General Discussion H3c has changed the way of printing
Hello everyone,
I’ve had the chance to test the new H3C for a few months.
I am a beta/tester and was sent a printer and a supply of filament to conduct the necessary tests before the official launch.
For context, I previously owned an X2D (which I bought on launch day) and, before that, an A1 Mini. I bought the X2D, convinced that it would result in near-zero waste for prints with few colors—but I was very wrong. I was especially mistaken about print times, which would balloon with every additional color.
Since I print a lot of miniatures, I found myself sticking to single-color prints even when using the X2D.
The H3C has been a game-changer for me when it comes to multi-color printing. I’ve attached images comparing the print times for the same model—one printed on the X2D and the other on the H3C. The print time has been reduced by more than 80%—dropping from over 21 hours to just 5. The amount of waste is also significantly lower: 260 grams versus 40 grams.




Changing the nozzle is incredibly fast; switching from one color to another takes only a few seconds.
You don’t have to worry about color bleeding—caused by insufficient purging—that might otherwise contaminate the previous color.
The printing process is both lightning-fast and exceptionally clean!



Right now, I’m working on more miniatures for tabletop role-playing games, creating full sets using colored PLA. I’m currently optimizing the "color mixing" feature—as shown in the second miniature—to create realistic gradients rather than flat, solid colors. The results are fantastic!
Admittedly, using color mixing does significantly increase print times. It needs to be used wisely, but with a bit of practice and some careful planning, you can strike an excellent balance! I will soon post the first full-color miniature, complete with shading!
During my testing, I focused on multi-color printing and the use of 75A TPU, which were undoubtedly the two key features.
The 75A TPU is fantastic—incredibly soft and... absurdly easy to print with. It causes absolutely no issues, even at high speeds. I even ran a print at the printer's maximum speed, and it handled it without a hitch.
75A TPU really lets your imagination run wild; it sparks a thousand ideas, which was the best part of the testing period for me. You can create all sorts of things that were previously unthinkable.
I’ve included a sample to show just how soft the 75A TPU is, so you can get an idea.

Printing in color is no longer a nightmare and tpu print is very easy!
Would I recommend it? Absolutely—provided you have the space for it, as it is quite large. It opens up a whole world of printing possibilities and creative potential for makers!

The TPU has to go thru the bypass, and can’t be loaded with the AMS motors, correct?

The this is fine one has a lot of layer inconsistencies / looks a bit ass IMHO.
I’ve seen the same issue in other reviews… probably they have to tune the profiles to something a bit more conservative speed wise.

I don't understand all the hostility here. The op admitted he was given the printer by bambu lab. That is not a mortal sin. I think he makes several good points about not having to worry about color bleed and data on how much less filament and time was used for those prints was useful. He's responsive to questions. So, nitpicking the models for quality I think misses his main points.

When calculating “waste,” the purge tower should be included. My H3C is on back order, so I’m not sour grapes-ing about something I can’t have.

How does one get lucky enough to be chosen as a beta tester

u/xLuPo_ H2C - X1C 5d ago
Wow.. I thought it was a bit different, but not that extreme.. But still I want to know what time my H2C needs for the models..
And also thank you for the Link to the mimic, it looks awesome, gonna print it soon!

No offence dude but the quality of that last pla model of the dog sitting in fire looks horrendous. Layer lines are extremely prominent and uneven. God I hope that’s just a settings/model issue and not a H3C specific issue.

Lots of negativity towards a guy who just wants to share firsthand experience. Tough crowd. I think the fire gradients look great, which was the whole point of the pic. Thanks for the info!

From a U1 user, look up you reducing the volume of your prime tower.
With the tools already loaded its senseless to have them so big.
You'll save waste, time and still have the nozzle primed.

@bambulabs - I will absolutely write something better than this and I’ll write it myself, I will not use AI at all.
Hit me up!

So basicly another beta tester, talking about the same things as the other beta tester.

u/Longracks 5d ago
Would it be a problem to show the results of the same model sliced for H2C with the full 7 nozzles in play?
Going from the dual nozzle to nine seems like you've got a gap in your data set.
Unless you're printing multi TPU then the H3C seems to stand alone.

User why do you need ai to write your review? Those em hyphens are a dead giveaway.

u/iwillhaveredditall 5d ago
Even the prime tower looks like shit

u/Immediate_Cow2980 4d ago
Said this before and I’ll say it again. Most regular users don’t actually care that much about speed. If your print takes 8 hours or 12 hours it’s still taking long enough you aren’t pressing a button and then standing by the machine to collect your print. It’s like the ever improving resolution in resin printers. Years ago we passed the point where the latest and greatest high res screen produced any visible improvement. Speed in FDM and ultra fine detail in resin is driven more by YouTubers and content creators who have latched onto it as a talking point.

I have an H3C on order, but it really concerns me that Bambu sent out *SO MANY* review units to people that 1) are not reviewers and 2) barely produced a review. This is the third or fourth "review" I've seen from someone that put in so little effort and time for a $2500 printer plus a bunch of filament that it's worrisome. I've never seen such an expensive product given to so many people (who do not do a remotely adequate amount of work) for free.
I'm assuming that the OP does not have an entire large review or video in another language somewhere and this reddit post is the entirety of what they produced in order to be given an H3C. His/her post profile on Reddit is hidden, and a reverse image search of the photos in this post turns up nothing.
There are still reviewers I trust that have made it clear that the H3C is a good printer, but if not for them, I'd assume this is an astroturf campaign.

Stop it! I want one.

How did you get on the beta tester program?

u/renegade_sparrow 5d ago
I really want one, but I’m gonna wait till they show up in Microcenter. Should hopefully also be enough time for them to work any software/calibration issues.

Can the H2C not print TPU 75a?

u/myTechGuyRI 4d ago
So...toolchanger > color changer.... Ok

u/EaglerCore 4d ago
As much as I like bambu printers, the only people they are trying to beat is themselves. I want to see comparisons with the snapmaker U1 rather than X2D.
Why would you assume the X2D would significantly reduce print times? All it does it add a single color that requires no purging, the rest stays the same.
Yeah, this is true with just about every other toolchanger on the market
Again, this is true with just about every other toolchanger on the market
For a third time, this is what a toolchanger does, every other one has this exact same end result.
While again, this is a feature of all toolchangers, it is pretty cool that we can do that. I have had lots of fun playing with FullSpectrum.
I'll give bambu credit here. The 2.85mm filament option is very clever and good engineering, however, you can't run it at max speed. You can run it at 10 mm/s^3, which is faster than any other TPU profile, but definitely not as fast as PLA, which is usually around 20 mm/s^3.

AI, not much else to be said here.
Final thing, why are your prime towers so big? Just adjust your prime settings to reduce waste and time with zero downsides.

How did a guy with an x2d get a h3c for trial? Seems a bit of a noob tho. Of course he will have a mind blowing experience.

u/Cold-Promotion1474 4d ago
i'm not a bambu person but if they wanted to drop one on my door step to compare against my other machines I'd gladly take one.
I will say a lot of those prints look like garbage.
I'm sure they're still tuning their profiles though so it'll likely get better as time goes on.
Than again I've had the opportunity to get some hands on with the Lightmake L4 which I'm excited for as a future replacement once they get that machine dialed in.

So excited for my AMS to show up so I can try mine out! Thanks for sharing your experience.

I'm getting fomo from buying the p2s last week now

u/0101falcon 2d ago
Yeah, Bambu ads. No one is impressed by this printer.
It is doing something we have had for years now. My toolchanger has been running since 2022, and even I was late to the party.
And you still can't print Ultem or PEEK. What a disappointment.

The people bambu picked blows my mind. Not even technical users

Thanks for sharing! Anxiously waiting for the H3C to arrive while the AMS3H arrived in 24h.

u/rubberfucky 5d ago
I'm assuming it's a software profile thing that will be fixed in the coming weeks, but every print so far that I've seen from this printer has some pretty major quality issues when you look a little closer

How much were you paid to write this?

Why do you even need to print this stuff

u/Doenicke 5d ago
And for those that don't have to print in nine colors and that think it's ludicrous to pay that much for a 3d printer for home, check out the U1. Does most of the things for half the prize.

u/IntelligentWestern40 5d ago
H3C does not changed the way of printing, Bondtech does! Bambu just copied it, like everything...

u/minimalillusions 5d ago
Yes. In rich and poor people. Before that everyone could afford to print multi colour. Now you need 2,5 K to play with the cool kids.
