Solvay has added three medical grade filaments for additive manufacturing (AM) in the healthcare industry. A KetaSpire polyetheretherketone (PEEK) filament (NT1 HC) and a 10 percent carbon fiber reinforced PEEK filament (CF10 HC), together with a Radel polyphenylsulfone (PPSU) filament are the company’s first medical-grade AM filaments for limited contact applications, meaning less than 24 hours of bodily fluid/tissue contact.

According to Jeff Hrivnak, global business manager for healthcare, the filaments are useful for a range of healthcare applications including patient-specific cutting guides for surgery and for complex components in single-use and reusable medical devices.

The company’s PEEK filaments are designed to enable fusion of printed layers, part density and part strength, including along the Z axis. The PPSU filaments are also designed to provide fusion of printed layers in addition to transparency, elongation and toughness.
