Is this a sign of moist PVA filament?

Posted · Is this a sign of moist PVA filament?

Hi everyone, 

 

I've just started working with PVA support and I'm wondering whether the fuzziness around the edges of the print and the little tiny flecks that cover the bed are a sign of moist PVA? It doesn't seem to affect the quality of the actual printed part, so then is this just normal? 

 

I looked for images online of PVA supported prints and they look much cleaner than this but I wasn't sure whether someone had tidied them up just for the photo. 

 

Any information would be appreciated. 

 

Best, 

 

Chris

    I think no, it is normal for PVA that is looks not so pretty and that you have some pieces around on the glass.

     

    With PVA which has absorbed too much moisture, you are usually not able to print. It will stop extruding and clogging your nozzle.

    PLA is so wonderful that when one switches to another material, one is surprised at how crappy it is.

     

    PLA sticks to itself really well when liquid.  Like mucus. Like snot. Like a liquid rubber band.

     

    PVA does not.  It's more like concrete.  Chunks of PVA are often separating and falling (while still liquid).

        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
