Working with 40+ small objects in Cura


Recommended Posts

Posted · Working with 40+ small objects in Cura

Hello all;


Cura slows down drastically when I place 40+ small objects on the build-plate.


I am trying to put my printer to good use by printing some ear savers for our healthcare workers.

Object is simple in design and optimized for 3D printing so one peace takes 15 min to print. STL file is 120kb in size. I could place large quantities to print at once for overnight printing and weekend prints. As I place progressively more objects on the build-plate and arrange them, Cura slows down dramatically. It takes very long to multiply an object and place it. It even slows down the menu window. with 40 pcs on the plate total file size shouldnt be more than 5 megabytes yet cura takes upwards of 5 minutes to update a menu or place another object. Computing power is not an issue, tried it on 3 different machines with same/very similar results. I have worked and printed models that are 100mb in size, why is quantity of objects an issue?Stack.thumb.JPG.7c055b7775c67d80df5e7eae98d6643b.JPG


Here is the process in a bit more detail in case Im doing something wrong.

Because of the shape of the object I can place 15 of them on the place of my S5. but because the are thin (1mm high) I can stack them on top of one another. So I created a "slice", second object, one layer thick, with same shape. I place the slice on top of the first part and print it with breakeaway material. that way I can create a stack 10 pcs tall (and more) that come apart easy once complete. I then group this "stack" and multiply it to fill the plate surface. With 5 stacks on the plate cura takes 5 minutes to multiply a single stack and place it, and it progressively gets worse.


Thank you!

      • 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
