ABS printing problem with support material

Posted · ABS printing problem with support material

Hy!

I want to print the 3D part which can be found in the attachment.
The component is designed for outdoor use therefore PLA cannot be used. Our experience is that the part exposed to solar radiation is deformed.
For the printing I use original ultimaker abs filament and RS PRO PVA HT+ which is based on the manufacturer's description excellent adherence to ABS.

My poblem is the ABS dont adherence to special PVA material.
Print settings
ABS: 245°C nozzle
PVA HT+: 225 °C nozzle

Bed: 100 °C

cooling is always off

To the bed I use UHU glue and its smoothed with wet paper.

 

Can anyone help me with what the problem might be?

 

Thanks!

Benji

    Hello and welcome to this forum, Benji!

     

    You want to support those square areas in the second pic? You may want to experiment with Support-Z-Distance and Support Roof. Try to minimize (even zero) the z-gap between until ABS sticks to PVA. A roof is better for adhesion and surface.

    It is a good practice to find the right parameters with a small part... 🙂

    Hy!

    Thanks for the answer, I try your settings asap and post my experience.

    I do not insist to the ABS material, I want an material which it does not deform from the sunlight.
    Can you recommend recommend a material that is just as easy to print as PLA?

     

    Thanks

    Hi Benji,

     

    I made good experience with Ultimaker CPE.

    According to heat resistance, it's between PLA and ABS, and the digital sundial, I made about three years ago (and which is outside all year (southern Germany)) shows no signs of deformation.

    And: ABS is prone to age by UV-radiation, CPE is almost UV-resistant.

     

    Usage with PVA: with ABS, it may work or it won't (I think that's why this combination is rated "experimental" by Ultimaker). Breakaway would be the better support material for ABS.

    CPE and PVA cooperate like a charm.

     

    Regards

    CPE/XT/PET-G and PLA as support work, too!

    @Larof: If it needs to be ABS, try ASA, which seems to be UV-resistant. But your inital question was about support for ABS...

    With this settings finally the part was printed successfully (ABS and PVA HT+ combination).
    Thanks for the support!

      • 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.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
