Multicolor 3D printing has a dirty secret: waste. If you've run an AMS-style system, you know the "poop chute" — that pile of purged filament next to your printer after a colorful print. On some jobs, the wasted filament weighs more than the part itself. The Snapmaker U1 was built to fix exactly that, and it became the most-funded 3D printer in crowdfunding history ($20.6M from over 20,000 backers) on the strength of that one idea.
After the hype, the real question for a buyer is simple: does it deliver, and is it the right machine for you? Here's the honest breakdown.
What makes it different: a real tool changer
Most consumer multicolor printers (like Bambu's AMS) use one nozzle and swap colors by purging the old filament and loading the new one — every single color change. That's where the waste and the wait come from.
The U1 takes a different approach. It has four independent toolheads, each preloaded and pre-heated with its own filament. To change color, it physically swaps the whole toolhead (Snapmaker calls it SnapSwap). No purging a full nozzle, no reloading. A swap takes about 5 seconds instead of two minutes, and because nothing has to be flushed, the waste almost disappears.
The headline win: waste and speed
This is where the U1 earns its reputation. In real-world multicolor jobs:
- Waste: roughly 4 grams per 90 color swaps, versus 300–800 grams on a Bambu A1 Combo for the same kind of job. That's not a typo — it's a 50–100x difference on swap-heavy prints.
- Speed: color changes in seconds, so heavy multicolor prints finish noticeably faster. In testing it beat a Bambu P1P on multicolor work thanks to the instant swaps.
If you print a lot of colorful models, that waste reduction pays for filament — and your patience — over and over. It also shines with our brightest PLA+ and Silk PLA colors, where multicolor really pops.
The specs that matter
It's a genuinely capable machine underneath the gimmick-free headline: 270 × 270 × 270 mm build volume, a rigid CoreXY motion system, Klipper firmware (with Moonraker), and tight factory calibration (under 0.04 mm). Because each toolhead has its own heater, it also handles true multi-material — combining flexible TPU with rigid PETG in one print. Quality is clean and on par with the best in its class.
The honest cons
No machine is perfect, and a good review tells you where it bites:
- Hard four-color limit. Four toolheads is the ceiling — it's architectural, not a setting, and Snapmaker has confirmed there's no expansion. If you need 5+ colors in one print, this isn't your machine.
- Engineering materials are an add-on. ABS, ASA, and other high-temp filaments need the optional Top Cover (around $149–249), and even then the chamber is only passively warmed (~50°C). If your main goal is functional engineering parts, a printer with an actively heated chamber is a better fit.
- It's louder. Peaks around 65 dB, versus ~50 dB on a Bambu A1. Not ideal if it lives in your office or bedroom.
- Software is still maturing. Snapmaker's slicer (an Orca/Bambu Studio fork) works well, but the model library and material profiles are still catching up to Bambu's polished ecosystem.
- Support material costs a color slot. You can dedicate a toolhead to support material with clean results — but that's one of your four colors gone.
How it compares
If your priority is low-waste, fast multicolor and you live within four colors, the U1 is currently the most compelling option in its price range — nothing else cuts waste like a true tool changer. If you need more than four colors, high-temp engineering materials out of the box, or whisper-quiet operation, a Bambu (A1 Combo for simplicity, or the X2D/H2C for an active heated chamber) may suit you better despite the waste.
Price and value
At roughly $849 pre-order / $899–999 retail, it's strong value. Tool-changer designs used to cost far more, so getting genuine multi-toolhead hardware at this price — with the waste savings on top — makes the math work for anyone doing serious multicolor volume.

The verdict: who should buy it
Buy the U1 if you print a lot of colorful, multi-material models and you're tired of the waste and wait of AMS-style systems. For makers, small shops, and anyone selling colorful prints, the filament and time it saves add up fast.
Skip it if you need more than four colors per print, your work is mostly high-temp engineering parts, or you need a quiet machine.
For the right user, the U1 isn't hype — it's the first consumer color printer that makes multicolor feel practical instead of wasteful. See the U1 in our store →
