eSun ePA-CF Strong warping on Pro2

[Alexandre]

Hello everyone.

Since yesterday i tried to use the esun ePA-CF filament on a raise 3d Pro2+ but i have warping issue.
(i saw that was another topic with the exact same subject made a few months ago and tried to use theses advices to solve my problem)
In fact, after the first four layers, the part i'm trying to print twists and ends up detaching from the bed.

I tried to preheat the printer for 15mn at 80° before starting but the issue remain.

I also tried to print on either a glass bed or the normal bed but that doesnt change anything. The part start to bend after few layer then detach from the bed. (the raft to be more accurate) (also the normal bed i am using is brandly new)

I did a few tests by changing the nozzle and bed temperature by 260 (nozzle) and 60 (bed) to 280 (nozzle) and 80 (bed) but nothing changed.

Also, i start to print a raft of 8 layer. The first layer has a height of 0.5mm and the others have 0.26mm.

I dont use any glue by the way. (never used and still managed to print without problem material like PLA, ASA and PC)

So, any advice or tips?

Thank you in advance for your answers.

Although you may have seen success with not using a bed adhesive, it is highly recommended to use one to ensure you have the best chance of success time after time. We recommend using Magigoo PA or PVP glue (different than PVA glue) as a bed adhesive.

What can also be done is preheat the bed to 110c instead of 80c prior to starting the print.

Lastly, this material is not on our open filament program so this may not print all that well as we have no pre-made template for it. This material can still work, it just may come down to slicer settings if the proper print prep has already been followed.

I use this material on a Pro3 and the only way I can prevent warping is:

SLOW DOWN! Go very very slow. and prevent long straight lines that can warp.
Try using a concentric infill (also on the bottom layer) and maybe adding some small holes or notches here and there to prevent very long straight extrusion lines.

I use a 0.6mm nozzle
Preheat chamber 100 degrees for 20 mins.
Temperature extruder 270
Bed 60 degrees.(If i go higher, I see more warp?)
All speed settings 35 mm/s except for the first layer which is 15mm/s

And turn off your airconditioning if you have it. The material is very sensative to temperature differences
If I fill my bed with small plates 5cm x 5cm, all the outside ones warp, and the inside ones dont because of airconditioning. I havent tried this yet, but I hear that wipe-walls help to keep the material temperature stable.

We tried using cura, without raft at like 400mm/s and, even if the part is still a little warped, its really better. (its printable at least)

But the part seems to inflate a little? Maybe because i didnt use a dryer?


Also, i have another question about Raise Filament.

I can find two serial for the PC filament from Raise 3D. 1103060003 and 51101040A01. Is there a difference between these two references?

And, if not, why?

Thank you in advance wor your answer.

Thank you in advance wor your answer.

What may also be affecting your print is the amount of bottom or top surface layers. The same thing goes for too much infill as well. The higher infill tends to make your print warp due to the material shrinking a bit when extruded. If your infill is high enough, the shrinking force increases, causing the print to eventually begin to pull inward and warp. The same effect can also be seen ith too many top and bottom layers. (the proper amount would depend on your layer height)

As for the other concern, 51101040A01 would be the "SKU" of the material that was purchased. 1103060003 would likely be the material's batch number which can vary from roll to roll.

51101040A01 is the SKU (thats written on the filament i have)
For the 1103060003, are you sure about that? I mean, even on a website like farnell, thats the serial used.

(and 51101040A01 is not used on farnell though)

Ok, thank you for your answer. But that mean website like farnell and rs are mistaking then?

I can let our team know to contact them and see if they can correct this as it appears they are referencing the batch number as the material SKU. Thank you.
