Evonik enables 3d printing for the things to come
We drive additive manufacturing along the entire value chain by offering industrial ready-to-use high-performance materials for all major polymer-based 3D-printing technologies.
Additive manufacturing is a highly promising market. 3d printing is fast, innovative—and therefore ideally suited to an industrial world where every cent and every second count. And for a number of years now expectations regarding the development of tool-less production have been correspondingly high.
Evonik is a leading manufacturer of high-performance filaments based on PEEK and bioresorbable Polymers as well as highly specialized inorganic particles suitable for 3D material extrusion.
The material in this process is a polymer filament that is supplied by a roll. A print head liquefies the material in a manner similar to a hot-melt glue gun. As a result, components are created layer by layer out of liquid polymer. A second print head adds support material, which it deposits into cavities and at overhangs, for example, because the component has to be supported in these areas during the printing process. This support material is removed after the component is finished.
Fused Filament Fabrication (FFF)
Fused Filament Fabrication (FFF) 3D printing technology meets the requirements of individual parts, while being extremely material-saving and capable of processing the high-performance polymer PEEK. Using FFF, the material is melted in filament form, a kind of plastic strand, through the printhead using high temperatures of up to 500 °C and applied in different layers to the desired component. Decisive for the component quality is the controlled solidification process of the semi-crystalline plastic.
Some methods melt or soften the material to produce material layers. Besides the deposition of single elements in the 3D structure, fast and continuous deposition of 1-dimensional structures within the 2D slayer is possible in this technology. In fused filament fabrication, also known as fused deposition modeling (FDM™), the model or part is produced by extruding small beads or streams of material that harden immediately wile cooling to form layered structures. A stream or filament of thermoplastic, a metal filament, or other (composite) material is fed into an extrusion nozzle head (3D printer extruder), which liquefies the material and turns the flow on and off. Meanwhile printers with simultaneous multi material deposition are available, also allowing support structures for complex geometries.

Evonik had already delivered the first polyamide 12 powder material for Powder Bed Fusion in 1996 setting new quality standards that currently apply to 3D printing of polymer materials.
A powder is deposited layer by layer and fused at the places where a component is to be created. Depending on the method in question, this is either done by a laser (LS) or an infrared light (Multi Jet Fusion™/MJF, High Speed Sintering/HSS). In the second variant, an inkjet printer prints a mostly black marking on the places that are to be fused. The black areas heat up faster than the unmarked areas. The finished component is then taken from the powder bed.
The specialty chemicals company is a world leader in the production of polyamide 12 powders (PA 12), which have been used in 3D printing for over 20 years. The development of the flexible high-performance powder expands Evonik’s existing product portfolio of synthetic materials for 3D printing. Evonik produces the powder materials at its largest global site, the Marl Chemical Park.
