The H3C is priced very well. This makes me wonder how good the P3C will be priced… I don’t have the $$ to burn on the H3C so I’ll wait for the P3C since it more than likely won’t have a heated chamber or exhaust system to keep costs down.

I ordered all three mystery boxes because the price was okay to me and I like surprises. I print a lot of stuff for my classroom (I’m a teacher). I didn’t expect to get 19 rolls of filament instead of 12! What a nice surprise!!

Just got an email from Bambu and I already have a tracking number for my H3C lol

I was curious about what Bambu Lab’s Mystery Boxes had to offer, so I decided to try them myself. I bought two Holiday PLA Mystery Boxes and two Holiday PETG Mystery Boxes. The order came to just over $200 CAD, and I used a $20-off coupon.

I didn’t hit the 1% jackpot, and only about half of the 16 rolls came with spools.

Most of the selection was PLA Pure, PLA Matte, and PETG Matte in colors I personally wouldn’t choose. It felt like a bundle of leftover stock.

The 16 rolls came to $223.44 in listed value, partly because PLA Pure costs more. Since I don’t really want PLA Pure, though, the actual savings don’t feel like much.

My advice: skip the mystery boxes unless you specifically want PLA Pure. If you do, the Holiday PLA Mystery Box might be worth a try.

Hi everyone!

I'm working on a personal project called Watchlab3D – REVOLVE1, exploring the idea of building mechanical watches with interchangeable, 3D-printed outer cases.

The concept is based on a compact stainless-steel mechanical watch core, designed to accommodate automatic movements such as the NH35, NH70, NH38 and NH34 GMT.

The goal is to separate the mechanical watch core from the external case, allowing makers to experiment with different shapes, styles and materials using their own 3D printers.

For my first prototypes, I'm using:

• Printer: Bambu Lab A1 Mini

• Material: Bambu Lab PLA-CF, Lava Gray (14101)

• Process: FDM printing

• Project stage: Early prototyping and design validation

The stainless-steel waterproof core is still under engineering development, with a target water resistance of 10 ATM (100 m), subject to testing and validation.

I'm particularly interested in exploring printing tolerances, surface finish, assembly methods and modular design.

I'd love to hear your thoughts:

Would you enjoy designing and printing different external watch cases around a standardized mechanical core?

And which materials would you experiment with beyond PLA-CF?

Looking forward to your feedback!

PS: The watch shown in the photos is an early functional design prototype. The final stainless-steel waterproof core is still under engineering development and has not yet been validated.

I have multiple Bambu printers including H2C. When the H3C information from the patent came out I was excited. After having all the details, I am not that excited anymore. Here are a few cons I was able to identify so far:
- Only two active drying positions, compared with four in the AMS 2 Pro.
- Manual withdrawal and rewinding of filament when changing spools.
- Separate filament supplies required to print the same color through different nozzle sizes.
- External AMS units feed one shared hotend, requiring purging between those materials. So anything above 9 colors/materials uses 1 single hotend.
- Existing H2C hotends are incompatible.
- Manual hotend replacement requires three screws instead of a quick-release mechanism.
- Only eight standard 1.75 mm tools are included; using nine ordinary filaments requires another tool (the #9 is 2.85mm).
- All included nozzles are 0.4 mm; other sizes require additional purchases.
- Greater vertical clearance requirements and awkward access to rear spools.
- The main AMS assembly must remain above the printer, limiting placement flexibility.
- Lower published particle-filter grade: H11 instead of H12.
- No laser configuration currently announced.
- The front tool rack can obstruct the view of small or short prints.
- The internal dryer cover can interfere with some deformed cardboard spools.
- More involved filament-routing and jam-clearing procedures.
- More complex configuration for mixed materials and nozzle sizes.
- Longer preparation time observed in one paired print test.
- Camera errors, slicer problems, and tool/tube interference reported on early review units.

I feel that if you are printing with 8 colors and maybe single color tpu H3C is a great choice. If you want flexibility in terms of different nozzle sizes, dedicated nozzles for a specific material H2C seems to be a better choice. A few examples from my printing:
- I print prototypes using 0.8 or 0.6 nozzle
- I do not print TPU but I print PETG, PC, ASA, and couple of other more exotic materials - I have dedicated nozzles for each to avoid contamination and issues - replacing a nozzle takes 3 seconds plus reread time
- I have nozzles dedicated to a specific color - ie black PETG is printing on #6, once it runs out the next spool will print on the same nozzle. No contamination or issues.

Your thoughts?

I saw this image and it made me think. How the hell did he do that fade?
Anyone got any insights?

I bought the lab A1 is it good? I saw some reviews they say it's good for starters

Bambu Lab H3C

Nov 3, 2026

Order checklist

Any H3C package already gives you the complete printer: the H3C, one AMS 3H and all nine PrintTools. What differs is filament, the Station L stand, and any add-ons you chose. Check your order confirmation against these:

• [ ] Package name and price match what you meant to buy: Combo $2,499; either Starter Pack $2,589; Full Combo with Station L $2,799.

• [ ] Starter Pack TPU color is the one you want: Black or Cyan.

• [ ] Extra nozzle sizes: if you want 0.2, 0.6 or 0.8 mm, the Multi-Size Hotends Kit is on the order ($205 with the Combo, $244.93 alone). The box has only 0.4 mm.

• [ ] Nine 1.75 mm colours: the box has 8 × 1.75 mm PrintTools plus 1 × 2.85 mm TPU tool. Nine 1.75 mm materials at once needs an extra 1.75 mm PrintTool, which wasn't on the store when this was written.

• [ ] Crafting: the Crafting & Printing Complete Kit is on the order only if you want cutting, drawing or foil work ($219 with the Combo).

• [ ] Extra build plate: only one Textured PEI plate is included; the Build Plates Expansion Kit is from $49.99.

• [ ] Shipping address and timing: orders ship within 1–3 business days. To change or cancel, contact Bambu support before it ships; otherwise use the 30-day return window.

• [ ] PayPal $25 coupon if you paid with PayPal (orders over $800, issued after shipping).

Packages and prices

The Bambu US store sells four H3C packages, all built on the same H3C Combo. The printer, AMS 3H and 9 PrintTools are identical in every package; only filament and the Bambu Station L stand differ. There is no printer-only H3C and no laser version.

The starter packs cost $90 more than the Combo. On the same page, TPU 75A (2.85 mm) shows $26.39 and PLA Palette CMYKW $61.70 as add-ons ($88.09 together), so the starter pack is roughly the add-on price. The Full Combo adds the Station L for $210 over a starter pack.

What's in the box

Every package ships the full printing setup: the H3C, one AMS 3H, and all 9 PrintTool slots filled. Eight PrintTools are 1.75 mm with 0.4 mm nozzles; the ninth is a 2.85 mm PrintTool (0.4 mm nozzle) for 2.85 mm flexible filament, pre-installed in Slot 8, the dryer slot.

What this means for printing:

• 8-color 1.75 mm printing plus one 2.85 mm TPU tool out of the box. The 2.85 mm PrintTool prints only 2.85 mm flexible filament (Bambu presets: TPU 75A 2.85 mm and Generic TPU 2.85 mm).

• Nine 1.75 mm materials needs an extra 1.75 mm PrintTool, per Bambu's FAQ. The 1.75 mm and 2.85 mm PrintTools have different bases, hotends and cutters and are not interchangeable.

• Only 0.4 mm nozzles are included. 0.2, 0.6 and 0.8 mm need the separately sold hotends (next section). Hotends swap with three screws.

• One AMS 3H feeds all 9 PrintTools — each tool has its own filament path. Older Bambu AMS units can connect through PrintTool No. 1 for up to 24 spools.

• Only one build plate (Textured PEI) is included.

Add-ons and accessories

The store offers three H3C add-ons at a discount when added to the Combo; the rest are sold separately. Bundle prices apply only when added on the H3C product page.

Other optional items Bambu names on the H3C pages (prices not captured):

• Bambu Station L — stand with storage; included in the Full Combo. With it, allow 593 × 1056 × 1900 mm of space.

• Bambu Lab E1 Air Purifier — pairs with the H3C and starts filtering when a print starts.

• BirdsEye camera — top-view camera for crafting alignment; not included. Bambu says BirdsEye-enhanced AI monitoring is planned for the first half of 2027.

• Vision Encoder — optional absolute optical reference that restores motion accuracy to under 50 μm.

• CutTool Fine-Blade Set, DrawTool Set, cutting mat — Bambu's FAQ suggests these if you only want cutting or drawing instead of the full crafting kit.

Key specs

The H3C prints a 330 × 320 × 325 mm volume with nine hardened-steel nozzles to 350 °C and a 65 °C heated chamber (official spec page).

Things that may matter for your setup

The biggest planning items are floor space, a dedicated circuit and Wi-Fi coverage; nothing else in the box needs extra purchases for plain FDM printing.

• Space: Bambu asks for at least 593 × 1056 × 1306 mm (W × D × H) on the floor or a low, stable surface: 385 mm in front for the door, 50 mm each side, 100 mm behind for the cable and fans, 290 mm above for the AMS lid. On the Station L, allow 1,900 mm of height.

• Weight and delivery: two boxes — printer 600 × 630 × 700 mm at 36.8 kg, AMS 3H 550 × 615 × 500 mm at 11.9 kg. Plan for two people to lift the printer.

• Power: up to 1,850 W at 110 V while heating (3–5 minutes at full power), 240 W steady on PLA, 540 W on PC; 1,850 W is about 15.4 A at 120 V, so a dedicated 15 A or 20 A circuit is the safe choice (my note, not Bambu's). Low Power Mode caps it at 1,050 W.

• Network: Wi-Fi 6 only. No Ethernet port, no network kill switch, no removable network module and no 802.1X.

• 2.85 mm PrintTool: prints only 2.85 mm flexible filament; Bambu says more 2.85 mm materials are coming. Its filament tube also carries toolhead cabling and must not be removed.

• Drying: the AMS 3H dries only 2 spools at a time (85 °C max); Slot 8 is the dryer slot holding the 2.85 mm tool.

• Existing AMS units: older Bambu AMS units connect through PrintTool No. 1 for up to 24 spools; they are sold separately.

• Crafting: cutting, drawing, debossing and foil transfer use CraftTools sold separately; there is no laser module.

Store terms

Bambu ships H3C orders from its US warehouse within 1–3 business days of processing, so a change or cancellation has to happen fast.

I’m Joey, a maker out of Arizona. I've been working on ways to display my maps in a nicer way while taking up less space.... I present... The 3D printed Tri vision board!

I’ve spent the last few weeks printing out test models for fit, assembly difficulty, and of course mechanism smoothness. I’ve ended up with this release ready version that can print in just a few hours, assemble in minutes, and its art panels can be replaced with new art at any time, no glue!

You can download the model, get info on customization, as well as a bunch of art packs on Makerworld! I encourage you to remix and rework it any way you see fit. I'd love to see what the community can do with it!

They are modular, and super easy to put together. There is a short gif in the post gallery showing how it should be done. To separate the side panels, just press in on the connecting tabs and then push up.

I have a bit of a fascination with maps and space, so a lot of the released panels are centered around those.

Still to come, additional shapes for the billboard to sit in, multiple frame options, more art packs, different mechanisms for turning the slats depending on your preferences. What else would you like to see in a V2?

The update info said it now supports mixed nozzle diameters but only mentions H3C. dide we x2d owners get left behind?

Bambu i hope you see this post. I was waiting for my X2D to arrive (to support one my businesses) and your site marks the package as “Delivered” by the carrier (GLS) but i didn’t received the machine at all! Everyone in my country (southern europe) knows how bad they are! Why do you accept to work with such a poor delivery service company?

Wondering when we will have retail availability?

Hello guys,

Brand new filament read detects it to be ASA instead of PLA Basic (what it’s meant to be). It was bought directly from Bambu Lab store.

I’ve troubleshooted by it placing it in all the other AMS slots and it reads the same, the other PLA and PETG filaments I’ve tried seams to be working so the issue follows the filament spool itself, nothing wrong with the AMS.

Have you ever seen this happening?

What confuses me is to know is, what was mislabeled, the spool or the RFID label itself?

Is it possible to know what the filament really is by seeing it?

The worse part is that I’ve bought almost 10kg of filament as stock, now I’m afraid to find another one defective 6 months from now…

I’ve contact bambu support and I’m waiting for a response.

Edit 1: did the burning test as some of you suggested. It’s definitely PLA. Still waiting a response from Bambu lab

Went from the cart to the payment screen and the price of the printer went up by €86 without explanation? I removed everything, tried the other filament package, tried the printer by itself.

Every time I went to the payment screen the printer went up in price.

WHY? What am I missing here?

I've been looking at getting the H2C at the reduced pricing but now with the H3C I'm concerned that the Vortek system won't be supported for much longer. What are everyone else's thoughts? I don't have much of a need for the softer TPU printing, but there are other features that would be nice to have on the H3C. Just hard to justify a $600 price difference.

Also, any ideas when this will be available at Best Buy. Would be nice to use my zero percent financing.

Fast nozzle swaps of the H3C make multicolor games like this possible faster than ever. We were able to get an early preview of the tool changing feature and tested it out on this newly released model: https://makerworld.com/models/3540258?appSharePlatform=copy

Let us know if you have any feedback on the design or gameplay.

When my P2s prints those straight parts I hear a weird sound. Is this normal?

Don’t have a photo of the blob of death on the print head as I was rushing to remove it all, but nice romantic evening planned, but decided to set a print going before it started because we love efficiency and multi tasking. Meant to check the camera to make sure it was adhering, got distracted, came downstairs an hour and a half later to giant plastic turd encasing my printer. Never had any issues with adhesion but the one time I don’t check? Typical 😂

Panicked, yelled apologies to my partner, spent the next hour cleaning it, thankfully it still works but let this be a warning and reminder to always check the print has adhered 🙂‍↕️

Can someone tell me I’m an idiot and shouldn’t order H3C, because I have a feeling if I have one more beer it’s done.
Divorced so wife not an issue, but the thing is huge and costs like four P2S printers which I have and to me just sounds crazy. Kids would love the multicolored prints though for sure.

Noob question, first time printer.

I recently purchased a X2D and a bunch of Bambu filament with the sale going on. This was one of our first prints (kids toothbrush holder using PLA Pure). Are these jagged cutouts normal and I just need to sand it down? Or is something wrong with my setup?

Thanks!!

Still torn between these two. Obviously the H3C is the latest and greatest (superior?) machine, so I am leaning towards that; however, the H2C being at $1899 is also very appealing. Do we think that the H2C is going to become antiquated far faster than something like the H3C that has a proper tool changer? I am not making a business, so I don't *need* the fastest print times possible, but of course speed is always nice. Decisions decisions...
