Parts producer Weerg continues to build extensive expertise in materials development. Following the release of the Extreme™ Carbon Fiber+PA12, the company unveils PEEK, an organic thermoplastic polymer designed for FDM printing.
The new filament is part of the polyetheretherketone family and is characterized by its extreme light weight while providing a tensile strength (UTS) of up to 89 MPa. Due to its high mechanical strength and low density, it is a good candidate for replacing the main non-ferrous metal alloys.
In addition, Weerg develops a flame retardant (tested to UL94 V0 class) material which can withstand substances such as oils, greases and hydrocarbons, ensuring excellent thermal performance. In fact, it can withstand continuous use at temperatures up to 145°C and up to 250°C if heat-treated. Other advantages include maximum resistance to vibrations, even the most intense ones, and very low moisture absorption, characteristics that further extend its fields of application.
The PEEK tested and used by Weerg is amorphous, with a very particular amber color, to ensure greater ductility and impact resistance. Weerg’s PEEK products are therefore also suitable for use in severe conditions and harsh environments, such as in the aerospace sector, where it can be used for the manufacture of structural components, covers and insulation, or in the medical sector, as it is considered an advanced biomaterial for the manufacture of implants and prostheses.
“[…] We invest significant resources in the development of materials with special characteristics that can be used for specific industrial applications, constantly expanding our offer”. Matteo Rigamonti, founder of Weerg. Explains.
As a reminder, Weerg combines in its 3D printing department, the largest European installation of HP Multi Jet Fusion 5210 industrial printers, 12 units of which are flanked by the same number of Lherr 4000 (MSLA +4KSPER) stereolithographic printers for resins and 6 additive manufacturing systems with FDM technology. For CNC machining, Weerg has 10 Hermle C42U 5-axis continuous machines divided into two batteries, each of them completely automatized using anthropomorphic robots and loading/unloading stations that communicate directly with the internal management system, as well as 2 fully automatized Mazak Integrex Multitasking i-200 lathes. Cutting-edge solutions for all types of machining, capable of guaranteeing a perfect combination of automation and Industry 4.0 processes.
