FEP Filament

Availability: On backorder


Experimental Filament not always in stock, but you can order.

FEP ( Fluorinated Ethylene Propylene)

PTFE and FEP are similar in their material properties. The main difference between PTFE and FEP lies in the maximum operating temperature and the colour. PTFE is milky/white and FEP is clear transparent.


• Lower melting temperature than PTFE
• More flexible than PTFE
• Transparent/clear
• Low dielectric constant (insulating)
• Chemically inert
• Very low co-efficient of friction
• Antistick properties
• UV resistant (does not age)
• Not hygroscopic (water absorption <0.01%)
• FDA approved
• Working temperature from -200°C to +205°C

FEP is more difficult to print than our Fluorinar-PVDF. 
You need high temperatures: 320-380ºC and heated bed ± 160ºC and closed printer.
Ventilation is very important

Nozzle temperatuur 320ºC - 380ºC
heated bed ±160ºC
speed 20-25mm/s
layer 0.2mm
bed glas
density 2.16gr/cm3
melting point 258ºC
tensile strenth at break 30 MPa
elongation at break 350%
UL rating V0

Alternative for FEP:
Fluorinar-PVDF-C easy to print (±250ºC) on any 3d printer with a heated bed(100ºC); no warping.
