Regretting switch to H2D? I do. Print quality

  • Slower when doing single color or multicolor under a hundred changes. (Slower then all other Bambu machines)

Unless I’m misunderstanding your metric, that seems misleading. The multicolor being slower would only maybe (but not likely) be true if you’re not utilizing the 2nd nozzle, which I’m not sure why you would if you’re doing a multicolor print where it’s optimal to use it. It’s absolutely faster for multicolor at effectively any amount of changes, not just those over 100.

Here’s a 25x25x10mm multicolor shape (83 changes on a single nozzle) on both the P1S and H2D:

P1S:

H2D:

H2D knocks it out of the park and more than halves the number of changes, so I’m a little confused by what you mean there.

Well I don’t know anything about your blocks example but I’ve talked about it a lot and I’ve posted numerous real world print examples of my print times on both machines all about of how the H2D is slower than any other Bambu printer on everything except over a hundred color changes and yes I do mean using both nozzles. The H2D prints so slow that that the P1S can load 1 color at a time on for example 20 swaps and beat out the H2D. The H2D prints slow and you can see it with yours eyes that it prints careful and slow although better.

I’m too lazy right now to repost all my real world examples printed on both machines but if you’d like to revisit the thread: “H2D slower compared to A1” you will find all the info there. There is also another thread titled: H2D prints slower but better than the X1

That is my experience as well on multicolor prints. Less waste, significantly faster

You’ve compared the same exact prints on both the H2D and other Bambu machines? Printed on both machines and you found the H2D to be significantly faster? I have to ask how many color changes? If it near a hundred or more then yeah. But it’s 20 color swaps or 50 then I have to say it is hard to believe. It depends on the model of course but I think all my color models at 66 color swaps or less the P1S is faster. I recently posted 2 screenshots both machines sliced and printed on both machines and the H2D is 82 minutes slower. This is on a print of my Ninja Turtles Helicopter Cockpit Body with a print time of around 12 hours.
I’ll repost the pics here. I will admit though slower the H2D prints it a little bit better.

H2D 4 colors 13:21
P1S 4 colors 12:39 (finishes 82m ahead)


If you check my thread “H2D Supports failure” you’ll see the H2D failing to print jobs that 4 other machines , including machines that are not made/supposed to print abs/asa , have printed flawlessly , 100s if not 1000s of times. Yet H2D fails to print the supports properly. Do I regret the buy? dont know yet. Will depend on how much time i need to tune this thing to actually print things that a 10 times cheaper printer actually prints out of the box…

I seriously think that this is a slicer/profile issue.

I cannot imagine that the printer can print perfect models and suddenly would fail on supports.

Yeah its a slicer problem, the way it generates supports is flimsly at best.
Why I strongly believe this now? If you check my thread ive posted comparissons between how Orca Vs BS generate supports. TLDR Orca generates the EXACT number of interface layers that you set, and in a 45 degree or a bit less/more, but still at an angle in regards to the rest of the support structure, where BS generates them at 90 degrees vertical (meaning you are looking at them from top-down), AND (i think since BS V2 was introduced)_Studio also adds an EXTRA interface layer (probably incorporated as it expects dedicated support material and 0 top-z used) meaning that when you set 3 interface layers, you get 4 and so on. Moreover that extra layer is totally uncontrollable , Example, :ive set interface speed at 80, the Support Interface Layer runs without any input from me at 10, and the flow is also down to 0,18 from 4.50 that the rest of the interface runs with .

Additionally, I have a friend with his own p1p, and he is struggling the last 3 days with trees supports just breaking , on a model he has already printed successfully.
MY P1P works as it has been working the last 10 months+, and I have successfully printed the same model he is trying.
I am using his settings, yet my machine suceeds, his fails
The only difference? I use Orca, he uses BS studio.

Probably its about time Bambu to take the Cue and make ammends with SoftFever. Lets face it, while they are kings at making printers, they suck at making slicers, and its evident with all the new issues that arose with the new BS . But wont happen cause “closed ecosystem yayy”

Are you using Bambulab.-Filament or a different brand ?

Yet another example of Bambu slicer being inferior to orca, resulting in horrible print quality on the H2D. Lookup GitHub issue 7240 (can’t post links). Avoid crossing walls is completely broken in BS and does nothing, resulting in really bad prints.

It’s the best bigger format printer, but man it leaves so much performance on the table due to Bambu Slicer being such an inferior product

Come check my thread H2D supports failure. I have documented another field where BS VS ORCA comparison is… interesting to say the least.

I just purchased the H2D printer, and have never been able to get a complete print yet. Getting tickets from bambu result in no action by them, just a link to their page and instruction manual, and then you get a message that your ticket is assumed to be resolved and closed. Its a piece of junk and does not work.

What kind of issues? What material/build plate/settings?
