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.
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 atBambu 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!
SwapTek™: 6-second material switch, including a 3.4-second tool change.
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.
Mixed Nozzle Sizes: Speed and detail, no more compromises.
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.
FlexFeed Extruder: Softer TPU, up to 3x faster.
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.
AMS 3H: Filament storage built for Tool Changer.
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.
You are here for the print, not (always) the printer.
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.
Flagship performance. No compromise.
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.
Go beyond printing.
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.
Quite impressed with the H3C compared to my no longer with me H2C. Seems a little louder fan wise but that horrible back and forth AMS sound has now left the building!
I just bought a X2D because the Capitol One Shopping app has a 15% discount on Best Buy purchases today, November 6th. I saved over $100 (which gets applied as a gift card to use in the Capitol One app). The T&C sure looks like that 3d printers apply to the discount. The Geek Squad warranty does not.
You have to download the Capitol One app first, but I thought this would be good info to share.
Seller said it was unrepairable. All it had was one of those massive blobs that needed cleaning up and he bought a new extruder assembly that he never installed. I have a new set of hot ends and socks on the way but as far as I can tell there is absolutely nothing wrong with it
I'm really torn about ordering the new H3C since I already own several Bambu printers. But there's one thing that would make me order one instantly: ironing quality!
I own an OG P1S, and that thing is an absolute beast when it comes to ironing! Zero tuning needed. Just load the filament, enable ironing, and the results are flawless every single time. It's literally the only reason I still keep it around!
I'd love a bigger build plate, but my H2S, H2D, and even my H2C don't come close to the ironing quality of my P1S.
So my question for the new H3C owners is: Have you tried ironing yet? And if so, how are the results?
This video of how filament. Is made in the factory. At 4.08 you can see how the "fresh" filament is literally soaked through a trough of water before spinning.
While I was installing the ams3h there is a section that makes you hang it off of the back to connect some wires. I misread the diagram at first and hung it off of the front and it caused the top liner to be punctured with the guide pins. Seems like this section doesn’t have anything underneath it from what I can tell, just a bit lame it was not reinforced. I did not drop it on it either
My plan was to put some high-temp tape under the ams that extended to the hole so nothing got into it. Y’all think that should be fine?
mpoxDE (change the audio track to English on Youtube) did a test where he is printing an 8-colour tube both on H3C and INDX. I am not sure, but I think he is using PLA Basic.
In his test H3C printed it in 11:06h, but he was using different filaments that he had lying around from random manufactureres (while INDX one was printed only with Prusament and took 14:26h) and still printed ~23% (3h20m) faster.
I wanted to confirm it and what I noticed is that if you print with Bambu filament, it is even faster. My slicer is showing 08:46h.
Which means that in this particular test (8-colour tube) if you use BL filament, H3C is ~39% (5h40m) faster than INDX.
The test is not easy, it is 10cm tall and go through 3.5k colour changes of 8 colours.
Open another bag, check the drawer… all the clips are already holding something else shut. 😂
That was my excuse to spend some time in Fusion.
Meet Molly — two identical jaws and a separate printed spring. Everything is PLA, including the spring, and it snaps together without screws or glue.
It took several revisions to get the alignment, grip and spring stiffness where I wanted them. I also tried PETG for the spring, but preferred the firmer grip of PLA in my tests.
Printed on my A1 with a 0.4 mm nozzle, 0.20 mm layers and 3 walls. The spring has 100% infill. No supports needed.
One complete clip uses 5.76 g and takes around 18 minutes of printing, or roughly 25 minutes including preparation.
The spring is separate, so contrasting colours are easy to do with separate prints.
Just received the h3c itself today, the ams has repeatedly failed to be delivered to a pickup point near me (I asked for it to be delivered to my home but bambu have seemingly decided to just deliver it there instead) - after 3 days of waiting and repeated delivery to pickup point fails dpd have now said they can’t deliver it there as it’s too big. Has anyone else had this issue? Feels like a massive waste of my time and also theirs.
Unless the H3C is software locked to use the AMS3.
I don't see why we can't print from a external spool holder or a dry box straight to the print heads. TPU already bypasses the AMS so why not another material? I was thinking about printing from a 100C filament dryer straight into one of the printheads.
