Prime Tower, Single Material

Is there any way to have the prime tower print with just one extruder?

 

The majority of my problems stem from underpriming my PLA, or my prime tower failing as every single bond is dissimilar materials... And I don't have trouble extruding PVA without priming anyway.

If you have a problem with the adhesion between the two materials you may want to increase the thickness of the tower. With 4mm you usually should not have any troubles for recommended combinations of Ultimaker materials.

    Or ability to have 2 towers - one for each material.  And you can print one or both depending which material(s) you feel need the tower.

     

    The downside is if you have two separate towers you are printing twice as much because currently it does this: change nozzles, then print ONLY ONE layer of tower, then print TWO LAYERS OF ONTO THE PART, then repeat.

     

    With only one tower it has to print on the tower just after the nozzle change and again before it changes to the other nozzle.  Either that or the tower layers would have to be twice as thick as the print layers.  That would have a danger of heavy undextrusion on the tower and overextrusion the first few seconds of printing the part.

    I forget where I posted this before, but I'd like to see two concentric towers: PVA as a "core" inside of an outer PLA circle.

     

    Each material would be on top of itself, the glue would be well contained.

     

    Two towers would work as well.

     

    Lastly: A solid PLA core/surround, with the current every-other-layer tower inside/around it. Probably PLA in the center would work better - if there's a bad PVA layer you'll end up with blobs inside the circle, causing issues for next layer.

     I've used up to 14 mm. I can get failures. I feel my material may be sub-standard, but fixing the towers makes sense anyway.

    -----------------

    Again, as PVA primes just fine, having ONLY a PLA tower would work for me. It's cheaper to use twice as much PLA anyway.

    The thing to keep in mind is that you would lose extra material as the towers would be required to print double layers to keep the heights consistent.

     

    There are a lot of possibilities, but options should be available.

     

    Edit: George may be right about what gets what as far as double layers go. The rest is more information to consider.

    I don't know about you, but my PLA costs a lot less than my PVA.

     

    My PVA hardly needs priming, if at all.

     

    A tower that was MOSTLY PLA would be strong and cheaper than 50-50.

    Every other layer still has PVA, but enclosed/captured by a solid, contiguous PLA cylinder.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        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.
