Hello H2D guys
I recived mine a few days ago and print nonstop with it. PLA, ABS, PETG from multiple vendors and im just happy with the printer!
But now i come to a hard opponend, PA6-CF from Sunlu.
I have the textured PEI and im just not able to keep it on the build plate. It always start to wrap up at the fourth layer.
Nozzle is at 275, bed on 120 and chamber on 65, everything 30 minutes preheated but no change to adhesion. Adapted the Bambu PA6-CF profile with lower speeds (50-100mm/s).
I know, some glue can help but im not a fan of it.
Is there maybe a trick to use a different raft material between plate and PA? Or is already a better build plate out in the market that can be used for this material? Have to print much of that in the next days
Hey, that’s really unfortunate. I’m still waiting on my H2D and planning to print with nylon. Have you tried Vision Miner Nano Polymer? It’s essentially a bed treatment you wipe onto the surface. I’ve heard a lot of people really like it. I’m anti-glue stick too, but it seems like you’ve tried everything else to print without it—at this point, it might be worth a shot just to get a functional print.
Yeah, ordered already some glues and 3Dlac to test. But for the future i need a plate which can handle PA by itself or a raft layer in a different material.
In a few days i can provide results with glue here
I did have good adhesion with PAHT on the stock plate at 120c, but nano polymer is the answer. I print a lot of nylon and its custom made for engineering filaments. Also it will stick better to a smooth PEI plate, textured was made for better release of model and durability, smooth for better adhesion. I also have a BIQU glacier plate on the way, supposedly it was made for nylon, I will post my result after it arrives.
Have your results improved at all with glue? I’m disappointed in the bed adhesion and warping on my first run with PAHT-CF. I was really hoping that the chamber heating would be more effective at preventing warping. I was also hoping to avoid glue.
Try 110-120c bed temp the stock 90c was too low, when I bumped it up it helped a lot for PAHT on the textured PEI plate. I also changed the chamber temp to 65c.
I received the Glacier plate and it does work well with nylon, but it is still not a replacement for nano polymer. Large nylon prints always tend to warp so adhesive is pretty much mandatory.
Use the glue stick. It’s cheap, easy to apply, easy to wash off, smells nice, and gets the job done.
I print PAHT-CF from my X1E as easily as I can print PLA from it — and the PAHT-CF performs far better on bridging and overhangs than the PLA.
Just finished a PAHT-CF print job last night, in fact.
I’ve had such flawless printing with the PAHT-CF that for grins, I washed my textured build plate to print PAHT-CF on just the “bare naked” plate. Not one part stuck to the plate. Each part lifted off on the first layer.
I took the 20 seconds to rub Bambu Lab glue stick across the plate in horizontal strokes going left and right and re-sent the print job. Every single part (from 3 mm tall to 100 mm tall) stuck firmly to the build plate for the duration of the 5-hour print job.
I keep the bed temps at 100 deg C, and the chamber at 60 deg C with a capped waste bin with air-tight seal over the “poop chute”.
To get the glue off the bottom of the prints, I just wash them in warm water until the glue softens then completely dissolves and washes away — in minutes.
Next, I put them in my blast oven at 110 deg C … in well under 10 minutes, they are drier than Death Valley in July.
Glue stick is essential. Bambu Lab glue stick does fine. No need for the ultra costly stuff by Vision Miner.
Reporting back that the Vision Miner Nano-Polymer adhesive is amazing. I’ve been using the smooth PEI plate, which makes it easier to see where the adhesive is applied, and bed adhesion with PAHT-CF at stock settings has been flawless (100C bed, 60C chamber). The nano polymer isn’t too expensive IMO since it doesn’t take much, and the bottle will last a long time. It also leaves less residue on the finished prints - I haven’t felt a need to wash the parts afterwards like I did with glue stick.
Once anyone tries nano polymer they will never use another adhesive, its that good. There should be virtually no residue, just some grey stress marks from removal but that can be fixed with a blow torch pass.
I actually just received my bottle of Nano Polymer as well. After how many prints would you have to re-apply on average? I did one ASA print and upon removal it seemed like all the adhesive in that spot was already gone.
I reapply it every 10-15 prints on textured PEI for PLA and ABS/ASA. More frequently for nylon. It does not look like its still there on the plate but should still work.
I re-apply every 10 prints or so. I let the plate cool all the way down and then dont touch the plate itself. The stuff works awesome. Sometimes you can feel it on the bottom of the first print. So the first time I used it I thought it was all gone. But the next 9 prints always stick.
Thanks! I see Vision Miner even says you can easily do 50 prints or more when only using PLA, but I’ll see how that turns out haha. Printed ASA, PA6-GF and PLA all on the same plate and so far haven’t seen any adhesion issues.
