PA6-GF Default Profile Too Hot - Works Great After Lowering Temps

Bambu Filament and Accesories Filament

I wanted to share my experience with Bambu’s PA6-GF filament. The default profile (100 °C bed, 65 °C chamber) runs too hot in my testing. Prints barely held on the smooth plate with glue and showed noticeable warping. On the textured plate, adhesion failed completely, even with glue.

I opened a support case with Bambu before going down this path, but the response was that the material is simply prone to warping. Unfortunately, the possibility that the default temps might be the issue was ignored after bringing up multiple times.

After experimenting, I found a simple fix:
• Bed: 50 °C
• Chamber: 50 °C

No other changes were needed to the default profile. With these temps, adhesion is excellent on both the textured and smooth plates with glue. No warping, no detaching, and parts stay firmly attached even hours after printing finishes.

Hopefully the Bambu team can review the default RFID profile for this filament. The material performs great once temperatures are dialed in.

I really like the RFID system Bambu uses, but it doesn’t currently allow tuning for cases like this. And based on what I’ve seen across forums and groups, I’m definitely not the only one running into PA6-GF issues out of the box.

PA6-GF impossible to print

Which one did you use, .4 or .6 nozzle? Can you share the printout?

100/60 worked with glue for me.
50/50 worked with just aquanet.

I tried the default 100/60 with aquanet, and everything slipped at around layer 30. You’ll also have more success if you print only one item at a time.

0.4 nozzle.

I’ve printed a bunch of things with these settings so far but this one was by far the longest and tallest on a textured plate with glue.

Little things I print by object still but finding that’s not even necessary on textured plate with glue.

I’m not a huge fan of the smooth plate so I’ve stopped using it now that I’ve had so much success with just textured and Magigoo PA.

The recommended printing speed of the Bambu Lab pa6-gf is 130 or less, is this part okay without modification?

Only setting I changed was bed/chamber temp

Hey, I just started playing with the Bambu PA6-GF and had similar issues with it sticking to the texture PEI plate.
Drying - dried with Eibos dryer PA setting for 8 hours (right out of the bag) and then in the AMS2 on the PETG setting for 10 hours.

Plate - Bambu PEI Textured cleaned with isopropyl (91) and a blue shop towel - this works great for PETG

Test 1 Stock settings on X1C .4mm nozzle - dynamic flow immediately peeled up and I stopped the print

Test 2 heat bed bumped up 5C - same problem but slightly better

Test 3 heat bed 115C Chamber 45C Nozzle 275C - dynamic flow finally stuck, the square I printed peeled on a corner after the first layer and when the inspection finished and printing resumed, it promptly stuck to the nozzle

I cleaned my plate in between each test and after test 3 I cleaned and printed PETG with no issues

Test 4 same heat settings and added the purple glue stick to all the plate - print finally stuck really good.

This does not seem very optimal. I will give the lower temp setting a try once I clean all the glue off the plate.
