I am currently attempting to calibrate a spool of eSun ABS+ Silver on my P1S printer, but am facing extreme difficulties with layer adhesion. Despite having dried the filament for 8 hours at 70°C, the issue persists. My goal was to print a temperature tower to find the optimal printing temperature, however, no matter the temperature setting, no layer seems to adhere properly. I can easily separate the individual layers with just a finger, a problem I’ve never encountered with any other filament before, even though I have experience printing with various materials including ASA, PLA, PETG, and TPU from different manufacturers.
I am utilizing a 0.4 CHT nozzle which has performed flawlessly up until now. As a test, I printed a temperature tower with eSun PLA Marble and the result was excellent with proper layer adhesion, which implies that the issue seems to be specific to the ABS+ material.
Here are my current settings along with some photos of the temperature tower.
One thing I’ve noticed is that the nozzle tends to push some filament aside during printing, as can be seen in the images. This problem exacerbates as the printing temperature is lowered.
The layer adhesion is so poor for me with both that I can simply snap off the individual layers of the temp tower with my thumb without any effort. I’ve never seen anything like this with any other filament no matter what temperature was used for printing.
In case you didn’t know, eSun has filament and profile settings created for Bambu Lab printers you can download from their website (from the download tab) These have been working fantastic for me.
I have now printed some parts with the filament using the mentioned profile from eSun. The parts look quite good so far, but I still find that the layer adhesion is pretty bad and the parts are relatively unstable. It’s possible that I just got two bad rolls.
Did you use the filament profile as well as the process profile?
Also, it may not be the issue but I had all sorts of drama’s trying to get my aftermarket hotend and CHT-type nozzle to work with hotter-temperature filaments. I put it down to the placement of the thermistor which is quite a bit further up the heatbreak compared to the Bambu one. As soon as I changed back to the original hardened nozzle the problem went away.
I have no problems with the CHT nozzle, it prints just as well for me as the original. I have already printed several kilograms of different ASA filaments. So far, all have run smoothly.
I did notice you have the flow really turned down (.96) for this filament. How was that in the profile or did you do that. You could just be under extruding. .
this is a widely known problem with eSun’s ABS+, a lot of discussions on reddit about how bad it is with layer adhesion. Their regular ABS doesn’t have that problem apparently, so it’s the plastic that they alloy the ABS with that makes it not stick together well. Another reason to move onto ASA!
Thanks for this! I had a problem with infill sticking to each other and I’ve tweaking the settings for 2 days now! After downloading this my calibration cube is now amazing!
I have warping issues with eSun pla+, I can manually turn off the aux fan but how do i use a custom profile.
I can create a custom filament profile in studio but i cannot add this profile to filaments stored in the ams. when i choose an ams slot it just prints with that filament profile.
Hi, I print bonsai pot with ABS + , no problem at all with the esun profiles, just perfect and strong, also the support are super easy to separate… The only problem that I have is that every print I have to wash the plate otherwise the next part doesn’t stick.
Hi
I just had a similar problem solved with PETG. The problem was too much cooling on the bridges… and too much cooling overall. So I would suggest you to try lowering the max fan speed in your filament profile.
This thread is an archieve now so it might not be usefull… but if can help so people it would be nice
