Wall thickness around holes


Recommended Posts

Posted · Wall thickness around holes

Hi all. I may have missed it but I haven't yet found the answer. 

If you have cura set for walls to be two rows thick and the actual wall is 6mm thick with a hole vertical in the wall. This puts two rows around the hole. Is there a way to put more rows around the holes to make them stiffer?  

I haven't found a way yet.

    I haven't played with this much so take a close look at the preview.  I'm going to assume you mean more walls where the "tube" with a hole in it passes through an area of infill.

    Put a support blocker over the hole tube.  Scale it and move it until it covers the entire area you want to beef up.  In the Per Model tool there is one for "Modify Settings for Overlaps" and choose Select Settings and then Wall Line Count.

    I think something like that is what your looking for.

    Cool.  Thank you thats just what I needed. I didn't know that option was available to modify areas like that. Very useful.

    I know this is an old post, but it's one that I found when considering a way to increase hole strength/dimensional accuracy without increasing filament/print time across a larger volume of infill. Increasing infill helps on both fronts but may waste time and filament in a larger space with few holes. In my situation, "Extra Infill Wall Count" was a good solution. By adding additional wall(s) at the edge of the infill, I got extra walls around the holes. This creates a column of plastic that is solid via attachment to top and bottom layers. I was then able to reduce infill percentage for the rest of the model. It also adds those walls in other areas bordering the infill, but in my case was a good compromise that still saved time and filament.

    This is what I usually do. The left hole has one of 5axes cylindrical support blockers configured to "Modify Settings for Overlaps" and 5 walls.  Screw connections do much better with more material for the head of the screw and the nut to put pressure on.  They will still deform over time, but not near as readily.

      • 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
