PLA Expansion


Recommended Posts

Posted · PLA Expansion

I'm trying to print a 3d file that has two parts that join together like a dovetail joint. When I print the file on an Ultimaker 3S using PLA, the pieces are a couple millimeters too large and don't fit together. However when I print the same model with similar settings on a FlashForge (also with PLA), the pieces slide together snuggly. I can provide some more details but generally speaking, is there a simple solution to preventing 3D prints from slightly expanding? Again, most of the settings for the model are similar (I'm using Cura for the Ultimaker and Simplify3D for the FlashForge).

 

Any suggestions would be appreciated.

    Use the Engineering profile for your S3 which is much more dimensional accurate. The key to get success is to print slow and with equalized speeds for the different wall types.

     

    If you get still problems you can use the horizontal expansion with a negative value to compensate the expansion.

      • 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
