Printing Problems with PVA

Recommended Posts

Hello, I am just starting printing something with PVA, but always with failure. According to this old thread https://ultimaker.com/en/community/3458-printing-with-pva, I set almost the same parameters. But still doesn't work.

There are mainly two issues that bother me.

1. it seems that PVA is difficult to stick on the plate, even if with glue (the printer I use is ultimaker 2, with glass plate). I set the temperature from 60 to 90 degree celcius, but none of them could let PVA stick on the plate. The print temperature was set as suggested in the previous thread, at 206 degree celcius, and other settings were also followed as the thread mentioned. Is there something wrong that can explain why my PVA not sticking on the plate?

2. the second issue was that the nozzle stop extruding PVA after printing for a while, this really confused me, has anyone an idea about that?

Thank you guys in advance!

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
