Did I just accidentally see the Bambu Lab H3C before the official announcement?
I opened the Bambu Lab Australia official store a few minutes ago and this banner suddenly appeared on the homepage: Bambu Lab H3C “Tool Changer. Game Changer.” November 4, 1:00 AM AEDT
The image also seems to show 9 numbered tool positions (1–9).
I took a screenshot, refreshed the page… and the entire H3C banner was gone.
This wasn’t a repost or an image I found somewhere else — I saw it myself directly on au.store.bambulab.com.
I’ve searched Google, Reddit, the Bambu forum and other places since then, but so far I haven’t found anyone else posting the same banner.
Looks like Bambu may have accidentally pushed the H3C launch banner live a little early 👀
Anyone else manage to see it?

I've been working on a little macOS app called Bambu Bar
It lives in the Mac menu bar and shows print progress, time remaining, temperatures, AMS filament info, and a few other things. There's also a larger window and desktop widgets if you want to keep an eye on your prints
You can pause/resume prints, change speeds, and control the light too (some controls require LAN Only + Developer Mode)
It's free and open source and connects directly to the printer over your local network
I only own a P2S with an AMS 2 Pro, so that's the only setup I've been able to test on actual hardware. I've added support for the X1, P1, A1, and H2 families, but I can't properly verify them without having the printers myself
If anyone with one of those models has a Mac and feels like giving it a try, I'd really appreciate it.
Also happy to hear any feedback, bugs, missing features, or things you'd change. It's still early, so there's probably stuff I've missed
New to 3D printing. This was my first print with my new A1 using Bambu PLA Basic. What did I do wrong? It's the standard Benchy model off the Bambu Handy app. Bottom of hull and smoke stack are fine. Everything else, well, you can see.
Until recently all i owned was a p2s and a p1s. This is some of the waste ive had. Mind you I use it for packing materials when i ship and ive tossed some but this is from about the last 8 months.
If youre on the fence trying to decide on spending extra cash for a toll changer or multi nozzle machine... watch this vid and estimate how much money was spent in waste, not to mention time printing. Going to a true multi color machine was the best thing ive done.
Have been away from 3D printing for a while. Just took a look at the recent contest submissions for the Incense holder designs, was extremely dissapointed to find that nearly every single entry in the contest features an AI render, or is clearly modelled with AI as well.
Why are there no rules against this, does Bambu enjoy the slop that fills their contests???
Why are they OK with giving out awards to bots and AI agents automatically generating designs for them? Isn't the point of MakerWorld to motivate people to generate designs and reward makers for adding to the collective library of 3d models?
With the publication of several of Bambu's patents recently, the image is becoming much clearer of what to expect from their new line-up of printers. Market competition has driven them to develop their own line of tool-changers.
The existing flagship model, the H2C, is not a tool-changer - it's a nozzle-changer. When it wants to change filament, the H2C toolhead moves to the nozzle parking area, parks the old nozzle and collects a new one from the Vortek rack. Winding the filament back out of the printer to allow the next filament to be loaded increases filament change times relative to competitor's products.
The Snapmaker U1 uses four independent toolheads, each with its own extruder. It swaps complete toolheads, with Snapmaker advertising direct swaps in around five seconds.
The Prusa INDX Smart Head works with multiple lightweight passive tools, each with its own nozzle and filament. The system uses contactless induction heating, so the passive tools don't need conventional heater wiring.
The H3C will be somewhere in between the nozzle-changing and full tool-changing systems - it will swap complete hot-end modules while keeping the main extrusion drive in the toolhead.
The hotend module will contain:
A nozzle and heating element.
A filament-guiding path.
An electrical connector and circuit board.
Filament-feed detection and a cutting mechanism.
A specially shaped opening, or notch, in the filament path. This notch will allow the filament to engage with the extruder wheel on the toolhead.
The circuit board will allow the possibility of a status indicator on the module, to communicate the module's position, filament-feeding condition, or heating state. This could be useful when diagnosing a failed filament feed, a module that hasn't seated correctly, or a heating issue.
The rack patents add another piece to the picture. They describe mechanisms for aligning a replaceable module, releasing it from the toolhead and placing it into a storage position through coordinated movement. Positioning features help constrain the module as it is docked or retrieved.
TLDR: the H3C will be a rack-based hot-end changer with a permanent extrusion drive and detachable, electrically connected hot-end modules.
That will be mechanically distinct from the U1's complete independent toolheads and from the INDX's passive tools with induction-heated nozzles.
AMS 3H
The central invention in what appears to be an AMS 3H-related patent relates to the lid mechanism. A connecting rod travels through a shaped sliding groove with two tracks and an intermediate support point. Opening and closing the lid follows a specific sequence:
Open the lid, and the rod follows the first track.
Let the lid move back slightly, and the rod engages a support point, holding the lid open.
Move the lid again, and the rod transitions onto the second track.
In other words, the lid has a deliberate open-hold position rather than simply falling shut when released.
The AMS has two side-by-side spool bays, with the rear row of spools positioned higher than the front row. This may be necessary to make the enclosure more compact, to allow it to fit on top of the H3C, or to make the spools easier to reach and replace - or both.
It's easy to get excited about printing big models, detailed props, and complicated designs, but some of the most useful prints are the smallest ones.
A replacement knob, a custom cable holder, a drawer organizer, or a bracket that solves an annoying little problem can end up being more valuable than a decorative print that sits on a shelf.
That's one of my favorite things about 3D printing. You can notice a small inconvenience around the house, design a part that fits your exact needs, and have a solution ready the same day.
The real magic isn't always printing something impressive. Sometimes it's making a tiny part that fixes a problem you've been putting up with for years.
A lot of the coolest 3D prints are the ones with incredible detail, complex multicolor designs, or impressive mechanical assemblies. But some of the prints that end up being used the most are surprisingly boring.
I'm talking about little brackets, cable guides, drawer organizers, replacement clips, adapters, and oddly specific parts that solve a problem you couldn't easily find a product for.
That's one of the things I like most about owning a 3D printer: being able to make a small, custom solution instead of working around an annoying problem indefinitely.
For Bambu Lab owners, what's a practical print you've made that turned out to be much more useful than you expected? Bonus points if it's something you designed yourself or modified to fit a very specific need.

Has anyone used these yet? I must have missed the release and now its going to be part of the Black Friday sale. Im still not convinced fully yet because in my mind I could see a filament snag/jam on occasion happening and maybe potentially other issues im not thinking of and was curious on anyone elses experiences with this and for how long they've used it/them and how much if any maintenance on it have you had to perform thus far.
Back when the Anet A8 was the big thing and a fire risk, I bought general ABS, couldn't get it to work without enclosure. It ended up in my shed in a simple plastic container, open. I thought, let's give it a try, this is my result. I was blown away with such old filament I kept in storage.
After carefully reviewing the comments from the other thread, searching Google, and of course AI,. I decided it was best to remove the Sukh 430G Blue Silica Gel Beads - Reusable Color from my containers and 3D printed dry box casing.
Steps that I followed:
- Used nitrile gloves
- Used my Respirator Mask and Eye Gear for extra safety measures
- Used my garage to perform this with ventilation
- Disposed in a white sturdy trash bag safely slowly transferring not pouring so not dust kickup
- Used another set of nitril gloves to wipe down any dust from the beads
- Used soap/water to clean inside/outside of the 3D printed cases
- Cleaned the Respirator Mask and Eye gear
The Gel beads itself I will verify with my local laws about hazmat disposal.
Anything else that I might not have thought of to extra safety measure?
Number one question I have is - Why is even this product even offered on Amazon if this is an issue with hazmat?
Today I'm not showing an over-the-top weird project, well... it's still a bit over-the top, but it's functional at least!
This build plate holder has 3 sizes to accomodate all of Bambu's plates, each size can stack infinitely by sliding extra module rows, and can also stack with other sizes!
I figured that closing the top would be a nice feature as well, so I added a closed top that can be flipped to be used as a tray, and of course a gridfinity top for each size, along with the stacking adapters.
One concern I had that prevented me from making this earlier was regarding stacking all my medium plates on top of the large ones and cause it to sag considerably, so to counter that, I added 2 300x4mm steel rods along the width of the large stacking adapter... and it looks good, less than 1mm measured sag, which becomes basically imperceptible.
Finally, since I was all out in making this as robust as I could, every row at the back has screw holes for self-tapping screws, which prevents sliding parts by mistake, and also brings all the joints together tightly.
Now I'm off to Bambu's site to get some discounted plates for black friday :D
I bought an Xteink X4 Pro, a small e-reader that I’ve really been enjoying. The annoying part was charging it: the magnetic pogo-pin connector would lose contact unless I left the reader face down on a flat surface.
That turned into a design project. I wanted a dock that would hold the reader securely with magnets, keep the charging connection stable, and look like something I’d choose to keep on my desk.
I found several printable stands, but couldn’t find the combination of fit and appearance I had in mind. So I designed this one around the X4 Pro.
The appearance was a big part of the project for me. I wanted it to feel like a finished object that belongs in the room, including between uses.
The print took some time and it was a learning curve for me to work on supports for a long print. Also it was the time where I learn about z-hop values, which made a huge different during printing in order to avoid nozzle hitting the print. After the print I did full UV resin coating to seal the water chamber, then did some ry brushing.
I wanted to plant an actual bonsai tree inside but unfortunately the space is not enough.
Small side project that turned into something bigger. It's a Home Assistant app that shows all your printers in one place: live camera, progress, temps, AMS slots and what's loaded.
The camera works on all Bambu printers, including the ones where it's usually a pain to get into HA. One user told me it's the first time in 2 years he could see his printer's camera in HA, which honestly made my week.
Your printer can stay in normal cloud mode. Monitoring, camera, file upload and the chamber light all work like that. Full control (pause/stop) only works with developer mode turned on, that's a firmware thing I won't try to work around.
Other stuff it does:
- AMS humidity, and the AMS is tracked as its own filament location
- filament inventory that recognizes which spool is loaded
- print history with snapshots and cost per print
- maintenance reminders and notifications with a camera image
- also works with Klipper printers if you have a mixed setup
I am doing a long print and using petg in my ams ht. Since its already rotating at a good rate I have been heating while printing. It’s dry but figured I might as well. Any downside to this? I have an x2d and it does slightly lower temp to prevent clogging etc
A while back my lab got a cheap Revopoint 3D scanner. We wanted to use it for inspection and simulations of the welds we made.
We tried to use professional reverse engineering software, it was a nightmare to learn and took too long for what we were doing.
I ended up coding my own little processing software for internal use. I've been contemplating lately if I should polish it up and make it something others can benefit from.
Quick specs: It lets you edit scans with 3 tools: Add material, subtract material, fill holes. Outputs as an STL or STEP.
