CONCR3DE Silicon Carbide

The CONCR3DE platform enables 3D printing of Silicon Carbide for Silicon Infiltration (SiSiC), achieving high density and precision at both lab and industrial scale.
Benefits 3D printing silicon carbide
The traditional SiSiC manufacturing method includes high-pressure molding and milling steps. Just as with any molding, this limits shape flexibility. Milling results in waste, and the hardness of the material results in high tooling costs. 3D printing overcomes these challenges. The process is fast, flexible and allows complex shapes leading to new applications, lighter components and better performance. Our 3D printing process enables you to create large parts, influence material properties and produce unique parts in a very fast manner. By recycling unused powder, the process is highly sustainable and produces zero waste. Reduced time to market and reduced material usage result in 3D printing SiSiC being highly cost-effective, and feasible for both small and large production runs.
Powder & binder options
Our 3D printer range supports different types of binder and powder to print green parts that, after debinding with heat, become brown parts ready for silicon infiltration. Our Plug-and-Play CONCR3DE Silicon Carbide A combines an aqueous binder with our in-house SiC powder. This material is easy and safe to handle and offers a green bending strength of 8 Mpa. Additional carbon can be added by mixing carbon black in the powder or resin infiltration after printing. Your process, however, may require a different binder type. This is also possible. Our printers support both solvent and phenolic binders. In this case, the customer typically supplies the powder. Our team is ready to work with you and create the optimal solution for your production process.
Integral process
The exact post-processing steps depend on the required infiltrated material properties and the specific combination of powder and binder used. CONCR3DE understands the necessary steps, and fully supports you in designing the most efficient production process fitting with your existing equipment. If additional post-processing equipment is required, our team and partners support you in ensuring the optimal fit with your needs, your infrastructure and your way of working. Typically, the process of 3D printing SiSiC involves the following steps:
