The company D3-AM has introduced a new 3D printing process for technical ceramics. Micro-particle jetting (MPJ) involves printing highly concentrated suspensions with virtually any particle size. According to D3-AM, this enables the production of high-quality, dense components from materials such as zirconia, alumina and silicon carbide.
The technology is based on inkjet technology, in which D3-AM parent Durst Group is a world leader. Thanks to a specially developed nozzle, suspensions with large particles and a high solids content can also be printed. According to D3-AM, the targeted droplet generation leads to complex component geometries in industrial quality.
The advantage over conventional binder jetting, it says, is the ability to sinter components directly, without subsequent infiltration or post-processing. According to D3-AM, this makes technical ceramic components possible that cannot be produced using other processes.
At Formnext 2023, D3-AM plans to showcase the new micro-particle jetting and the associated LABII printing platform. Printed components made of aluminum oxide and sintered silicon carbide will be demonstrated. In the long term, the company sees great potential for additive manufacturing of sophisticated ceramic components.
