Hello, im having a problem with shrinking in certain areas, that i cant seem to get rid of.
Im not sure whats going on, but i as you can see in the pictures theres an inward going shrink in the bottom part. This shrink only happens where the bottom plate is.
The bottom is 2 mm thick, and the shrink is only in that area.
The starting angle from the build plate is just about 45°
Ths bottom plate is 3 layer bottom, infill and 5 layer top. 0,2mm layerheight and 3 perimiters in walls.
It is a common Bambu problem that so far no one managed to fully fix.
Comes from a mix of layer speed, flow rate and wall speed.
The material you are using is a significant factor in the question of whether shrinkage occurs including being enclosed or not.
Which type of filament are you using specifically?
Whilst shrinkage is a problem, it is not a problem of Bambu Lab, it is a physics issue related to how some materials act when changing from their normal state to their melt point and then back to their normal state again.
im using bambulab pla basic, on a A1, but i dont see this problem on a less steap angle. with same material and so on.
How big is the model? Can you show a screenshot of the slicer screen with the whole shape in the frame?
I only need to see the section that meets the build-plate, no need to divulge any secrets.
If the model occupies a large amount of the build plate and the model is tall, it could be something a brim could help with. It can help to spread the heat out from the model.
