The A3 printbed is a dedicated printbed accessory designed for Morpho printers. It includes built-in electronic components that connect to the printer, providing power for bed movement and enabling automatic printbed recognition. No manual selection is required.
After the A3 printbed is installed, click Snapshot Alignment. Studio will display the reference area of the A3 printbed on the canvas, allowing you to verify the artwork position, orientation, and printable area before printing.

The A3 printbed is designed for larger-format alignment and printing. Its printable area is 330 × 420 mm.
Common use cases include:
Before using the A3 Printbed, make sure that:
Important
If the bed latch is not fully locked, neither the printer nor Morpho Studio can recognize or lock the A3 printbed, and printing with the A3 printbed will not be available.
The A3 printbed must be initialized before first use.
Install the A3 Printbed.
The system automatically detects the printbed and starts the initialization guide.
You may choose Cancel, but printing with the A3 printbed will remain unavailable until initialization is completed.
To start the setup again later, click Setup Required.
Attach the required calibration sheet as instructed, then click Continue.
The printer will automatically begin the calibration print. Wait until the process is complete.
You can click Run in Background to continue designing while initialization runs in the background.
When A3 Printbed Ready is displayed, the A3 Printbed is ready to use.
Import the artwork you want to print.
In Design, confirm your artwork, then click Snapshot Alignment.
Wait for Snapshot Alignment to complete. Because the A3 Printbed has a larger surface area, this process may take slightly longer.
After the snapshot appears, drag your artwork onto the canvas, align it, and start printing.
Before printing, check the following:
Select the artwork.
Drag the artwork into the A3 Printbed area.
Adjust the artwork size if necessary.
Adjust the artwork angle if needed. Click the Rotate button and enter the desired rotation angle.
Zoom in to inspect the artwork edges.
Make sure the artwork remains completely inside the A3 printable area.
Ensure both the print bed and the material are flat, without lifted edges.
Make sure the print height will not interfere with printhead movement.
Note
The A3 Printbed does not support Smart Alignment mode.
Check that the bed latch is fully locked.
Then open Alignment and verify that the canvas outline matches the size of the A3 Printbed.
Use HDR Capture next to Take Snapshot to improve image quality.
The images below compare Snapshot Alignment with HDR Capture disabled and enabled.

Reduce the artwork size or move it until it fits completely inside the A3 printable area.
Printing outside the printable area may cause printing issues.
We recommend performing a test print on paper or scrap material first.
After confirming the position, orientation, and size are correct, proceed with printing your final object.
