Three years ago, I told you how home 3D printers had evolved for speed, producing parts in minutes that used to take hours or days. Now, the next evolution is here: printers that can swap between materials on the fly, mix different colors to produce nearly the full rainbow, mix soft and hard materials, and even mix different sizes of nozzle and different diameters of filament so you can switch between high speed and fine detail in a single print.
Today, Bambu Lab is announcing its most advanced 3D printer yet, the $2,499 H3C, which can do all of that mixing goodness — by loading nine different rolls of filament into nine different print heads.
Even if you’d never buy a printer this pricy, even if you’ve sworn off Bambu printers for good, the H3C is the perfect vehicle for me to explain where the state of the art in home printing tech is headed.
While the H3C still only prints in one material at any given moment, Bambu’s new “Swaptek” system lets the printer swap in any of the eight other nozzles in six seconds flat. All nine tools are stored in a rack at the front of the printer, where they can independently preheat to the correct temperature right before they’re needed.
With Bambu’s new “PLA Palette” cyan, magenta, yellow, and white filament, I printed a beautiful rainbow bird feather that emulated most of the other colors between those inks. With a mix of flexible TPU and rigid PLA filaments, I was able to print a hard wristwatch housing with an integrated flexible watchband. With an ultra-soft “75A” TPU filament plus a harder 90A variety, I printed a breathable, wearable shoe that… didn’t quite fit, unfortunately. (I’ll measure and try again.)
To be clear, Bambu didn’t invent toolchanger printers or color mixing. You could even argue Bambu’s slightly behind the curve, particularly after the $700-$900 Snapmaker U1 and its four-color, five-second swaps pleasantly surprised the community earlier this year. (Prusa also sells its hotly anticipated 8-tool INDX system for $2,249, though I’ve heard it has some issues.)
But I would have never bought previous toolchangers for myself, because they don’t have a place to keep your filament dry when you’re not printing. (Wet filament is one of the biggest remaining causes of print failures.) The H3C theoretically changes that by storing its nine rolls in an ostensibly airtight auto-loading container called the AMS 3H. Two of those nine slots even have built-in dryers that can hit 85 degrees Celsius and keep on drying your filament while you print, a big step up from Bambu’s previous AMS systems.
I haven’t tried the H3C for long enough to tell you if it’s ready to buy, and I’ve definitely run into some quirks in my first couple weeks of testing. I’ve had to start every single print twice because the printer complains that its “toolhead camera” isn’t initializing properly, I once lost half a day of printing to a false-positive print failure detection, and the beta build of Bambu Studio provided to reviewers initially got confused when I tried to mix colors. (I’m told that last one will be fixed by launch, and Bambu eventually provided some troubleshooting steps for the toolhead camera close to embargo time.)
You also have to load flexible TPU filaments into the H3C manually, and I learned the hard way that not all of the printer’s nine slots can actually accept a roll of TPU without causing trouble. Slot #6 can load standard filaments, but if you load the flexible stuff, another printhead can snag it and cause a nasty jam:
This also isn’t a printer where you can quickly repair a nozzle without tools, or use previous-gen toolless H, P, and A series swappable nozzles. It’s an all-new system that involves some minor disassembly, and I’m not sure about Bambu’s decision to leave filament in the toolheads between prints where it might attract moisture.
But so far, this seems like an easier, more reliable printer than the two-nozzle Bambu H2D was at launch. Other than the Slot #6 TPU jam, which Bambu actually warns reviewers about in a section of the reviewer’s guide that I missed reading, everything I’ve tried to print has come out great so far — and without creating a mountain of little “printer poop” waste when I switch between colors! Dramatically reduced waste is one of the benefits of having extra nozzles.
With any luck, the future of 3D printing won’t just be for hobbyists willing to figure out which colors of filament they need to order before each and every project, or obsessives who store dozens of colors in vacuum-sealed bags. Instead, it should be more like today’s inkjet printers — an entire rainbow of color, ready to go at a moment’s notice. And hopefully without all the inkjet printer shenanigans, of course.
If you like Bambu’s toolchanger system, you probably won’t have to pay $2,499 for long. Certification filing leaks show that the company’s already prepping a smaller “P3C” with seven tools and seven rolls of filament storage instead of nine.
Additionally, Bambu will let all three of its existing dual-nozzle printers print with two different sizes of nozzle by next spring, including the H2D, the H2C, and the X2D.
