Suggestion for "Brim" option

Posted · Suggestion for "Brim" option

I'm having a lot of fun with the new Cura, and the new "brim" option is certainly an improvement.

However, it occurred to me when cleaning some brim off a print that instead of a continuous brim, a series of small tabs (say, 5mm x 5mm?) that alternated around the outer perimeter of the model (as long as they didn't intersect with the model or another tab) might be just as good, and much easer to remove (by just bending the tabs)

    Brim is important only for large parts - for example 4 to 8 inches long because the warping lifts the corners. You need every possible amount of brim for these parts to hold the corners down. Especially with ABS which has even worse warping.

    The old Cura did brim also but it was kind of a hidden feature. It was called "skirt with distance 0".

    Actually, I found that brim was the solution to an adhesion problem with a smaller part that had multiple points of contact with the bed -- in this case a level-2 Menger Sponge rotated so two of the vertexes went through the Z axis and then cut to form a triangular base (which is composed of smaller triangles). On the initial print, several of the triangles detacted; brim provided extra support enabling them to stick to the bed until they joined up into the larger structure.

    Furthermore, brim has the advantage of being much easier to clean than raft, and provides a much better bottom surface to the model -- a big win if you're printing sections for later assembly.

    The downside of brim is that it's a bit finicky to clean it from within "fjords" -- thus the suggestion.

      • 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
