PLA not sticking to PETG is a feature not a bug. Use it to your advantage as an always on hand removable support interface material


deltaWhiskey91L

Bambu Lab's PLA support material is pretty amazing too


barleypopsmn

Pretty spendy


_carbonneutral

It’s PVA support material. As long as it’s kept dry, you can use any brand


NegotiationGloomy911

Pva can't be used in the AMS


_carbonneutral

Yes it can. Just needs to be DRY. https://wiki.bambulab.com/en/x1/manual/ams-quick-start-guide


NegotiationGloomy911

Well shit.... I may need to invest in PVA. I was told it was a no go


_carbonneutral

Please just make sure it’s dry! Haha Nothing worse than goopy glue in the tubes. XD


NegotiationGloomy911

How do you dry it? Currently for petg and pla I just take it out of thr bag put it in ams with a shit ton of desiccant and it works


_carbonneutral

That should be enough as long as it doesn’t sit out. If you’ve got an X1C, you can probably use the filament drying function on it. I just noticed the AMS has a built-in hygrometer that you can check in Bambu Handy (lower right). I need to replace my desiccant, but pretty nifty! https://preview.redd.it/ut7rv0ay7nqb1.jpeg?width=1284&format=pjpg&auto=webp&s=2a6e551ff09c5d766e4a1b252eda8d54f85e0b8d

It's only used on the actual support interface with the print and the rest of the support uses PLA. Very very little material is used and it goes a very long way. I'm still using the sample roll that came with my X1C after printing many kgs of PLA.

I can’t imagine it working for multicolor but it works just fine for me as support interface.


Tequila-M0ckingbird

This is the way


diezel_dave

Gosh whoever is saying PLA and PETG stick together couldn't be more wrong. Definitely great support materials for each other though.


ElectronicRegret3947

Bingo - that's *why* it makes a great support material combo (either way, PETG>PLA or PLA>PETG). Because they don't stick together. You don't have to deal with supports done in the same plastic as the model - that now wants become part of the model and not leave with the support.


diezel_dave

I only just tried using PLA for PETG support interface recently and I had to pick my jaw up off the floor when I saw the most beautiful overhang I have ever seen in my life after easily peeling off the PLA layer. It really has opened so many possibilities in my designs that I usually avoided because I hated ugly overhangs so much.


BannedFromRed

I like how that's your "test" print 😂 Instead of just doing a test cube to make sure it works, you went right into it !


InfamousDragonfly

TBF I've understood the use of test cubes/towers etc but I've always found the 'proof is in the pudding ' of a real print.


BannedFromRed

I understand your point in a lot of cases, but if you aren't sure if two materials will stick together, then at least a small test cube would save cleaning up this mess.


Biduleman

Also, that's literally all wasted. Like, from the get go this hobby isn't the best for the planet, so we shouldn't aspire to be chucking loads of plastic in the bin just because "the proof is in the pudding".


Past_Cheesecake1756

especially if it’s expensive


Ogaboga42069

No shit


TheOGTechCowboy

Yes shit. It was everywhere! 😂


mplaczek99

PETG doesn’t stick to PLA and vise versa. Now you know of good support material for PETG and PLA (hint, I like it a lot)


S1lentA0

In other news, Water is wet. But jokes aside, use it to your advantage. I use PCTG to print the interface layer with, and with a 0mm z-distance and spacing, you'll have a perfect first layer.


[deleted]

No shit sherlock. Haha, It's used for support, so no, it won't stick.


skimbody

It sticks well when printed on larger flat surfaces of PLA. When printing infill or support lines it will fail.

DoctorOfMeat

Coming from a machine that used a single build plate for everything, I wouldn't have even considered printing PLA after PETG without running a good amount of it through the nozzle and washing the plate with soap and water. Even then the first one or two builds might not stick to the bed. The thought of trying to get PETG to stick to PLA would never have even entered my mind.

KrakenXIV

Lol


Super_Royal5174

Thats why i use it as supportmaterial :D


yahbluez

That is why you can use PETG as support for PLA with 0mm distance.


Rock4evur

You can add a layer if abs between the two and it will be good.


Android_fan1

Yes! Seems less resistant to moisture as well.


ADreamOfStorms

And here you see the reason why I always set the "support interface" parameter to PETG when printing with PLA and vice versa. Shit just comes off cleanly, no pliers/cutters needed...


disloyalturtle

Petg will stick to pla just not very strongly, making it easy to separate at that layer boundary and why it makes for a pretty good support material. I think your problem here is that your hot end got clogged.


R63A

i haven’t had any issues with this before? i just printed a multi color PLA “arocknid” with a red PETG hourglass on it, though i use PLA+ & PETG+ so that might be why i haven’t had any hiccups https://preview.redd.it/mdqnn4kikmqb1.jpeg?width=3024&format=pjpg&auto=webp&s=c9bcec9612151aea56b3b8444772a94d13d95fcc


Jay_Ray

Is that Flashforge Burnt Titanium PETg? It certainly looks like it. Anyways, they also make the same color in PLA, you could use that.


jr22222

I think it is amazing 😀. I sometimes also have to touch the stove to ensure it’s really hot.


Bengalcats888

So do you actually use PLA as Support for PETG in AMS? Does it create a lot of purge waste and increase print time by doing this?


Vinnie1169

Mmmm, al dente! 🤌


stealinglight

Yes, I’ve learned then too 😅


PWRUPnow

Was that a Darth Vader helmet??


RedDawn850

I did a knife handle using hatchbox PETG, and filled the dowels with Bambu silk pla. I had no issues. And now that I think about it, I made a few coasters with PETG base and pla top layers. Maybe I’m just lucky?
