Addigy® G8527

Engineering-grade, glass-filled PET pellet for fused granulate fabrication 3D printing.
For your tools and large-size structural components.

Cost-effective solution for tools and large size structural components

Covestro introduces Addigy® G8527, a sustainable, glass-reinforced PET material for fused granulate fabrication additive manufacturing, or pellet printing. The material is a cost-effective solution for tools and large size structural components for varied industries such as automotive and construction.

The automotive parts market and tooling industry is growing rapidly, and manufacturers need tools to be manufactured faster and more economically. Traditional manufacturing is a multi-step process, making it an expensive and time-consuming operation. The design process also often requires additional time for trial and error.

In response, Covestro has developed Addigy® G8527, a 3D printing material that is easy to print and can build parts demonstrating the required high-performance properties. The pellet material has been developed from the engineering-grade material used in high volume production.

Additive manufacturing technology can help drive down the amount of time to build tools by reducing the number of steps needed, decreasing overall cost and offering a more sustainable solution. Additive manufacturing also eliminates the need for inventory and extra resources, saving on waste.

While Covestro continues to develop these solutions, the benefits will remain the same: superb mechanical and temperature performance, ability to print on demand, plus cost and time savings.


  • Tooling, including for autoclave
  • Prototypes
  • Low volume production of end-use parts (small size production, automotive and industrial spare parts)
  • Infrastructure, like pedestrian bridges
  • Large-size solutions
