Learning Notes in 3D Printing Supports

General
-
The "Goldilocks" Setting: For most applications, using a Grid pattern for support interface, three top interface layers, and a 0.15mm gap between the support and the model provides a great balance
-
Design for "No Support": The optimal solution is to design your part to avoid supports entirely through techniques like rotating parts by 45 degrees or using chamfers instead of 90-degree overhangs.
-
Designed Support Benefits: When supports are necessary, designing them yourself allows you to: Place support exactly where needed, reducing material waste.
-
Include user-friendly instructions directly on the support geometry (e.g., labels like "Support" or making them crushable for easy removal)
-
Threshold angle: The default is 30, but Bambu printers have killer cooling. You can often bump this up to 50, meaning the slicer will generate fewer supports overall.
-
Brim type: If your print has a tiny footprint and keeps getting knocked off the bed, turn on Outer brim only. It prints a thin skirt attached to the base to lock it down.
