Purple PVB 1.75mm Smoothable Filament

Realize stunning results with PVB 3D printer filament. PVB (PolyVinyl Butyral) is a newer type of filament that has some unique and attractive properties. PVB has poor layer bonding before post-processing but its mechanical properties exceed those of PLA. It does not require a heated bed (but is recommended). PVB can be 3D printed at relatively low temperatures (around 220°C). This means that it can be used with almost all 3D printers on the market, including devices with a Bowden setup.

Perfectly smoothed surface after treatment with IPA.

PVB filament is highly hygroscopic therefore it should be stored in airproof container. To assure best possible print quality filament should be dried (60 °C, 4-8 h) before printing. The product has a distinct odour and a ventilated area is recommended.

Print Temp 210-220ºC
Hot bed 65-80ºC (recommended)
Surface Glue Stick, PEI or Kapton Tape

PVB is the first type of filament designed for easy post-processing and cleaning up layer lines. Always get a very smooth 3D printing surface. Smoothing is best done with IPA (isopropanol). Spray IPA on or dip the entire 3D print in it, depending on the effect you want to achieve. Once this is done, you will have a completely smooth surface. Buy your PVB 3D printer filament now.
