I have some 1.75mm PVDF filament I recently extruded with my filastruder for sale in 100g, 250g, and 500g quantities for $50, $100, and $150 respectively, with freee shipping to the continental U.S. PVDF is a part of the teflon family of plastics and has excellent chemical resistance to many solvents, alcohols, acids, and dilute bases. From Arkema's website:
Kynar® fluoropolymers are specified by end-users across the world for their outstanding combination of properties:
Outstanding resistance to sunlight/UV exposure
Tremendous chemical resistance to a wide range of aggressive chemicals
Radiation resistance
Excellent burn characteristics / flame and smoke properties
Easy processing on industry-standard equipment and easy post-processing such as welding and fabrication
Extremely high purity for the most demanding applications
Extremely high electrochemical stability
Excellent abrasion resistance
High temperature rating: RTI 150º C
I'm still dialing in the printing parameters for my 1.0 mm nozzle machine, but I've had good luck with 250-260°C extruder temps, and a bed temp of 90°C. Disappearing purple elmers glue stick is a must to keep PVDF attached to the bed, it has very low surface energy and friction. If you have any questions or would like to purchase please let me know, thanks!
