Process Large Files on MatterControl Dashboard and Add to Cloud Library for 3D Printing

This article will describe how to process large 3D files (STL, AMF) on your MatterControl Desktop version and add to your cloud library for 3D printing. This method is used when large 3D files cause stability issues on the Touch Interface.

It is important to note that the current processor within the onboard Touch Interface is limited to slicing files that are around 20mb in file size. If your file is larger you may need to slice using your desktops' more powerful processor. If slicing with the Touch Interface takes longer than 5 minutes the part is a good candidate for processing on your desktop computer.

To slice (generate G-Code) and then add this G-Code to your cloud library for 3D printing from the touch interface follow the steps below.

TIP: If you are designing your own mechanical parts avoid using filleting type tools until final iteration of your design, this will reduce the overall file size.


  1. Open MatterControl on your desktop computer.
  2. Ensure you are signed into your Account in the top right corner. This step will ensure that your 3d printer touch interface and your desktop computer have synchronized the printer settings.
  3. Select your 3d printer from the dropdown if not already shown.
  4. Select in the Settings section that the QUALITY and MATERIALS are set correctly.
  5. Select Queue to return to the print loading page.
  6. ADD the file to the Queue
  7. Select the part in the queue 
  8. Select Export-Export as G-Code and save the G-Code file in a convenient location on your desktop computer.  MatterControl will now slice the file and save it on your desktop computer as a G-Code file.
  9. To add the G-Code to your cloud library click Library->Cloud Library then Add
  10. Browse to your G-Code file and click Open.  Your sliced G-Code file should now be in your cloud library.  
  11. To print the sliced file go to your 3D printer and open MatterControl on the Touch Interface.
  12. Select Library->Cloud Library and select the G-Code file previously processed on your desktop computer.
  13. Select Edit->Add to Queue 
  14. Go to the Queue select the file and Print  
  15. You have Now successfully processed a file on your desktop computer and added the G-Code to your cloud library for 3D printing.
