Pre-print - Processing

Optional Stand:

If you have chosen an optional stand, you only need to split the model into the QR Code and the stand within Bambu Studio and then arrange the two parts on different build plates to suit your needs.

There are currently three different desk stands to choose from, which are automatically generated to match the dimensions you have selected for your QR Code.  When both parts have been printed, you place your QR Code into the stand, it is as simple as that.

AMS or PAUSE for colour prints

Once you have created your QR Code, download the STL or 3MF file and add a PAUSE or Colour change at the correct layer.

Follow these instructions:

1. Open your downloaded QR Code in Bambu Studio
2. AMS only: Make sure you have at least two filaments selected.
3. Press the [Slice Plate] button.
4. Move the BOTTOM layer marker upwards (6 - 1.20 in the preview image) until the back of the QR Code is no longer visible in the preview.  Which layer you need depends on your settings, do NOT assume it is layer 6.
5. Right-click over this layer and…
   1. AMS: Select “Change Filament”, and choose your filament for the data portion.
   2. Manual: Select “Add Pause”.
6. Print your QR Code.
7. During the print process…
   1. AMS: The AMS will swap the filament to the filament you chose.
   2. Manual: The printer will pause, remove the filament you used for the base portion and insert the filament ready for the data portion. Resume the print job.
8. Your QR Code will finish printing.
