Aurora Tech does not mince words, summing up her video by concluding, "Should you back this project? My answer is a definite yes." She continued, "It makes multicolor and multimaterial printing practical, faster, and most importantly, it doesn't waste more filament than the model itself ... This could very likely become the #1 recommended printer on my list."
DukeDoks put the U1 through its paces to build a pair of incredible multi-color RC Car models: "It's the first toolchanger I've tried and I really loved the experience ... The truth is that I have fallen in love with it
Creative freedom has long been the promise of multi-color and multi-material 3D printing. The reality until now? Endless purging, wasted filament, and prints that should finish in a few hours taking all day. And mixing filaments, like PLA with TPU? Forget it—most printers can’t even try. Snapmaker U1 changes the game: skips purging delays, cuts excessive waste, and expands what’s possible in every print.
Most printers rely on filament changers to switch between colors or materials, spending more time purging than actually printing. With four toolheads preloaded and pre-heated with their own filaments, the SnapSwap™ system lets the U1 switch by simply swapping the toolheads, cutting your wait time from approximately two minutes to only five seconds[3].
Filament-changing printers "purge" by wasting perfectly good filament—pushing one color through the nozzle until the last trace of the old one is gone. The U1 doesn't play that game. It only purges the tiny amount of filament that's actually degraded by the time a new print job begins, or during flow-rate calibration, cutting waste by up to 80%[4]on every print.
The U1 uses steel-ball kinematic couplings to click each print heat into perfect position, then locks it securely—no screws, no magnets, no extra motors. Locked fast, rock solid, tested over 1,000,000 swaps with zero failures.
Based on SnapSwap™’s waste reduction, here’s your potential yearly savings.
With four independent extruders, the U1 lets you mix and match materials freely, giving each part its own function, or making support removal a breeze with low-adhesion combos.
With four toolheads working at high speed, precision isn’t optional—it’s built in. The U1's compensation algorithms lock every toolhead in sync, dampen vibrations, dial in extrusion, and level out the build surface, so you get the smooth, dimensionally accurate results you’d expect from a top-tier single-head printer.
The U1 automatically aligns XYZ offsets between multiple toolheads, keeping offsets within 0.04mm[5] for sharp prints without vertical shifts.
Input Shaping, aided by a precision accelerometer sensor, reduces vibrations caused by rapid directional changes by pre-processing movement commands to cancel out resonant frequencies. By adjusting acceleration profiles and introducing calculated delays, it prevents surface artifacts like ghosting or ripples, allowing the U1 to deliver clean edges, smooth walls, and sharp details even at high speeds.
The U1 uses Pressure Advance to stay ahead of flow delays, especially during quick moves or sharp corners. It tweaks extrusion timing based on motion changes, so filament flows smoothly even when speeds shift. That means fewer blobs, less thinning, and crisp, consistent detail.
The automatic mesh bed leveling delivers a flat, grippy first layer, setting the stage for every print.
The U1 comes equipped with a super-compact automatic filament system that holds up to four spools on standby. It handles everything from filament detection and loading, so you can print in vivid color, hassle-free.
Snapmaker Orca builds on Orca Slicer’s powerful engine and adds engineer-tested profiles for official materials and machine models. Paired with the Snapmaker App, you can start, monitor, and control your prints from anywhere—and even capture time-lapse videos to replay your creation in motion. Easy print management is right at your fingertips.
With a mix of over a dozen sensors and precision mechanics, the U1 automatically spots issues and guides you through quick fixes, ensuring smooth, successful prints every time.
The built-in chamber camera isn’t just for time-lapses. Starting with an OTA firmware update planned for December 2025 [6], its AI will detect spaghetti and workspace obstructions and alert you in Snapmaker Orca or the app, helping you avoid wasted time and material.
The U1 is built on a CoreXY motion system with lightweight, rigid carbon fiber X-axis rails, delivering travel speeds of up to 500mm/s and maintaining long-term precision across a 270 × 270 × 270mm work area.
Whether you're bonding over colorful creations at home, building your ultimate hobby hub, or adding a clever twist to your everyday style, the U1 makes it all effortless and fun.
*Note: Different Hot End sizes cannot be used in the same print.

Thanks for Being Part of the Snapmaker Journey
We would like to express our heartfelt thanks to the global maker community and to every one of our amazing backers who supported Snapmaker through our two previous Kickstarter projects—Snapmaker Original and Snapmaker 2.0. Your trust and encouragement have helped us grow from ideas into machines that now fuel creativity worldwide. Those journeys taught us not only how to design and manufacture better, but also how to listen, adapt, and keep raising the bar.
Here, we want to give our sincere thanks:
- To all Snapmaker users and backers—from putting your trust behind our vision, to sharing ideas, giving feedback, and swapping stories from your own making adventures. You’re the reason this journey keeps moving forward.
- To the incredible 3D printing community—from the creators of game‑changing tools like OrcaSlicer and Klipper, to our dedicated U1 test pilots, and every maker pushing the boundaries in workshops and garages around the world. Thank you for your passion, ingenuity, and generosity in sharing your knowledge. You’re the spark behind every idea we bring to life.
- To model creators —Creative Commons-Licensed models are the cornerstone of desktop 3D printing. They’ve enabled us to test prototypes, benchmark performance, and now demonstrate U1’s features. We attribute and honor all model authors featured on this page below:
With your support, Snapmaker U1 is here to bring high-speed, multi-material 3D printing within easier reach, making it dependable and a joy to use. We hope you’ll enjoy Making Something Colorful with the U1—whether it’s your next big project, a personal passion, or a long-awaited dream.
Our Commitment to Open Source
Here is the plan:
- We have modified and will release the following projects within Q1 2026: Klipper, Moonraker.
- We have used but not modified the following project and can open source it anytime: Fluidd (Web client).
Why not immediately? Because:
- We are still iterating rapidly, and opening too early could create confusion with unstable versions.
- We need to configure the U1’s open-source environment to ensure users can modify the code and run it on U1 machines smoothly.
Once these preparations are complete, we will release the code as promised. And beyond this campaign, we will also share regular progress updates on the firmware open-sourcing process, addressing key questions from the community after the crowdfunding ends.
Notes
[1] This data was obtained by printing with PLA filament and a 0.4 mm standard-flow nozzle, using a 0.2 mm layer height, 200 mm/s outer wall speed, and 250 mm/s infill speed. “Others” refers to 3D printers that use a filament changer to swap materials.
[2] “Purging for Color Change” here refers specifically to the process of squeezing out the remaining material from the extrusion path during color or material changes. In the following operations, the U1 produces a small amount of scrap material that isn’t part of what we define as “Purging for Color Change”: (1) clearing leftover filament from the nozzle before each print job; (2) wiping the nozzle tip during a color change (i.e., building a prime/wiping tower); (3) performing flow rate calibration.
[3] This is a typical result from Snapmaker Lab tests and is for reference only.
[4] Filament usage may vary with model size, color layout, and print settings. In Snapmaker Lab tests under similar conditions, the U1 used roughly 17% to 47% of the filament required by other single-head printers for the same multi-color prints.
[5] This data was measured using clean nozzles. Calibrating with an unclean nozzle could lead to less accurate results.
[6] Detection capabilities will be enabled in December 2025 through an OTA firmware update.
[7] This data was obtained using Snapmaker ABS filament, under a printing temperature of 280°C.
[8] In addition to the items shown, the tool and accessory box will also include thermal grease and white lithium grease. Packaging layout may change accordingly; image for reference only.
