When designing complex parts for demanding applications, you want to have the best of both worlds. A material of superior quality and the design freedom offered by additive manufacturing, or 3D printing, to achieve optimal functionality.
For good reasons, PEEK may be the material of your choice, but up till now this came with a downside. Printing PEEK is far from easy, because of its high viscosity in the molten state and its semi-crystalline nature, which induces shrink upon solidification. A common reflex of process developers then is to adapt the material to the available printing technology.
