Solvay has launched three polymer filaments for use in 3D printing.

The materials are based on the company’s KetaSpire polyetheretherketone (PEEK) and Radel polyphenylsulfone (PPSU) polymers. KetaSpire is available as a PEEK product and a 10% carbon fiber-reinforced grade. Both PEEK filaments are designed to allow improved fusion of printed layers, enable high part density and deliver improved part strength, Solvay says.

Radel PPSU reportedly offers high transparency, improved elongation and improved toughness for 3D printed parts.

Solvay also plans to develop a powder based on its NovaSpir® polyetherketoneketone (PEKK) polymer, for additive manufacturing (AM) applications in aerospace and healthcare.

 ‘Solvay’s new AM filaments signal an important convergence between additive manufacturing and specialty polymers technology, which is needed to deliver on the promise of high-end 3D printing,’ said Christophe Schramm, business manager for additive manufacturing at Solvay’s Specialty Polymers global business unit. 

Solvay has also developed a new website for its 3D printing materials at
