Printly Preflight beta

; pre-print check for FDM printing

Find the risky layers before your printer does.

Printly Preflight checks the print file your slicer creates, called G-code, before you press print. It flags possible problems, like a bridge that may sag, and suggests what to check.

3 What to check

Printly's suggestion card: Bridge Sag, marked critical. The bridge is probably too long to print cleanly without support, and Printly suggests adding supports under it.

; how it works

Three steps before you print.

  1. Upload your print file

    Export the file from your slicer as usual and drop it into Printly, right in your browser.

  2. See what Printly flags

    Printly rebuilds the print in 3D and flags what may cause trouble, such as a long bridge, an overhang or a tall, thin part that could be knocked over.

  3. Get a suggested next step

    Printly suggests what to check or change in your slicer, starting with the most important one.
