Inside out or Outside in

Recommended Posts

Posted · Inside out or Outside in

I always try to give consideration to whether a print would be better printing the outer perimeter first or whether to print the inner first. Usually the decision is based on what curved outer surfaces the model has and whether curving inwards (in which case print the outer first) or outwards (in which case print the inner first). This decision can usually prevent the first perimeter, either outer or inner, printing with no neighbouring perimeter to stick to and half overhanging nothing.

However, when printing something like a ball shape that curves outwards for the first half and then curves inwards, it's impossible to decide and the problem is that once sliced you can do nothing about it half way through.

Cura really needs an option to add a bit of intelligence to this option and automatically print either outer or inner perimeters first depending on the slope of the curved wall being printed. 

Does anyone else think that this would be a useful option to add to Cura and, if so, how to go about making the suggestion to them.

Thanks for "listening".

      • 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
