial scale, but also within the desired time and cost framework.
Sinter-based AM requires enormous expert knowledge, and this is where GKN Additive's particular know-how lies. Thanks to this expertise, the company — which is headquartered in Bonn, Germany, with production sites in the United States, Germany, and China — is able to identify potential problems in advance and knows how to prevent them from occurring in the first place.
We offer all steps of the industrial AM product development cycle, from product design to 3D printing, to sintering and finishing.
- Leverage our extensive know-how in the sintering process and in metal injection molding production for 20+ years.
- Profit from our extensive experience in series production.
- Take advantage of our “Design-for-Binder” consulting services, which include product engineering and a focus on optimization potential so that we can spark new ideas and realize our customers’ dream designs.
