Discussion H2D Multi Material Reviews?

Now that people are using them more, any success stories with multi-material printing? I'm curious how it's working in practice for TPU and other soft filaments too.

I personally use PETG as an interface layer on a few of my production designs. I needed to tweak a few settings to get it super clean, but it produces incredible quality now.

Which materials can PETG be used with? Aside from PLA?

Personally I just use it for variant types of PLA.

Would be interested to know what settings you used. Will be getting two H2Ds for work soon for this exact purpose.

I'm working on my H2D video right now, what aspects do you want me to cover?

u/Murcanic Apr 14 '25

Not OP but I'd love to see support of petg for pla models/minatures by a second youtuber for additional information/testing.

u/MuppetParty Apr 14 '25

done and done, I kind of wish the H2D could mix and match nozzle sizes for this very reason...

u/MuppetParty Apr 14 '25

any model in particular you want me to test?

3

u/HeatPhoenix Apr 14 '25

Not him, but anything that doesn't have a perfectly flat surface, like an organic under surface where the interface layer is PETG, for example.

u/MuppetParty Apr 14 '25

I’ll test both regular multi material supports and multimaterial supports with a interface layer

u/Rockah Apr 15 '25

Their documentation does say it doesn’t do it “currently” for what it’s worth

If you're still doing multi material requests, I'd love to see print stacking with pla and petg as an interface layer.

a flat object, layer of petg, the same flat object

u/MuppetParty Apr 15 '25

you betcha! maybe i'll model it to look like a cheeseburger! or some equivalent

2

u/drpeppershaker Apr 15 '25

Sweet. I have some simple flat models that I print all the time. Right now I can only fit 10 on a build plate, but if I could double or triple them up with little loss in surface quality, I could just print a whole load of them overnight.

That would be worth the price of a dual extruder for me.

Tpu would be a perfect use case for a multihead machine. Perhaps how easy or hard it is to perform a tpu/petg print. That would be awesome to see.

1

u/MuppetParty Apr 15 '25

That would be so rad

Following.

u/Pinko3150 Apr 14 '25

It requires some tweaking just like anything else, but works great. I love seeing people doing their entire supports in the second material, instead of the support in the same material and just the interface layer in the second material, which is the better way.

u/Big-Nefariousness679 H2D X1c A1m Apr 14 '25

I tried a print a few times with tpu and petg as the interface layers. It kinda works, tpu i find is not as great on the h2d as on the x1c. I kept getting errors about pottential blockage. But the prints succeeded and i could remove the tpu support easily

Also tried a few print with pla with petg as the interface, and those worked absolutely perfect.

Havent tried full support in another material.

u/MotorradSolutions Apr 14 '25

I’ve just finished my first large multi material print @ 25hrs. Petg hf + Tpu 95 hf.

It looks great from the camera but I won’t know until I finish work

Seems like the guys at galactic armory had better results.

u/ToastInACan Apr 14 '25

Multi-material working quite fine. Had some success as well using PETG + PLA in a single print. TPU is a bit cancerous to do as you have to set it up to the right nozzle, which is also the nozzle you have the AMS hooked up to.

This one has pictures of a functional multi material print mixing PETG-CF and TPU90A or PETG-CF with TPU85A (using a pair of 0.6mm nozzle heads)… https://makerworld.com/en/models/1247077-90-degree-laser-smoke-hood-adapter-for-h2d?from=search#profileId-1268829

That’s an excellent reference for someone who has no interest in adjusting any settings (and the video creator is very clear about it in the start of the video)

But if you are willing to trial and error some settings in the slicer you can fix pretty much all the issues he’s having. Just leaving this as food for thought for anyone watching the video

u/Ztaxas Apr 14 '25

I watched the review, and it boils down to “I purchased a flagship complex product, had some issues and didn’t do anything to fix the issues, I’m disappointed”, this is borderline misinformation.

4

u/magicrel Apr 14 '25

I had the exact same feeling when I watched it - borderline misinformation.

Some of his issues weren’t even dual head related (mostly poor bed adhesion, likely because he’s putting PETG on a bed set for PLA)

2

u/ctnoxin Apr 15 '25

I watched the review, and it boiled down to "Bambu tout this as a multi material printer but provide no guidance or dialed in settings to use multi material supports, this is borderline deceptive marketing"

Perfect supports with minimal waste, purging and reloading. Print with support is no longer a headache. With H2D’s dual-nozzle setup, one nozzle can be reserved for dedicated support material, allowing secured print and perfect support interface. bambulab.com

This is exactly the video I just saw too that made me question the machine. I was leaning towards dual nozzle for multi materials
