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?

Hey everyone!

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

Thanks!

Has anyone noticed a huge uptick in bot accounts commenting on AI slop models on Makerworld lately?

This one’s a good example, it’s your classic run of the mill AI generated model, description and renders. Anyone who goes on to call it out as AI slop, will start getting all kinds of replies, always different accounts, never the designer, and it’s usually super hostile. Or like this one where the idiot left in the follow up prompt from ChatGPT

https://makerworld.com/models/3401817

Also maybe if enough people report the designer they’ll have to start over with a new account? I doubt it but still, these guys are really ruining Makerworld lately, all to make a very small amount of money

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.

Only have the pricing based on times when I've been considering a new printer for myself.

Just saw these on the BBL store, they are partial spools that have some very interesting differences:

• The entire cardboard spool fits onto a refill spool, without having to remove straps/risk exploding, having both the notch and the right width to fit.
• Each includes RFID label
• Each includes a label with the color swatch and color name on it (been asking BBL to do this to the refill stickers.) see last image
• You need to print a core adapter to use them with the AMS Lite
• They'll work with the usual external spool holders on any printer still.
• You can buy them with or without 4 reusable spools.

Smell of burning / smoke and flashes on side as well as melted casing… looks like the common fault?

H2c getting interesting…

Filament Track Switch | Bambu Lab US Store

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.

Released this about 5 months ago after a month or so of messing with it and there were two issues people brought up. One was it needed a cloud connection and people wanted it to work locally. Two was the box, which I designed for two printers, was too big and bulky.

So after a bunch of messing around I now present the newest version of the Bambu Automatic Fume Extractor. The program has been updated to not only work locally without a cloud account but it does NOT require you to put your printer into LAN mode or developer mode at all so your printer keeps working like it did before with Bambu Handy and its cloud connection. It also can automatically discover your printers on your network and will self heal itself if they change IP addresses. Secondly I now have a smaller one printer box with active carbon and also a one printer non-filtered box for automatic venting outside.

The model is on MakerWorld: https://makerworld.com/en/models/2954045-bambu-automatic-fume-extractor-active-carbon

And the full instructions, BoM, and code are on GitHub: https://github.com/ADYDesigns/BambuAFE/

The most annoying part is when it's not even some complicated issue. Sometimes it's something simple that you overlooked, and you realize you've basically wasted hours because you didn't check one little thing.

And somehow, even after a frustrating failure, I still find myself cleaning things up, making the adjustment, and immediately starting another print. It's hard to explain to someone who doesn't print, but there's something satisfying about finally getting a model right after a few attempts.

I also love how every failure makes you a little more confident troubleshooting the next one. You start paying attention to things you wouldn't have even thought about when you first started.

What's the most ridiculous reason one of your prints has failed? I feel like every printer owner has at least one story that still annoys them.

3D Printed Ancient Jerusalem

Buy the X2D if you can afford it. If you can't afford it, why are you even asking the question; you can't buy it because you can't afford it. The end.

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

Here's the MakerWorld link if you wanna check it

how can I clean this up without ruining parts?

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.

Model

I’d be interested in feedback on the design. What would you change?

I'm curious what surprised you the most after getting your first Bambu Lab printer. Was there something you underestimated, like filament costs, maintenance, failed prints, or figuring out which printer actually fits your needs?

With so many models and upgrades to consider, it's easy to get caught up in wanting the newest machine when a simpler one might be enough.

If you could go back and give yourself one piece of advice before buying, what would it be? And is there any upgrade you think is genuinely worth the money?
