PVDF [Polyvinylidene fluoride] is a high-performance polymer offers exceptional thermal and chemical resistance for industrial-grade printing, commonly used in the chemical, semiconductor, medical and defence industries. PVDF is also used as a binder component for the carbon electrode in super capacitors and for other electrochemical applications.
Rated for uses up to 150°C - this filament can be used in demanding applications and under the most extreme conditions. 3DXSTAT™ PVDF is resistant to most chemicals and solvents making it a great fit for applications that will be exposed to harsh environments.
We start with premium Arkema Kynar® PVDF resin and then compound according to a proprietary formulation of speciality carbon additives, giving you a filament with excellent printing characteristics and consistent ESD properties.
Product attributes include:
- High continuous use temperature - up to 150°C
- Excellent resistance to a broad range of chemicals, such as automotive fluids (oil, gas, lubricants), fully halogenated hydrocarbons, alcohols, acids and bases
- Non-hygroscopic - does not absorb moisture - no drying of filament or special storage is needed
- ESD-Safe with a 10^6 to 10^9 ohm surface resistivity on 3DP sample using concentric ring test method.
- Inherently UV-resistant (H-F bonds are very stable in exterior applications)
- Very good abrasion resistance - similar to Nylon and UHMW-PE for high-wear applications
- Low smoke and flame characteristics (base resin is rated V-0)
- Long-term hydrolytic stability
- Resistant to nuclear radiation

Surface conductivity as a function of extruder temperature:
The surface resistance of the printed ESD-safe part will vary depending on the printer's extruder temperature. For example, if your testing indicates the part is too insulative, then increasing the extruder temperature will result in improved conductivity. Therefore, the surface resistance can be 'dialed-in' by adjusting the extruder temperature up or down depending on the reading you receive on your part.
Recommended Print Conditions:
- Extruder Temp: 250-270°C
- Bed Temp: 90 - 110°C
- Bed Prep: PVA-based adhesive, Hairspray, Lightly sanded FR4 or Perf board.
- Other: No or light cooling fan; print speeds of 40-60mm/s as a good starting point
- Drying: PVDF does not absorb moisture and does not require drying.
Safety note: This polymer starts to degrade at temps above 290°C. Please keep your extruder temperature below this point to avoid degradation, off-gassing, and mechanical property loss.

ESD PVDF - Difficult to print, amazing properties
Of all 3dxstat products, the PLA and the PVDF are the only things that passed our rigorous ESD Standards. We have a 3d45 Dremel printer and this material is insanely difficult to print. We had the most luck with a 10% cooling fan, 260C extruder, 100C bed (max temp for our printer), .3mm layer, and a 0.3mm nozzle offset, 100% flowrate Once you finally are able to get something printed, it is amazing. Works great in our Wave machine.
I have had a difficult time trying to get this material to print well, and there isnt much out there on the internet about it. From what i can tell it behaves a lot like PETG; ive been troubleshooting it as if it is. Im using an enclosed CR-10S and have good luck printing on glass with purple glue stick. The settings that have worked best for me are 110C bed, 260C(my printers max temp) first layer and 250C hotend temp. I use 100% flow rate for the first layer and 98% after that, otherwise it makes a mess of the nozzle. 0.2mm layer height. 15mm/s first layer and 30mm/s print speed. No matter what i do i still get zits and oozing in a lot of places, but im using a bowden setup which probably doesn't help. Apart from difficulty printing this material is awesome. its got the slightest flex to it but holy **** is it durable. You couldn't brake this stuff with a hammer. I'm currently using it to create tooling for use inside a selective soldering machine and have used it continuously at temps over 120C, and so far so good.
