In 3D printing Evonik silica provide free flow, anti-caking and electrostatic charge control for SLS and SLA as well as viscosity control over jetting systems and density control in power packing.

Technology with huge potential: Silica from Evonik in 3D printing


The possibilities of 3D printing seem all but infinite. Silica from Evonik are bespoke particles for your individual application. Be it as flow additives, reinforcing materials or to control viscosity, they help you get the best out of your products and process.


3D printing is one of the most exciting technologies around at the moment, allowing efficient production of individual products. Silica from Evonik support you with your specific requirements. 3D printing offers particularly great potential in the automotive industry, aerospace, and medical technology. The technology is already established in mechanical engineering, where it enables even complex components to be produced in a way that saves both material and resources. 
Additive manufacturing – the technical term for 3D printing – denotes all processes in which material is applied layer by layer to produce an object. What makes 3D printing special is the fact that there are almost no limits on the material or the printing process. 

Silica help to optimize both the process conditions and the quality and properties of the printed items. The AEROSIL® fumed silica, AEROXIDE® fumed metal oxides and their homogeneous dispersions are hugely versatile, serving as flow additives for powders, as reinforcing materials for polymer systems or to reduce the electrostatic charge of a material. We thus have the product with the perfect recipe for your needs. With more than 70 years of experience in particle development, we are here to support you in your unique 3D printed products.
