Porosity in center of print on UMS3

Posted · Porosity in center of print on UMS3

Hi everyone,

 

I've had some issues with some underextrusion in the center of my parts (on a UMS3).  This appears to happen after the first layer, and it is almost always at the same spot on the print bed.  I checked if the print core was jammed, but it seems to be extruding fine otherwise.  The rods that support the print head don't appear to be bent.  Any suggestions?

    Since it seems to be running diagonally (as far as I can see on the photo), my first guess is that it is something with the glass plate? For example if the bed is dirty, greasy, or soapy in that area, so the print does not bond well? Or if you did use some bonding, maybe an uneven bonding layer (too thick/too thin)? So I would first do a thorough cleaning of the bed, and degreasing.

     

    I don't know if autoleveling could cause such issues, if for example the probe would have encountered a piece of dust during measuring, resulting in an incorrect height measurement?

    It was actually horizontal when it was still on the build plate.  The first layer comes out fine, but the layers afterward have this issue, so I didn't think it was the surface cleanliness issue. 

     

    I disabled the autoleveling and manually leveled it, but the issue persists.

        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.
