Problem With Cupping/Distortion at Base of ABS Print


Recommended Posts

Posted · Problem With Cupping/Distortion at Base of ABS Print

I posted this in the "Cura" section, but maybe more appropriate here since I'm asking for help with a print.  So, I'll give it a shot here (apologies if I'm violating board protocols).


Trying to print a hollow cylinder in ABS.  OD is 23mm and wall thickness is 1.5mm.  Height 30mm.  Having trouble getting bottom without the "(" shrinkage (see photo).   Tried raft and brim - no difference.  Both raft and brim seemed fused to cylinder (hard to remove).  Currently printing at 240 extruder and 105 bed.  Printing bottom 10mm at 1/2 normal print speed.


Using Anet A8 in enclosure.  Cura 3.2.1 is slicer program.


I'd keep experimenting, but there are so many variables it would be a big assist if someone could clue me in as to where to focus.


BTW, yes, ABS is the much preferred medium for this application - I don't want to go with PLA. 


Anyways, appreciate any advice.

      • 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
