PVDF Filament

Polyvinylidene Fluoride / Kynar

F
Also known as:Polyvinylidene FluorideKynar
Family:PVDF

Why Use PVDF?

  • Prints like PETG but tougher; very durable; hydrophobic (no drying)
  • Extremely chemically resistant

Things to Consider

  • If overheated, decomposes into highly toxic chemicals (including hydrogen cyanide and hydrofluoric acid)

Safety & Ventilation

  • Print PVDF in a well ventilated area. Higher-temperature materials like this can release fumes and fine particles while printing. An enclosure improves print quality and helps contain fumes, but it is not a substitute for fresh air, so vent the enclosure or run an air filter and avoid an unventilated occupied room.
  • Never exceed the recommended temperature. If overheated, PVDF can release hydrogen fluoride and other toxic gases, so strong ventilation is essential.
