Dude, thank you for this video. I printed a skull that has celtic markings all over it using the "support for PLA" product and it was awful. Its still stuck in all the small gaps even after using tons of force to get it off. Just not a good experience there. So I bought some PVA to try for a reprint. Glad to see it worked out here.
I bought this stuff, really keen to use it on an MCG model I wanted to make for a co-worker. All the research I did said you have to dry it first, given it's really hygroscopic, so I whacked it in the X1C and ran the filament dryer, and the bloody thing expanded and now won't fit in the AMS... I was so peeved. Bought a new filament dryer yesterday that hopefully does the job better. I can think of quite a few models where this stuff will be a godsend. For the standard Support W, I find it often squeezes out a bit from the interface layers. I've used that to try and gently lever the supports away from the model before snapping them off and it often comes away as a smooth layer atop the supports instead of remaining on the model and needing to be peeled away.
I think the reason the print snapped so easily is because the pva was contaminating the PLA inside the hotend. also pva dissolves really neatly in an ultrasonic bath :P you can also drop in a magnetic stirrer, or honestly, just give it a shake every 10m
its likely treated in some way because i tried some PVA filament and when it got really dry it just got mega brittle and stiff and started snapping all the time
There is an option to select the support material {for the whole model} in the support section of the slicer menu. for individual designation you would have to manually paint the support areas you want.
I would watch it but not sure if others would. I just got Bambu w/ AMS so I need to look into making supports better. I am ok with the additional time it would take to change filaments. Thank you for the reply.
It probably could, BUT, PVA is very hydroscopic, so I would think that it would absorb some moisture being out in the open. For small short prints, you could probably get away with it, but I don’t think it’s recommended
In Bambu Studio, the "Filaments for Supports" section of the Support tab. "Support/raft base" is the material to print the support itself out of, and "Support/raft interface" is the material to print the interface from. Unless you're trying an impossible print (where the support can't be mechanically removed), you'll want to just use a different material for the interface, and use the same material for the supports themselves as the model.
PVA works fine, but you have to make sure it’s very dry. TPU is not recommended nor have i tried it, but I don’t think it’s a good idea. The path that the filament takes to the extruder is so long, with multiple motors pulling the filament through. It’s going to be hard to get consistent results when the filament stretches so much.
I ordered TPU and i wait them Until now i print pla,pla with silver powder and pla plus. The pla with silver powder its the most strong from the others pla
@@swe872 Iv absolutly done manual swaps for simple 15 min prints that require just a small bit of supports in a weird area. My problem is Bambu people thinking an AMS is the only way for anything when there is half a dozen alternatives.
Thanks for the video. Dude, your audio is substantially low. Have you compared your gain structure to other videos, advertisements...? Improbable. Your video person needs to lern a whole lot about audio gain structure and gain paths. When the ad or subsequent video played I was blasted because your audio was too stinking low. Read up on audio mastering.

When you get the PVA, just be patient and let the water do its job. This stuff is sweet for use cases like that.

is there lots of waste for switching filaments at every layer?
What was your purge volume? Iv always had trouble with the support material still being in the nozzle and contaminating my print
PVA in China is like...USD 5 dollars a roll. Not sure on the quality but he, it's just for supports. Thank you for your video. Useful.
its likely treated in some way because i tried some PVA filament and when it got really dry it just got mega brittle and stiff and started snapping all the time
What settings are you using? I can't get the PVA to print well no matter what.
So how do you designate which model part gets PLA and how the supports get PVA. Do you use AMS?
There is an option to select the support material {for the whole model} in the support section of the slicer menu. for individual designation you would have to manually paint the support areas you want.
Have you made a video of using PLA as support for PETG and vice versa ?
I have not, but is that something you would be interested in?
I would watch it but not sure if others would. I just got Bambu w/ AMS so I need to look into making supports better. I am ok with the additional time it would take to change filaments. Thank you for the reply.
can the bambulab a1 combo print pva?
It probably could, BUT, PVA is very hydroscopic, so I would think that it would absorb some moisture being out in the open. For small short prints, you could probably get away with it, but I don’t think it’s recommended
How do you switch between different materials within the support?
In Bambu Studio, the "Filaments for Supports" section of the Support tab. "Support/raft base" is the material to print the support itself out of, and "Support/raft interface" is the material to print the interface from. Unless you're trying an impossible print (where the support can't be mechanically removed), you'll want to just use a different material for the interface, and use the same material for the supports themselves as the model.
Thanks for the video. By the way, that rook should print just fine without support.
This stuff has been around for like 15 years. Like longer then hobbiest 3D printing.
which 3d printer did you use?
Bambu P1S w/ AMS
@@PrintPractical thank you! I heard the TPU can get clogged in the AMS and I was wondering if PVA too.

good video thanks
You use this for support interface or whole support ?
In the video, I do both. Experiment 1 is using it as the support interface. Experiment 2 is using it as the whole support.
LOL the resin printer ROOK
AMS IS A MUST .. OTHERWISE CANT BE DONE
1: Tool changer
2: Idex
3: Print pause and filament swap.
I can go on but AMS isnt needed.
@@NWalker-zx6xu ah yes, i will use a tool changer on my bambu printer, i also will filament swap 2 times for each layer

Why this stupid music in the background? Difficult to understand the language.
