Idea: Compact H2C Mini for faster everyday multicolor prints (built on AMS)

Bambu Lab Software Feature Requests

TL;DR

Many small multicolor prints (logos, text, icons) take disproportionately long due to hundreds of color changes.
Idea for discussion: a compact H‑series printer (~300 × 300 × 300 mm) with Vortek‑Light (4 colors always ready) for fast switching, built on AMS for additional colors, material handling, and supports.
Fast by default, expandable when needed — fully aligned with the AMS ecosystem.

Feature Request / Discussion: Faster everyday multicolor workflow on small parts (built on AMS)

I’m using a P2S as my first 3D printer and have been printing multicolor parts frequently over the last few months. This post is not meant as a demand or roadmap request, but as a discussion about a multicolor workflow limitation I’m running into — and a possible idea to address it while keeping AMS central.

The workflow issue I’m seeing

A lot of everyday multicolor prints are small but highly segmented:
logos, text, icons, decorative parts, nameplates, etc.

Even though the parts themselves are small, they can easily require hundreds of color changes, which causes print times to grow disproportionately due to unload/load and purge cycles. For me, the main downside here is less about filament waste and more about very long print times for relatively small jobs.

A compact H‑series idea to discuss

This made me think about a compact H‑series concept that builds directly on the AMS ecosystem, while improving speed for frequent color changes.

Concept outline (for discussion):

  • A compact H2C Mini, positioned between X2D and the full H2C

  • Build volume around 300 × 300 × 300 mm

  • Vortek‑Light setup inside the printer (1 fixed nozzle + 3 Vortek hotends)

    • 4 colors always ready

    • optimized for fast, frequent color switching

  • AMS remains the foundation

    • additional colors

    • material management

    • spool backup

    • support materials

In this setup, Vortek‑Light would handle the most time‑critical color changes, while AMS continues to provide flexibility and expansion.

In simple terms:
four colors fast by default, more colors when needed.

Why this feels relevant, especially for hobby users

  • Many real prints live in the 3–4 color range → significant time savings

  • AMS workflows stay exactly the same

  • Existing AMS units remain fully usable

  • A clear step beyond X‑series multicolor performance without going all the way to a full‑size H2C

Design & living‑space aspect

My printer sits in a living space, and one thing I really appreciate about Bambu printers and AMS is how clean and integrated they look. Some toolchanger concepts are extremely powerful, but they also tend to become physically large and visually “workshop‑like” very quickly.

A compact, enclosed H‑series printer with internal fast color switching and optional AMS expansion would keep the appliance‑like look that many users value.

Open questions to the community

  • Do others see the same time issue with small multicolor prints?

  • Would a compact H‑series printer below the full H2C make sense to you?

  • Especially for users who like the H2C concept but find it hard to justify for personal use?

This is meant purely as user‑experience‑driven discussion, not a demand. I’m genuinely curious how others see this idea.

They probably have something like this in the works. The issue, say using the H2C setup in a chassis like the P2S / X2D etc., is you’ll lose tons of bed space and you’ll add lots of cost. So essentially you are left with something that could be almost into H2S cost territory with a much smaller print area than a $650 X2D.

You get all that extra weight in the tool head, and next thing you know you need the beefier H2 style gantry setup and all the other “more expensive” equipment from the H2C… Nex thing you know the savings from the small size doesn’t justify choosing that over just starting with an H2D/C etc., to begin with.

And the reason I say that is I would think the chassis / mechanical parts that make up the size are not the expensive parts of the printer. The internals, electronics are (fancy stuff from the H2C are). So really.., how much cost savings do you think you would get making a machine such as this unless they design something completely different in a smaller scale that can use all the rest of the same chassis?

Would this really be any different than the current 300 X 325 H2C

Just wait and see what the next X2 printers have. An X2 printer having a 4-nozzle Vortex or some other tech that can reduce multicolor printing waste will be a smaller H2C. It may even debut some new features that H2C doesn’t have :slight_smile: , fingers crossed.

  1. I am convinced this post was written by an LLM
  2. Yout “vortek light” is just the vortek system with only 3 spares. You are not saving any space when you still need 2 extruders.
  3. 300×300 is so close to the H2D and H2C already. What difference will it make.

Whats bad, i read it all any way, knowing it was just a verbose way of saying I want a smaller multi color printer.

That’s a fair point — whether this lives in X‑series or H‑series matters less to me than solving the everyday multicolor time issue in a compact, living‑space‑friendly form factor.

8

You’re probably right that a lot depends on internal cost trade‑offs we don’t see.

From a user perspective, my point was mainly about workflow and time savings; how Bambu would place that within X or H series is up to them.

9

Size itself isn’t the main point — the core issue is reducing print time for small, highly segmented multicolor jobs. The form factor and internal switching are simply means to that end.

10

In terms of nominal build volume it would be close, yes.
The difference I’m getting at is less about raw dimensions and more about positioning: a compact H‑class option focused on everyday multicolor speed for small parts, rather than the full‑scale H2C use cases.

11

How does what you said reduce the print time over the current 300mm, vortek, AMS, system?

12

Fair question.
To be clear, I’m not claiming this would be faster than a full H2C using Vortek — there is overlap there.

The point I was trying to make is more about positioning and target use cases than raw capability. The current H2C is an extremely capable machine, and there are certainly users who want and value that level of performance.

What I’m describing is less about outperforming the H2C, and more about offering a more compact and approachable entry point to fast multicolor workflows for small, highly segmented prints — particularly for users who don’t need the full scale and flexibility of the current H2C.

13

Call it X2Maxxxx, if you like :wink:

14

You are misunderstanding me. You have described the H2C exactly. I am asking what is different?

Nothing you have said is different than the H2C except 300x300 VS 300x325

Let me try to make it clearer by breaking it down into a few concrete points:

Size:
The idea is a more compact machine with a smaller overall footprint, optimized for use in living spaces rather than workshop environments.

Number of nozzles:
Compared to the H2C, this concept deliberately uses fewer Vortek hotends, focusing on the most common hobby scenarios instead of maximum flexibility at all times. AMS would still handle additional colors where needed.

Price:
With fewer hotends and a reduced focus on production‑oriented hardware, this would sit in a lower price tier than the full H2C, making advanced multicolor workflows more accessible to hobby users.

Intended use:
The H2C is clearly designed for workshop‑scale or commercial production workflows. What I’m describing targets hobby‑scale multicolor printing, especially small, highly segmented parts where time and waste matter most.

To give a concrete example: I’m currently printing a relatively small 3‑color part on my P2S, and despite its size the print takes around 7 hours purely due to frequent color changes. That’s the kind of everyday hobby scenario this idea is meant to improve.

16

Then it would not be an H series printer. What makes a series the same is that it uses the same frame. (or at least as a general rule, you can not count this for the A series)

Ill put these together since you are pretty much saying the same thing. Saying fewer vortek hotends is just how many induction nozzles you have. The basic extruder design would have to be the same.

Your whole point about the AMS still handling the additional colors doesnt make sense because that is what it already does.

17

I think I understand You want a printer with 300X300 build volume with a 256X256 foot print ?

Or are you saying a H2 with less vortek nozzles? I dont think having 2 less vortek nozzles alone would make it much cheaper.

18

Let me try to clarify the difference one last time, because I think we’re talking past each other.

Series / frame:
I’m not arguing about what Bambu would or wouldn’t call an H‑series printer. The point isn’t the label, it’s the intended scope of the machine. Whether that ends up being called X or H is secondary to the use case.

Number of nozzles:
Yes, fewer Vortek hotends still means the same core extruder architecture. The difference is not technical novelty, but intentional reduction — designing around a small, fixed number of fast‑switching colors that cover the majority of hobby multicolor jobs, instead of maximizing flexibility for all scenarios.

AMS:
I’m not saying AMS would do something new. The point is that AMS already works well for occasional additional colors, while fast internal switching would handle the frequent color changes. That division doesn’t change AMS — it changes what the printer is optimized for.

Feature‑wise, yes, there is overlap with the H2C. The difference is optimization and target use: improving multicolor printing for hobby workflows (time and waste on small, parts) without designing the entire platform around workshop‑scale or production‑oriented scenarios.

19

So an H2c with 4 induction nozzles rather than 6, ?

20

Let me clarify.

I’m not suggesting an impossible footprint like a 300×300 build volume in a 256×256 chassis. What I mean is a more compact overall machine than the full H2C/H2D class, positioned between X and H in size and intent.

And I agree that simply having one or two fewer Vortek hotends alone wouldn’t magically make it cheap if the core extruder architecture stays the same. The difference I’m pointing at is intentional scope reduction: fewer always‑ready nozzles, designed around typical hobby multicolor jobs, rather than maximum flexibility for production workflows.

So the point isn’t a radically new mechanism, but a different optimization target: hobby‑scale multicolor printing where reducing time and waste on small, highly segmented parts matters more than designing around full workshop‑ or production‑scale use cases.
