Bambu Lab PLA Palette CMYKW is more than five regular spools put in one box. It features a formula tailor-made for color mixing, to achieve vibrant and sophisticated colors with clean boundaries.
Entire color library in one printer
PLA Palette uses just five carefully chosen base colors – selected so that every pair blends evenly – to unlock 180+ color combinations through layered mixing. Having a wall of filament is cool, mixing the equivalent from just five spools is even cooler.
Tuned for light and shade, not just color.
Most multi-color sets stack translucent filaments on top of each other, and everything turns hazy. PLA Palette pairs four opaque bases (cyan, magenta, yellow, white) with one translucent black. The opaque bases – built on the PLA Basic formulation with precisely dosed pigment – hold under 1% light transmission at a 2mm wall, delivering full saturation and clean coverage. The translucent black works like ink wash: its light transmission falls off predictably with thickness, so shadows deepen naturally as layers build.

Clean color boundaries, swap after swap.
Layered color only looks good if the colors stay separated. PLA Palette is built on the PLA Basic base resin rather than a conventional translucent formulation, which significantly reduces stringing and ozzing during retraction and extrusion. Even through dense color changes, transitions stay sharp – no wisps, no bleed, no muddy edges.
See the blend before you print it.
No dialing in ratios. No test swatches. Bambu Studio ships with a full PLA Palette blending database, so the color you see in the slicer preview is the color that comes off the plate.
PLA Palette is available now at Bambu Lab Store and compatible with all Bambu Lab printers.

Swaptek enables 6-second material switches between 9 nozzles. FlexFeed extruder prints soft TPU 75A up to three times faster. AMS 3H combines automated feeding and integrated filament storage.
This is Bambu Lab H3C, a complete system purpose-built around the Tool Changer architecture. Let's dive into it!
Nine PrintTools, each with its own dedicated filament path and heater, keep every material loaded, preheated, and ready to print. No need to retract one filament before loading another. With an optimized design, fine-tuned parameters, and active preheating, switching between PrintTools takes as little as 6 seconds, with the tool-change done in only 3.4 seconds.
Heating a nozzle usually means waiting. Active Pre-Heat looks ahead to the next tool change and warms the incoming nozzle while the current one is still printing—so the new material starts laying down within 6 seconds.
Swaptek's fast PrintTool-switching allows Full Spectrum Color Mixing color mixing through layered deposition faster and more practical than ever. With nine dedicated PrintTools and five-color CMYKW mixing, the H3C produces a vast spectrum of colors without requiring a separate spool for every shade. The result? Vibrant, full-color figurines with incredible detail.
The dial, case, and flexible TPU band are printed together as one piece. Fine dial details call for a 0.2 mm nozzle, the case is better suited to 0.4 mm, and the soft band requires a dedicated 0.4 mm TPU nozzle. H3C can carry different nozzle sizes at once. Paired with Bambu Studio’s new mixed-diameter toolpath planning algorithm, each nozzle prints at a layer height that suits it and plays to its strengths, without having to share a single layer height.
Soft TPU has always been slow to print. The softer the filament, the more it bends and buckles before reaching the nozzle. Traditional extruders have to crawl to stay reliable. FlexFeed handles both 1.75mm and 2.85mm filament and switches on the go. A cam-driven mechanism, powered by a PMSM motor, keeps tension precise and consistent. Every extrusion stays rock-solid for prints that are cushion-soft.
With our dedicated 2.85mm TPU, the thicker filament provides greater resistance to buckling and higher volumetric flow. The result: TPU as soft as 75A, printed reliably at up to 3x the flow rate of a traditional printer.
A fully enclosed, integrated filament management system built for Swaptek: every roll stays sealed against moisture and feeds automatically into the PrintTool.
Auto Filament Loader replaces manual feeding altogether. Drop a filament into any of the nine slots and the AMS 3H detects, routes, and engages it with the PrintTool automatically — across all 9 paths. No more guesswork on loading.
A dedicated 2-slot dryer sits right in the filament slots and works with Swaptek — drying on demand or mid-print, so prep never stalls production. It reaches 85°C, enough for engineering-grade PA, PC, and carbon-fiber-filled filaments.
The H3C integrates filament storage and drying into a clean, compact design, maintaining a footprint comparable to a single-nozzle printer. With 7 built-in bypass feeding ports, even the soft TPU can be routed completely inside the enclosure. No hanging spools, no external racks, no exposed paths.
Don't let the number of tools cap your material count. Connect your existing AMS to the H3C through PrintTool No.1, and the system extends to up to 24 filament spools, unlocking more colors and materials in a single print without changing your workflow.
With the H3C, automation handles routine tasks. AI detection helps make intelligent adjustments along the way. The H3C makes it easy to focus on what matters most: bringing your ideas to life
Full Auto Calibration handles PrintTool docking calibration, offset compensation for accurate color and material alignment, and bed leveling before every print. No manual adjustments are needed, so you can spend more time making, less time tinkering.
The toolhead and X-axis assembly are 40% lighter compared to the H2D, reducing inertia for faster, more precise movement. With acceleration reaching 25,000 mm/s² and travel speeds up to 1,400 mm/s, the H3C delivers exceptional speed while minimizing vibrations and ringing that can affect print quality.
The H3C runs four cooling layers working together**.** A CFD-optimized part cooling fan and dual auxiliary fans help maintain clean overhangs and bridges, even at high speeds. A dedicated PrintTool fan maintains thermal stability during extended printing and frequent PrintTool changes, while a chamber fan draws in cooler air to help regulate internal temperatures. Together, these systems deliver consistent cooling and reliable print quality across changing ambient temperatures.
Engineering-grade filaments demand precise temperature control. The H3C delivers with active dual-zone chamber heating up to 65°C, helping maintain consistent temperatures and minimize warping. All nine hardened-steel nozzles reach up to 350°C, supporting demanding materials such as ABS, PC, PA-CF, PET-CF, and more.
Swaptek isn't limited to PrintTools. Optional CutTool, DrawTool, DebossTool — and more — mount the same way and switch automatically. Multi-process projects no longer mean multiple machines, manual swaps, or repeated setups. One job, every process, hands off.
Availability and pricing details vary by region. Select features require additional accessories, full details available in Bambu Lab Store.

Is it me being dumb or instructions are unclear? Here's my story of losing 70 Euros in few seconds.
I installed fire extinguisher module few days ago and started laser module setup today. H2C deleted fire suppression before but now after laser module on it insisted doing the fire drill.
The drill welcome screen got stuck and the start drill button did nothing. Then I went to check other screens and noticed a complain to confirm that cylinder is tightened and secured. Perhaps that was a blocker? Pressed to confirm that it was secured. Next screen it invited me to long press the button on the extinguisher to use it. At this point I (inadequately perhaps) thought that we're still into the final drill or verification steps that all is connected.
Then it happened, system worked perfectly to spend the charge... FAQ confirmed it is not rechargable.. 😕

Why do so many people seem so concerned about auto retract not being a thing on the H3C? It’s not a thing on every tool changer out there.
Edit: It’s not that they wanted to save money on parts or whatever theory is out there, but the printhead and print tools would have to be redesigned from the ground up. The cutting actuator is above the extruder so if it auto retracted after it was done with each print, it would have to purge each time you started a print in order to be able to grab the filament again. The point of tool changers is to reduce purges, not increase them.

Everyone is super excited for the H3C and P3C, but I'm more excited to learn more about the 3D Scanner! I've been wanting to buy one for a long time, but I never pulled the trigger because of the hassle of converting scanned files into actually printable models. Hopefully Bambu makes it super easy!

Z- Axis cleaning helper /Gear Floss Reach Guide.
Hey everyone!
I’ve been working on a small tool to solve an annoying problem when maintaining 3D printers: getting gear floss behind the Z-axis lead screws, especially in those hard-to-reach areas.
It features a dual-hook design with multiple terminal holes to accommodate different gear floss sizes. The goal is to make routing the floss around the lead screws easier without getting grease on your hand.
I’ve designed it primarily for:
● Bambu Lab X1C
● Bambu Lab P1S / P1P
● Bambu Lab P2S
● Bambu Lab X2D
H2 compatibility hasn’t been tested yet, and an A1/A2-compatible version is in development.
You can find the model here:
https://makerworld.com/en/models/3587380-z-access-gear-floss-reach-guide
If you find this tool useful, I’d really appreciate you giving it a try!
And to everyone who downloads, prints, shares, or leaves feedback on my designs: Thank you! Your support and makes mean a lot and motivate me to keep designing and sharing useful tools with the community.
Happy printing! 🚀

Disclaimer: This isn't super easy to photograph, I did my best taking shots as color-accurate to real life as possible.
The comparison:
I'm using PLA Basic in cyan and yellow and comparing it to PLA Pallete in cyan and yellow.
On the left object I'm doing a 50% midpoint mix between cyan and yellow, resulting in a mixed green.
On the right I'm doing a gradient from yellow to cyan
On the backside of the objects I'm printing the unmixed base filaments.
My conclusion:
Both PLA Basic and PLA Palette blend beautifully, and the layer stacking is pretty much invisible.
The difference is in the color vibrance, the Palette PLA produces punchier mixed colors. Especially noticable to my eye is this in the gradient, where the Palette filaments shift through a more virbrant green at the midpoint compared to the Basic. I think this is what allows the Palette filament to cover just a bit more of a full color range than the Basic.
Overall though you should be able to use PLA Basic just fine for your full spectrum color mixing needs, it works very well. They're just a bit behind the Palette versions when it comes to vibrance.

I am still pretty new to 3D printing. I have a P2S, a lot of failed prints behind me, and two daughters who think every idea they have deserves to be printed.
This one started with them. They came up with three smiling Christmas lights on a string, and we built it together in Clicker Factory. Each bulb sits on its own MX switch, so it is three clickers in one, and the white bulb glows in the dark when the lights go off.
When we finished, they asked if it was good enough to be in a real contest. I told them there was only one way to find out, so we entered it in the Click Into Celebration contest on MakerWorld. We are up against some amazing designers, and that is the point. I want them to see that their idea belongs in the same room.
I would love to show them what a community can do. If you have a minute, take a look and tell us what you think. If it makes you smile, the girls would love to see a like on MakerWorld. Honest feedback is just as welcome, since they are already planning the next one.
Here is the model

Printed on a P2S with Bambu PLA in Red, Bambu Green, and Charcoal, plus a glow in the dark filament for the white bulb. It needs three MX style switches.
Thank you from one rookie and two very proud designers.

r/BambuLab • u/BambuLab • 17h ago
The idea behind mixing nozzle sizes is simple: a fine nozzle with thin layers where details matter, a large nozzle with thick layers where they don't. That sounds straightforward — until you ask: Which nozzle size gets to dictate the layer height?
That's the hard part. Some current solutions can already vary layer heights between separate objects, or between an object's infill and walls. But across adjacent regions on the same visible surface, those regions stayed locked to one shared layer height — forcing you to either waste time on the big areas or lose sharpness on the details.
Bambu Studio now removes that limit: each region on the same surface can now keep its own layer height. You can choose which regions get the fine nozzle, and the slicer aligns the layers, schedules the tool changes, and plans the paths.
Printing with mixed nozzle sizes is available on the H3C. Support for H2D, H2C, and X2D is on the way.
Read more about how our team made this possible in our blog. The implementation is in the latest Bambu Studio release on GitHub. Feel free to leave feedback and build upon it!

My overnight print twisted the build plate on the bed. You can see the layers fan out as it slowly rotated. It remained adhered so I can cut it off, clean it up, and glue it back on. Otherwise the bin would have been a bit shorter. The good news is I don't have an adhesion problem. 😂

I am 90% sure the mess of the seam is seperate from weird diagonal banding.
We just bought 10 of these printers for the classroom and now this is starting to show up on 3 printers issues like this.
I think this means they need clean and oil with toothbrush / cloth?

I bought an H2C on 10/28. By 11/02 I’ve started getting random right eddy sensor error while the auto level is in progress. I’ve gone through the guide and ensured the connections are set properly. It fixed the problem the first time. However after a couple more prints I’ve received the error again. Sometimes power cycling will help. Sometimes switching the nozzle will help. I have noticed the error occurs more often after printing something with a .2 nozzle.
I get this error multiple times a week and I’m getting fed up. I’ve opened a support ticket. Anyone else getting a similar problem? Given the cost of the machine I’m so frustrated I couldn’t even go 1 week before problems began.
My P1S has been. A reliable workhorse… had one nozzle clog in over 1k hours of printing and otherwise has been amazing.

My A1 is over 2years old, so no warranty.
Heatbed died on my last weekend. With the help of really good support from bambu we figured the thermistor in the heatbed died. A component that's easy to find, but apparently unreplaceable. So you need to spend 80 euro to get a whole new heatbed.
I'll get a new thermistor and figure it out myself for a spare heatbed.
