AquaSys 120 not sticking to Ultimaker PC

[jficara 2]

Greetings,

 

I am running into an issue with the AquaSys 120 and Ultimaker PC filament, with the support autogenerated by Cura. The AquaSys 120 support filament is not adhering to the Ultimaker PC material at all on the sides of the part. The AquaSys 120 filament is bunching up in chunks. I have attached the Cura project which is the latest attempt with slightly slower print speed, 10% reduction, as recommended when having this type of issue. 

 

Any help or ideas would be greatly appreciated.

 

Note:

The brim, composed of the AquaSys 120 looks good, its clear and adheres to the build plate fine

The part made up of the Ultimaker PC looks good, its opaque and adheres to the build plate fine

Since the brim, made up of the AquaSys 120 looks clear, I doesn't appear like its a hydroscopic issue with the AquaSys 120, but I will try drying the Filament after the current print run completes just in case. 

 

Equipment:

Ultimaker S5 Pro Bundle

Ultimaker S5 Firmware 5.8.2.0

AA 0.4 for Ultimaker PC

BB 0.4 for AquaSys 120

 

Software

Cura 4.8.0

AquaSys 120 material plugin version 1.0.6 

 

Settings:

Attempted with: Default Cura Settings for with  0.15mm layer height and 100% fill

Attempted with 10% speed reduction for (45mm /sec PC and 27mm/sec for AquaSys) with  0.15mm layer height and 100% fill

 

Filament:

Ultimaker PC Transparent

AquaSys 120

As Aquasys120 does usually stick pretty well to Ultimaker PC, I think the issues in your case come from the support generated by Cura. They seem to be very small and fragile. I suggest you increase the supports a bit by using the join distance and horizontal expansion options in the support section of Cura.

I have the same equipment you have and the same issue occured... Don't know why. I fill like the solution given by Dim3nsioneer should help! 

 

Good luck! Give us some news about your results!

I am running into the exact same problem - the AquaSys won't stick to the PC no matter what I try. I have a slightly different configuration with AA0.6 (3D Solex) & BB0.8, but all the same results. PC (black) is printing great, AquaSys is adhering well to the build-plate and to itself, and the extruded AquaSys looks good (no bubbles, etc). Material is fresh from the bag right into the material station. But the AquaSys will not stick to the PC part and it also seems not to want to stick to the PC of the prime tower either.

 

The reverse situation is no problem - PC sticks to the AquaSys just fine at the top of the supports and my supported surfaces look good. I just cannot get the support bottom interface layer to stick to existing PC, as happens when support starts on the part. I'm running the AquaSys at 245C, the max listed temp and I've tried reducing the support floor speeds down as low as 8mm/s. I've tried increasing support floor density and tried different support floor patterns (concentric, lines, etc). I just cannot get even the smallest dot of the AquaSys to stick to the top of the PC.

 

This is super frustrating, as outside of this issue, the material works really well. I'm running out of things to try, save for pushing the AquaSys temp up outside of its listed range. My PC is printing well at 275C, so I wonder if printing the AquaSys at something closer to the PC temp might work better. I'm hesitant to go beyond the 245C listed max temp, but other than that, I can't think of anything else to try. Maybe increase the flow rate on the support floor to try to squish it down more? Try to get the chamber temp up somehow (it's running around 40-42C right now)? Anyone have any ideas? It is a material station certified material, so I kind of expected better results - maybe someone from Ultimaker could offer some thoughts?
