Print quality: Part and Support material interface is TERRIBLE

Posted · Print quality: Part and Support material interface is TERRIBLE

Greetings,

I'm trying to print a part with a couple of internal ribs, and the interface between the support material and the part is a gnarled mess.

First, a photo

As you can see on the right side a bit, there are supposed to be two ribs running the length of the part, but they are a complete disaster. The support grid came away as intended, but everything above it was, well you can see for yourself. I have already set the support gap to 0 to try to limit this effect.

Bed is leveled with .002" shim and the first layer is printed nicely. I tried to print two parts one after another, and the 2nd part came out with half of it in shambles (even though the exterior finished well...). No delamination there.

Here's another part from a couple of weeks ago. You can see the support layer is built up, but then the next part layers are terrible.

Do I need to increase my grid density to limit the amount of bridging that occurs? Is there something other than slow, slow, slow that is needed? Belts are tight and lead screw is freshly lubricated.

Guidance?

      • 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
