What if a Dispenser Toolhead was coming for the H2D?

What if… a Dispenser Toolhead was the next expansion for the Bambu H2D?

Hey everyone,

Let’s play with an idea for a moment:

Imagine the H2D ecosystem expanding with a Dispenser Toolhead –
a modular head designed to extrude pastes, gels, silicones, solder paste, functional inks, or even chocolate.
Fully compatible with the quick-swap system.
Built around a Luer-lock syringe, a mechanical locking lever (like the one used in the cutter tool), and a clean, compact design.
Equipped with interchangeable nozzles for fine or wide dispensing, and seamlessly integrated into Bambu Studio for flow control and material profiles.

A hypothetical concept – but packed with real potential:

Such a toolhead would unlock a whole new range of material workflows for the H2D: viscous fluids, gels, pastes, even food-grade materials.
And with interchangeable dispensing tips (e.g. Luer 18G–25G), it could be tailored for everything from micro-dosing solder paste to laying down wide silicone beads.

Application Use case
Electronics Prototyping Dispensing solder paste for SMD pads – even with fine nozzles
Soft Robotics Extruding elastomeric silicone or flexible gels
Gasket/Seal Design Applying custom silicone or PU gaskets along 3D contours
Food Design Chocolate, Nutella, icing – beautifully extruded
Bioprinting Agarose, gelatin, cell-laden materials for lab use
Ceramics & Clay Modeling with paste-based clay or fireable materials
Functional Inks / Adhesives Conductive ink, UV glue, or epoxy dosing – controlled and clean

Why this would make sense technically:

  • The H2D is already modular, and the mechanical interface is well established.
  • Power and data lines are ready to support new toolheads.
  • The locking system works well and could easily support a dispensing tool.
  • Bambu Studio could simply add a “Paste Mode” or “Dispenser Profile” – similar to laser or pen settings.

The flexibility of materials is the key:

  • Use standard Luer-lock syringes (10–30 ml)
  • Attach interchangeable tips (e.g. 18G–25G) based on material viscosity
  • Support heated cartridges for temperature-sensitive pastes or food
  • Enable volumetric extrusion, not based on filament metrics

What if this is the next big accessory for the H2D ecosystem?

Your thoughts?

  • Would you want a dispenser toolhead like this?
  • What would you build or print with it?
  • Should Bambu Lab bring something like this – or are they already silently working on it…?

Looking forward to hearing your ideas!
Cheers,

Yeah and the image is AI generated too. Unless I don’t know my numbers and there’s two 8s when you count down from 10 and the countdown ends at 2 instead of 0

It’s within the capabilities of the hardware. Developing the software to generate the appropriate tool paths would be the biggest hurdle in my opinion.

What purpose would it suit besides glue ? for the laser 3d models ?

I might use the solder paste dispenser if it were available. It would need to be closed-loop with a high-res camera though because for it to be worthwhile the accuracy would need to be less than 0.1mm relative to the board.

All this AI, and it didn’t even bother talking about pancakes. :roll_eyes: Where’s the intelligence part of the AI, am I right? Hahahahaha. :pancakes:

The line markings aren’t evenly spaced either.

I get kind of exhausted of all the AI slop, and now that we’re getting a flood of AI post it’s just, uggh. They’re all the same, structured the same, and the same lifeless post over and over again. I wish people would use their actual words instead of trying to constantly hide behind AI.

@user_1098976850 (XDready)

Might I ask, who are you and what compelled you to make this post? Serious question. It seems often enough we get some random post put together by AI, and posted up by someone that’s completely new to the forum and has little to no real connection to us, our world here, makerworld?

I can’t seem to find you, XDready, anywhere, so who are you?

I mean the idea is one I’m sure we’ve all had, about the expandability of the print head with how it’s designed. So it’s not like the post or question behind it is anything wrong or off, it’s just, it feels like these post come out of left field and I often wonder what the intention is.

As I sit and write this, and think about it. The only thing I can think of is some sort of attempt at market research, based on some of the questions you posed at the end. Like a loosely gathered focus group.

They’ve updated the AI image and it still looks like garbage XD

I’m so glad we’re back on track to the idea of a precision pancake maker. :pancakes: I thought that dream had died. :sob:

Haha, that’s funny. I missed that one when looking at the post’s edit history. Would probably have been better to just fix/adjust it in photoshop :sweat_smile: It’s not really fixed now, just a different kind of wrong.

Yes. How much of this world must we be tortured with before someone listens to what we actually want/need.

I had to put together pancakes like a barbarian yesterday.

Hi everyone – and especially @Josh-3D, @Gimpers, @Leonilian and others who jumped in here,
First off – thanks for all the reactions (even the skeptical ones).
I came here to explore an idea, and clearly it triggered some strong opinions – which is great. That’s what good maker forums are for, right?

Who am I?
I’m Alm-Öhi, and I live up in the mountains with Heidi and Peter.
While looking for a better tool to make pancakes, I stumbled across the H2D from Bambu Lab – and realized it was just missing a dispenser to help us serve up beautiful, G-code-controlled pancakes up here :smile:
So I stepped into YOUR kingdom, without asking for permission. Sorry for that – next time I’ll be sure to check in with you first, @Josh-3D :wink:
And no, you won’t find me online – I’m up here in the alpine wilderness.
A true backwoods tinkerer.
But our mountain is pretty high – and from up here… the view is broad.
You see things.

And yes, we use AI here too.
We call it “Echo” – you shout into the mountain, and reflections come back. Not always perfect, but often helpful.
Sometimes they spark an idea that wouldn’t exist otherwise.
Maybe it’s not “maker-authentic” like your brilliant hands-on projects – but it’s part of our toolbox now, too.

Pancakes? What’s this really about?
@Gimpers unintentionally nailed it:
It’s not just about food metaphors – it’s about seeing the H2D as more than a 3D printer. Many people here rightly expect further improvements in FDM. I’m looking outward – wondering what other functional areas the H2D could serve.
Bambu Lab has opened up a capability – modular toolheads – at a price point normally reserved for industrial setups.
Sure, there are other platforms (like Snapmaker, xTool…).
But for my kind of pancakes, the H2D looks like the best foundation.

What would I actually do with a dispenser toolhead?
• Dispense solder paste (like @featherweightalt) for PCB prototyping and small batch production
• Apply elastomeric silicone or adhesive precisely onto 3D-printed parts (for sealing, bonding, flexibility)
• Extrude ceramic paste for electrical insulation in high-voltage designs
• Deposit conductive inks, UV-curing resins, or epoxy directly into parts or flex assemblies
Example: Imagine a quadcopter arm without wires – conductive paths printed directly into the structure
(That could also unlock new possibilities for MID-like designs)
…everything from the point of view of prototyping and small-scale production

And what does “XDready” mean?
• X = any direction, idea, or material
• D = dimension
• ready = not finished, but open to what’s next
Like “HD-ready”, but with more solder paste and fewer televisions :smile:

So yes – even up here on the mountain, we have ideas.
Not just the ones already at the table :wink:
And who knows… maybe Bambu Lab already has a sketch tucked away in a drawer.
Cheers from above,
XDready

Hey Josh-3D – I posted a full reply above, including some thoughts on your comment and where I’m coming from. Thanks for being direct – it pushed me to be clearer too.

Let’s keep our snacks free of plastic and metal vapors—don’t print food on a machine that’s been melting those materials! If you want to 3D-print candy, use a dedicated confectionery printer like the Mycusini 2 3D Chocolate Printer: mycusini® 2.0 3D Choco Printer :wink:

That tool would be usefull also to dispense epoxy, insulation paste, glues if its precise enought

If the same machine could cut a PCB, Etch the pathways, place solder powder/solder paste and place components…All you would need to do is melt the solder. Very few people would use this capability, but some businesses would love it. Rapid prototyping machine

Exactly it would be awesome

I want them to expand with a UV printer tool head and take up the competition against ankermake/eufymake E1.

They have everything needed.
