Water stuck in parts during immersion for PVA deserving.

Posted · Water stuck in parts during immersion for PVA deserving.

Hello, I’m new to the forum/ultimaker community. I work in CNC manufacturing so I have some experience although not completely related. So here is my question

when I print with PLA and PVA its awesome. the supports dissolve in water and no frustrating deburring or breaking of supports. only problem is when it is submerged in water over night. lots of my parts tend to get water stuck in them through the small openings (3d printing is not usually 100% air tight). So now all the supports are gone but now I got water stuck inside the print. and it’s kind of annoying. Has anyone had this problem and what do you guys do to solve it? I am thinking about drilling a weep hole and making another hole on top, then using compressed air to force it out.

    I just take my printed objects and put them on a paper towel or three and they are dry in a day or two. I guess it would depend on how fast you need a part dried. I am usually not in that much of a hurry as I am not in a production environment.

    Even if the print was 'air tight', it could still leak water inside if there is a strand of PVA that got dragged across the surface during printing. It would then dissolve and leave a tiny hole whilst also wicking in the water.

        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.
