Snapmaker U1 3D Printer
5X More Speed. 5X Less Waste.
Make More, Waste Less
Perspectives From Pros
Snapmaker has developed a tool changer that not only works well, but is a ready-to-go solution with little to no setup time.
The Snapmaker U1 is the machine we've been waiting for – an affordable four-color printer that doesn't waste your filament. It has speed, style, and ready-to-go simplicity.
The Snapmaker U1 is a game-changer for affordable multi-filament 3D printers, offering unmatched speed and much less waste.
It was a pleasant experience printing multiple materials with the Snapmaker U1 machine... the tool changer and printing features really provide effortless multi-material printing.
The level of precision of this printer, especially considering it uses 4 different toolheads, is amazing... tool alignment and automatic flow calibration obviously work perfectly.

Insights From Real Users
No More Purging for Color Change
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.
Rock-Solid & Precise Locks
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.
Less Waste Means Serious Savings
So. Much. Waste. On other 3D printers, printing a multi-color model leaves a mountain of trash – often 3 or 4 times more material is wasted than actually ends up in the model! The U1 avoids waste through smart tool switching, saving filament, saving money, and even helping the environment.
How Much Can You Save in a Year?
“Others” refers to 3D printers that use a filament changer to swap materials.
* Based on PLA filament at an average cost of $15/kg, with a printing frequency of one piece per week.
Pick Your Material Pairs
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.

PETG Support
PVA Support
PVA is costly but necessary for some creations. U1's 4-toolhead system minimizes purges to little or zero, so you can pair PVA with other materials freely, reduce waste greatly, and save money dramatically!
With 4 toolheads, U1 prints stable PETG components to support your creation safely, avoiding mid-print warping. These supports are easy to detach without damage, so you can skip tedious prying and keep your finished prints intact.
Blend Rigid and Flexible Materials

PETG+TPU
PLA+TPU
U1 supports printing your own customized shoe by feeding TPU materials in different colors and hardness levels, no need for separate prints or gluing. And the PLA support is easy to peel off without ruining your creation.
With 4 individual extruders, you can match flexible TPU and rigid PETG together, print more creative artwork such as a 3D printed hand bag.
Smooth Print Starts with Smart Calibration
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.
Toolhead Offset Calibration
The U1 automatically aligns XYZ offsets between multiple toolheads, keeping offsets within 0.04mm[5] for sharp prints without vertical shifts.
Vibration Compensation for Consistent Prints
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.
Fine-tuned Extrusion for Exquisite Details
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 First Layer Matters Too
The automatic mesh bed leveling delivers a flat, grippy first layer, setting the stage for every print.
Effortless Filament Management
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.
Manage Your Prints with Ease
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-lapses videos to replay your creation in motion. Easy print management is right at your fingertips.
Capture the Highlights, Skip the Messes
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.
Creative Vibes, Uplifted by U1
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.

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]This is a typical result from Snapmaker Lab tests and is for reference only.
- [3] “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.
- [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.
