Posted (edited) · Poor surface quality on thin section print. *FIXED*

Hello everybody, im reaching out for some advice on how to improve the quality of this print as it has me stumped.

 

The part is a piece of plastic trim i reverse engineered from the original part and will be used on a show car so must really look great.

 

With that in mind, i printed the part in a specific orientation, and moved the z-seam top always the back (unseen) side of the part. see below

Ultimaker S5

Cure 4.1

retraction is on.

0.2 layer height

 

 

 

support is printed in TPLA with Brakeaway roof/floor

    it appears that travels might be to blame?

     

    on each layer the travels happen before the shell of that layer, but i guess it's affecting the layer below?

    There is an option "limit support retractions" which remover retractions when moving in a straight line between 2 supports.

     

     I'll try reprinting without this enabled.

    for those that are interested. that setting entirely cured the problem. id recommend this for thin walled parts that have support on both sides of the wall.

     

    see before and after pics

      • 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
