Structured Brim For 3D Printing Warp
From Eleccelerator Wiki
I have a method to solve the problem of 3D printed objects warping during 3D printing. This method is a combination of the brim technique and the "Micky Mouse Ears" technique.
The problem looks like this, where the bottom of a 3D printed object shrinks and curls upwards.
With more difficult materials, like nylon, this can cause the print to completely detach from the bed during the print.
The reason why this happens is that the printer bed is hot, but the upper layers are cool. The upper layers will want to contract.
There's usually a brim option in 3D printing slicers to counter this effect.
But it is not always effective.
