Hello dear forum members,
I hope you can help me… I’ve had my brand new Bambulab for 3 days now.
Simple parts are no problem, they come out of the printer perfectly. Really good for the price, have always worked with Stratasys printers until yesterday.
But I always need support material for my printed parts and I haven’t been able to produce a stable part for two days.
Regardless of whether it is a combination of PETG with Sup PA or PLA with Sup PLA.
As soon as I print components with support material, they become very unstable in the Z axis and the individual layers can be separated from each other very easily.
He gets through the print job well to the end and at first glance the quality is really very good here too. Only the stability is felt to be lost by 90%.
What am I doing wrong here please? I use Bambu material and Bambu profiles.
A tempered inner area would be nice in those printer because for me its a temperature issue if he always purge support material the part will be to cold i would thing.
Any other ideas?
Hope you can help me.
HI, It would be helpful if you post some information about your print settings. Otherwise it is hard to judge what might be the cause of your problem.
Turning off Aux fan may help, if it is indeed a temperature issue
Hello again, all right, so ive received the brand new printer.
With Bambu Mat: PLA + PLA sup and PETG +Sup G
Standard Bambu Profiles and Material Settings, also Bambu Standart
Its the ident issue with both material combinations. If i produce with support the layers of the part itself are instable. The print look fine but during unpacking it breaks to easily.
In direct comparison to parts without usage of support mat its much better.
Settings are the same but the stability of the part get worse if we use support material.
Also tried with Generic instead of Bambu Profiles.
I tried now more temp to head, less cooling, less speed but the result isn´t acceptable.
I really think that the material change takes to long and the part gets to cold.
But i am really confused if nowbody else knows that issue already.
I mainly produce technical parts.
It might not be getting all of the support material purged out and that would cause the layers to seperate.

I agree with silver. You might want to change the cleaning settings for filament changes.

Hello together i already tried it with huge purging i thought.
Can you tell me rough numbers in relation to your experience.
From Support G (3) to PETG (2) currently would be flushed 420. Its already a lot i thought, should i double this again you mean up to 800?
By Support for PLA (4) to PLA (1) its also 420.
I havent used support for petg yet, you can try upping it and printing something small and see if it works.
Succes! Thanks a lot for your promt support.
The reason was the flushing between material change. It must be increased more or less on max and then the part itself is stable like it should be! Its a bit funny that the bambu profiles are such far away from useable ones if you want to work with support material…
Thanks again to you guys!
