Additive Manufacturing: First High-Purity PVDF 3D Printing Filament

What appears to be the first high-purity PVDF filament for 3D printing of prototypes and small production runs is newly available from Nile Polymers, Centerville, Utah. This innovative processor specializes in providing fluoropolymer products used in the chemical, biopharma and semiconductor industries. All based on Kynar PVDF from Arkema, King of Prussia, Penn., the company’s products include Strong-Ty cable ties, Purisan mixers, and Fluorinar 3D printing filaments. Only limited by print bed size, Fluorinar-C can be printed by FFS/FDM processes and without dimensional warping. 

Says president and founder Howard Fisher, “With more than 50 years of industrial use, Kynar PVDF continues to be recognized for its excellent chemical resistance, UV and ionizing resistance, non-flammability and high-temperature performance. With our family of products, Nile Polymers builds upon this product Kynar PVDF legacy.”

This newest addition to the Fluorinar portfolio—Fluorinar-C copolymer filament is designed for large parts. Says Arkema sales engineer Gene Alpin, “This new filament stays secured to the build plate during printing and comes with sll the certifications that is expected with Kynar PVDF, such as USP Class VI, NSF 51/61, and FDA certifications. This is the first  warp-resistant material to offer these certifications.” He sees it primarily for use of prototypes and small production runs of parts such as as clamps, fittings, and vessel components used in several single-use biopharma applications.

Fluorinar-C is available in 1000 g spools with either 1.75 mm or 2.85 mm diameter with a +/- 0.05 mm tolerance.  Nile Polymers is offering a 5-meter sample of either size filament to those interested in trialing Fluorinar-C.
