The motion plastics specialist Igus has expanded its additive manufacturing portfolio with the introduction of Iglidur i190PF, a new PTFE-free filament designed to deliver exceptional wear resistance and mechanical performance. The material achieves a coefficient of wear up to 100 times better than standard 3D printing plastics, marking a significant advancement for engineers requiring durable, low-friction components.

Building on its extensive range of over 50 injection-moulding materials, Igus continues to bridge the gap between traditional manufacturing and 3D printing. With Iglidur i190PF, the company brings the proven performance of its injection-moulded plain bearing materials into filament form, enabling the cost-effective production of prototypes, complex geometries, and small batches.

The new filament is a PTFE‑free evolution of Iglidur W300 and aligns with increasing industry focus on PFAS-free alternatives. “We wanted to offer PTFE-free materials across all 3D printing technologies in response to growing regulatory discussions,” said Jonas Burk, Head of Additive Manufacturing at Igus. Iglidur i190PF complements existing PTFE‑free resin and SLS materials, expanding design flexibility.

The Iglidur i190PF filament is specified with a flexural strength of 80 MPa and is designed for abrasion-resistant, maintenance-free and lubrication-free components. According to the manufacturer, parts produced with the material can be used at temperatures of up to 90 °C and are also suitable for multi-material designs due to their bonding properties.

The material was tested in the company’s 5,500 m² laboratory. In a pin-on-disk test against stainless steel, Iglidur i190PF reportedly achieved a wear rate 100 times lower than PETG. Although the filament is PTFE-free, it is said to offer performance comparable to the established Iglidur i190 material.

Iglidur i190PF is available as a filament for use on standard enclosed FDM printers. It can also be ordered through the company’s 3D printing service, where customers upload component designs and receive finished parts.
