What is PVB

PVB (polyvinyl butyral) is the plastic of the film between the two glass layers of a windshield. As a filament, its appeal is that it dissolves in isopropyl alcohol: exposed to its vapors, the surface melts slightly and the layers disappear, leaving a smooth, glossy part. The 3 datasheets analyzed print it with the nozzle at 205–225 °C.

How to smooth PVB with isopropyl alcohol

  1. Print the part with enough wall thickness: smoothing consumes a thin layer of material.
  2. Place it in a closed container with atomized isopropyl alcohol or in a vapor-smoothing device.
  3. Let it work for just the right amount of time; too long rounds off details and edges.
  4. Take it out and let the alcohol evaporate until the surface hardens.

It is an alternative to smoothing ABS with acetone, with a solvent that is easier to get and to handle, though just as flammable: ventilate and work away from any flame.

FAQ

Frequently asked questions about PVB filament

Does PVB become transparent after smoothing?

Natural versions end up very translucent and glossy. Full transparency depends on printing with complete infill and no air between lines.
